Introduction
A tube furnace with alumina tube is a laboratory equipment used for high-temperature applications up to 1500°C. It is commonly used in research and industrial settings for various processes such as material synthesis, chemical vapor deposition, vacuum sintering, and heat treatment. The furnace consists of a heating element, typically made of silicon carbide (SiC), enclosed within an alumina ceramic tube. The alumina tube provides excellent thermal insulation and resistance to high temperatures, acids, and alkalis.
Tube furnaces offer several advantages, including compact design, precise temperature control, and a relatively small workspace. They are particularly suitable for applications requiring precise temperature regulation and a clean, inert environment. The alumina tube's high purity and thermal stability make it ideal for high-temperature processes, ensuring minimal contamination and extended service life.

Principle
Tube furnaces use a heating element, such as a resistive heating coil or a graphite rod, to heat a process tube. The process tube is typically made of a ceramic material, such as alumina, and is placed inside a furnace chamber. The furnace chamber is then insulated to minimize heat loss. The temperature of the process tube is controlled by a temperature controller, which monitors the temperature of the process tube and adjusts the power to the heating element accordingly. Tube furnaces are used for a variety of applications, including heat treating, annealing, and sintering.

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.
