Application of green silicon carbide powder in ceramics
The appearance of green silicon carbide powder is green powder. It has good thermal conductivity and is widely used in many fields. What are the applications of this ultrafine powder in ceramics?
The thickness and size of green silicon carbide micropowder plates and columns vary, depending on the size of the car and the type of combustion products. The bearing capacity of the kiln car can be improved by reasonably changing the dimensions of the scaffolding components. Silicon carbide plates with a thickness of 25 to 30 mm are used for firing hollow porcelain products. When baking small abrasive products on the scaffold, the silicon carbide plate used is 450*240mm in size and 22mm in thickness. When baking heavy abrasive products, the plate thickness is 40 mm.
Because green silicon carbide micropowder is much more expensive than clay bricks, its use effect can be economically reasonable only if its service life is longer than that of clay bricks. The service life depends to a large extent on the green silicon carbide micropowder, the rationality of the production process, whether the frame and size of the scaffolding components are suitable, and whether their performance is compatible with the conditions and temperature when baking products on the scaffolding.
For example, when green silicon carbide powder is firing sanitary ceramics, high-voltage electric porcelain and abrasive products, the scaffolding on the kiln car bears a lot of load. Therefore, SiC-strength products are significant. Due to the low thermal stress when baking the product, dense silicon carbide refractories with high oxidation resistance can be used. High thermal stability of green silicon carbide micropowder is required when firing fine homeware, low-voltage electrical and high-frequency ceramics.
