Warnings
Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.

FAQ
What Is A Tube Furnace?
Laboratory tube furnace is one classic external heating high temperature tube furnace, also named hot wall heating furnace.
According to the different working temperature, furnace tube material usually can be transparent quartz tubes, high purity alumina ceramic tubes and high strength metal alloy tubes.
To meet different thermal researching purposes, tube furnace can be designed with multi heating zones, so as to have a flexible control of temperature gradient in the tube working chamber; furnace tube can work with a controlled atmosphere working environment or a high vacuum working environment.
What Is CVD Furnace?
Chemical vapor deposition (CVD) is a technology that uses various energy sources such as heating, plasma excitation or light radiation to chemically react gaseous or vapor chemical substances on the gas phase or gas-solid interface to form solid deposits in the reactor by means of chemical reaction.To put it simply, two or more gaseous raw materials are introduced into a reaction chamber, and then they react with each other to form a new material and deposit it on the substrate surface.
CVD furnace is one combined furnace system with high temperature tube furnace unit,gases control unit, and vacuum unit, it is widely used for experiment and production of composite material preparation, microelectronics process, semiconductor optoelectronic, solar energy utilization, optical fiber communication, superconductor technology, protective coating field.
How Does A Tube Furnace Work?
Tube furnace heating elements are placed surrounding the cylindrical cavity, furnace can only heat the samples in the cylindrical cavity through indirect thermal radiation, since furnace tube can prevent sample material from contacting with furnace heating elements and insulation materials, so tube furnace creates a clean isolated heat chamber and reduce risks of the sample material contaminating by the furnace.
How Does CVD Furnace Work?
CVD furnace system consists of high temperature tube furnace unit, reacting gas source precise control unit, vacuum pump station and corresponding assembling parts.
Vacuum pump is to remove the air from the reacting tube,and make sure there is no unwanted gases inside the reaction tube, after that the tube furnace will heat the reaction tube to a target temperature, then reacting gas source precise control unit can introduce different gases with a set ratio into the furnace tube for the chemical reaction, the chemical vapor deposition will be formed in the CVD furnace.
What Is The Application For Tube Furnace?
Tubular furnace is mainly used in metallurgy, glass, heat treatment, lithium anode and cathode materials, new energy, abrasives and other industries, and is a professional equipment for measuring materials under certain temperature conditions.
Tube furnace features simple structure, easy operation, easy control and continuous production.
Tube furnace is also widely applied in the CVD (chemical vapor deposition) and plasma enhanced CVD systems.
Which Gas Is Used In CVD Process?
There are tremendous gas sources can be used in the CVD process, the common chemical reactions of CVD includes Pyrolysis, photolysis, reduction, oxidation, redox,so the gases involved in these chemical reactions can be used in the CVD process.
We take CVD Graphene growth for an example, the gases used in the CVD process will be CH4,H2,O2 and N2.
How Many Different Types Tube Furnace?
Tube furnace can work with different mechanical functions smoothly, so there are many different types tube furnace variations for different experiment purposes, typical furnace furnaces are as below:
- Horizontal tube furnace
- Vertical tube furnace
- Split tube furnace
- Rotary tube furnace
- Tilting tube furnace
- Sliding tube furnace
- Fast heating and cooling tube furnace
- Continuous feeding and discharging tube furnace
What Is The Advantage Of CVD System?
- Wide range of films can be produced, metal film, nonmetal film and multi-component alloy film as required. At the same time, it can prepare high-quality crystals that are difficult to obtain by other methods, such as GaN, BP, etc.
- The film forming speed is fast, usually several microns per minute or even hundreds of microns per minute. It is possible to simultaneously deposit large quantities of coatings with uniform composition, which is incomparable to other film preparation methods, such as liquid phase epitaxy (LPE) and molecular beam epitaxy (MBE).
- The working conditions are carried out under normal pressure or low vacuum conditions, so the coating has good diffraction, and the workpieces with complex shapes can be uniformly coated, which is much superior to PVD.
- Due to the mutual diffusion of reaction gas, reaction product and substrate, a coating with good adhesion strength can be obtained, which is crucial for preparing surface strengthened films such as wear-resistant and anti-corrosion films.
- Some films grow at a temperature far lower than the melting point of the film material. Under the condition of low temperature growth, the reaction gas and reactor wall and impurities contained in them almost do not react, so a film with high purity and good crystallinity can be obtained.
- Chemical vapor deposition can obtain a smooth deposition surface. This is because compared with LPE, chemical vapor deposition (CVD) is carried out under high saturation, with high nucleation rate, high nucleation density, and uniform distribution on the whole plane, resulting in a macroscopic smooth surface. At the same time, in chemical vapor deposition, the average free path of molecules (atoms) is much larger than LPE, so the spatial distribution of molecules is more uniform, which is conducive to the formation of a smooth deposition surface.
- Low radiation damage, which is a necessary condition for manufacturing metal oxide semiconductors (MOS) and other devices
What Are The Advantages Of Using A Tube Furnace?
What Does PECVD Stand For?
PECVD is a technology that uses plasma to activate reaction gas, promote chemical reaction on the surface of substrate or near surface space, and generate solid film. The basic principle of plasma chemical vapor deposition technology is that under the action of RF or DC electric field, the source gas is ionized to form a plasma, the low-temperature plasma is used as the energy source, an appropriate amount of reaction gas is introduced, and the plasma discharge is used to activate the reaction gas and realize chemical vapor deposition.
According to the method of generating plasma, it can be divided into RF plasma, DC plasma and microwave plasma CVD, etc...
What Safety Precautions Should Be Taken When Using A Tube Furnace?
What Is The Difference Between CVD And PECVD?
The difference between PECVD and traditional CVD technology is that the plasma contains a large number of high-energy electrons, which can provide the activation energy required in the chemical vapor deposition process, thus changing the energy supply mode of the reaction system. Since the electron temperature in the plasma is as high as 10000K, the collision between electrons and gas molecules can promote the chemical bond breaking and recombination of the reaction gas molecules to generate more active chemical groups, while the whole reaction system maintains a lower temperature.
So compared to the CVD process, PECVD can carry out the same chemical vapor deposition process with a lower temperature.
