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.
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.

What Is A Atmospheric Furnace?
What Is Cold Isostatic Pressing (CIP)?
Cold Isostatic Pressing (CIP) is a process used to compact and mold powders and other materials into a desired shape by applying hydrostatic pressure at room temperature. The process is performed using a flexible mold, typically made of rubber or plastic, that is filled with a liquid pressure medium such as water, oil, or a specialized fluid.
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.
What Causes An Increase In Pressure Within A High-pressure Reactor?
Increasing pressure inside a pressure reactor can be achieved through various means. One common method is by heating a sealed pressure vessel, where temperature and pressure increase proportionately, impacting reaction kinetics. Alternatively, the reaction occurring inside the vessel can induce pressure, and agitation can accelerate this process.
In situations where heating is unsuitable or insufficient pressure is generated, manual pressurization is possible with a compressed gas source, such as a compressor or a pre-compressed canister of inert gas.
Pressure reactors utilize pressure relief valves to safely regulate and maintain pressure, emphasizing their reliable and safe operation.
What Is The Use Of Atmosphere Furnace?
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:

What Are The Advantages Of Cold Isostatic Pressing?
- High green strength: Machining of the compacted material in its green state becomes more feasible.
- Materials that are hard to press: Isostatic pressing can be performed on powders without the need for water, lubricants, or binders, making it applicable to a wider range of materials.
- Predictable shrinkage during sintering is achieved due to the high compaction and uniform density.
- Time and cost savings in post-processing are possible due to the ability to create large, complex, and near-net shapes.
- Large aspect ratio parts with uniform density can be produced, resulting in improved quality.
- Green strength enables efficient in-process handling and treatment, reducing production costs.
What Is A Cold Isostatic Press?
A cold isostatic press (CIP) is a machine used to compact and mold powders and other materials into a desired shape.
The process works by filling a flexible mold, usually made of rubber or plastic, with a liquid pressure medium like water, oil, or a specialized fluid. This mold is then placed in a closed container, and equal pressure is applied to each surface to achieve a high-pressure environment.
The pressure results in an increase in the product's density and allows it to take on the desired shape.
Cold isostatic pressing is performed at room temperature, in contrast to hot isostatic pressing which is carried out at higher temperatures.
