The carbon ceramic C/C-SIC cracking furnace is a heating furnace used to crack and decompose carbon ceramic materials through high-temperature treatment. It is suitable for heating furnaces in nitrogen or vacuum atmospheres.
Carbon ceramics are a special ceramic material composed of silicon carbide and other additives that have high temperature stability and good mechanical properties.
Carbon ceramic pyrolysis is usually achieved by heat treatment at high temperatures. This heat treatment process involves placing the carbon ceramic in a high-temperature furnace and heating it in a controlled atmosphere. During the heat treatment process, carbon ceramic will undergo thermal decomposition reaction, decomposing it into silicon carbide and other gases. This process is reversible, so carbon ceramic cracking can be performed multiple times.
The main purpose of carbon ceramic cracking is to change the shape and structure of carbon ceramics, which is usually used to prepare ceramic parts with complex shapes or to obtain specific pore structures. During the heat treatment process, due to the thermal decomposition of carbon ceramics, the material will undergo volume shrinkage and shape changes to achieve the desired shape design. In addition, the pyrolysis process can also create pores and change the density and porosity of the material, thereby modulating its mechanical and adsorption properties.
The carbon ceramic cracking furnace is an important equipment in the preparation of carbon ceramic C/C-SIC and is widely used in the preparation of ceramic materials, the preparation of composite materials and the design of functional materials. By controlling heat treatment conditions, the properties and morphology of carbon ceramic materials can be controlled to meet different process needs.

The main features of carbon ceramic cracking furnace are:

1. The interior of the High-Temperature Sintering Furnace is equipped with multi-sided zoned heating to ensure optimal temperature uniformity.
2. It has effective shielding for insulation and heating materials to avoid corrosion caused by volatilization in the base material. 3. Gas corrosion and carbonization of insulation and heating elements, etc.
4. Easy-to-control multi-channel exhaust system, finding a balance between uniform temperature and smooth exhaust
5. Vacuum or nitrogen pressure self-balancing automatic control system
6. A rapid cooling circulation system can be set up for cooling.
7. The transfer vehicle configured with the impregnation furnace can achieve seamless transfer.
