Sic Tubes Use/Maintenance Methods                                                                                                                 

(1) Acid and alkali resistance: in acid resistance, alkali resistance, oxidation resistance, silicon carbide due to the protective film of silica, acid resistance is strong, alkali resistance is slightly poor.

(2) Anti-oxidation: when the silicon carbide material is heated to 1300 ° C in the air, the silicon carbide crystal surface begins to form a protective layer of silica. 

(3)With the thickening of the protective layer, the continued oxidation of the internal silicon carbide is prevented, so that the silicon carbide has better oxidation resistance. 

(4)When the temperature reaches 1900K(1627℃) above, the protective film of silica begins to be destroyed, and the oxidation of silicon carbide is aggravated, so 1900K is the high working temperature of silicon carbide in the atmosphere containing oxidants.

Q1: What types of furnaces can a silicon carbide crucible be used in? 

A1: Silicon carbide crucibles are primarily used in electric resistance furnaces, induction furnaces, and ceramic kilns. They are also used in certain types of gas-fired furnaces and in certain types of torch melting operations. 

Q2: What types of metals can be melted in a silicon carbide crucible?

A2: Silicon carbide crucibles are best suited to melting non-ferrous metals such as aluminum, copper, brass, silver, and gold. They can also be used to melt ferrous metals such as iron and steel, but they require higher temperatures and more precise control of the melting process. 

Q3: What are the advantages of using a silicon carbide crucible? 

A3: Silicon carbide crucibles offer several advantages over other types of crucibles. They are capable of withstanding extremely high temperatures and are highly corrosion-resistant. They are also lightweight and easy to handle. Additionally, they are very durable and can be used multiple times.
