Multi purpose, this product is suitable for industries such as powder metallurgy, oil bearing, chemical, glass, electronic ceramics, precision casting, aluminum alloy die-casting, magnesium alloy die-casting, zinc alloy die-casting, magnetic materials, etc.
chemical property:
The silicon carbide rod has good chemical stability and strong acid resistance. Under high temperature conditions, alkaline substances can erosion it.
Silicon carbon rod components can react with oxygen and water vapor for long-term use above 1000 ℃ as follows:
①Sic+2O2→Sio2+CO2 ②Sic+4H2O＝Sio2+4H2+CO2
As a result, the content of Sic2 in the component gradually increases, and the resistance gradually increases, leading to aging. If there is too much water vapor, it will promote the oxidation of SiC, and the H2 generated by the ② reaction will combine with the O2 in the air to form a vicious cycle. Reduce component lifespan. Hydrogen (H2) can reduce the mechanical strength of components. Nitrogen (N2) below 1200 ℃ can prevent SiC from oxidizing and reacting with SiC above 1350 ℃, allowing SiC to decompose chlorine (Cl2) and complete the decomposition of SiC.
