High temperature resistant silicon carbide crucible with good thermal conductivity

Short Description:

The silicon carbide crucible is made of high purity silicon carbide particles. Silicon carbide has extremely high refractoriness and good oxidation resistance, and can maintain its original physical and chemical properties at high temperatures above 2000 ° C. The silicon carbide crucible also has high thermal conductivity and good thermal stability, which can effectively transfer heat and prevent the molten metal in the crucible from overheating.

Product Detail

Product Tags

Our silicon carbide crucible is fabricated by high purity isostatic pressing and has good thermal conductivity and high temperature resistance. In the process of high temperature use, the coefficient of thermal expansion is small, and it has a certain strain resistance to acute heating and acute cooling. It has strong corrosion resistance to acid and alkali solution and excellent chemical stability. The specific model can be customized by drawing and sample, and the material is domestic graphite and imported graphite to meet the different needs of customers.

The characteristics of silicon carbide crucible are introduced

Silicon carbide crucible is silicon carbide material, graphite material made of scientific formula, it is different from the general material, when the temperature increases the silicon carbide crucible not only unchanged softening, strength but increased, at 2500 degrees, tensile strength but doubled.

1, advanced technology: the use of the world's advanced cold isostatic pressing forming method to make crucible, product isotropy is good, high density and strength, uniform density, no defects.

2, good oxidation resistance, fully consider the design of the formula to prevent the oxidation of graphite during use.

3, unique glaze layer: the surface of the crucible has multiple layers of characteristics of the glaze layer, coupled with dense forming materials, greatly improve the corrosion resistance of the product, extend the service life of the crucible.

4, high thermal conductivity: the use of natural graphite material, isostatic pressing molding method, the production of crucible wall is thin, fast thermal conductivity.

5, significant energy saving: the crucible made of efficient thermal conductivity materials can save a lot of energy for users in the process of use.
