What is the point of oxide-bonded silicon carbide products?
- Sep 04, 2018 -

The emergence of oxide-bonded silicon carbide products solves the problem of high cost and poor effect of damaged silicon carbide waste. It is characterized by oxide-bonded silicon carbide products without oxidation, high density, processed into various particles, according to reasonable distribution. It is mixed for 24 hours, then semi-dry pressed by a vibration molding machine, dried in a drying chamber at 80-100 ° C, and then placed in a gas shuttle kiln, and the firing time is 18 hours, and the heat is kept for 3 hours. The fire temperature is 1350 °C.

 

The prepared oxide-bonded silicon carbide product has the advantages of high temperature resistance, wear resistance, oxidation resistance, good thermal shock resistance, long service life, and the like, and is applied to ceramics, glass, steel, chemical, powder metallurgy and other industries. Silicon carbide bricks are a widely used oxide-bonded silicon carbide product.

 

Since the amount of binder added during preparation is relatively small, the content of silicon carbide in the oxide-bonded silicon carbide product is generally higher, usually above 85%, and the content of silicon carbide is proportional to the thermal conductivity of the silicon carbide brick. Therefore, the thermal conductivity of oxide-bonded silicon carbide products is greater than that of other similar products, which is why the heat transfer rate of oxide-bonded silicon carbide products is fast.

 

In addition to the fast heat transfer rate, the oxide-bonded silicon carbide product has a smoother appearance and smaller dimensional error, and the physical density of the oxide-bonded silicon carbide product is also larger than that of the conventional product, and the compressive strength and the bending strength are also better. It is also resistant to erosion and erosion of materials.http://www.hshightec.com/
