Refractory Grade Silicon Carbide

Refractory Grade Silicon Carbide

Refractory grade silicon carbide is widely used in the production process of ceramics, with very good high temperature resistance, can be used in high temperature and high pressure environment. Refractory grade silicon carbide can be divided into several grades, such as 97#, 95#, 92#, 90#, 88# and 85#, with a particle size of 200 mesh. As different users have different applications, manufacturers can process refractory grade silicon carbide into lumps, grains or powders of different particle sizes to meet the needs of different users.

What Is Refractory Grade Silicon Carbide?

Refractory grade silicon carbide is a polycrystalline compound composed of silicon and carbon with the chemical formula “SiC”, which is characterized by high temperature resistance, corrosion resistance and high strength. Fire-resistant grade silicon carbide is able to maintain stability and strength at extremely high temperatures, withstanding temperatures as high as 2,000 degrees Celsius. It is also highly resistant to acidic or alkaline chemically corrosive liquids, and refractory grade silicon carbide performs well when subjected to higher tensile and compressive strength tests. Due to its excellent properties, it is widely used in the production processes of ceramics, metallurgy and abrasives.

Production method And Processing For Refractory Grade Silicon Carbide

Production Process For Refractory Grade Silicon Carbide
Before producing refractory grade silicon carbide, quartz sand, petroleum coke and wood chips with high purity need to be prepared as raw materials for refractory grade silicon carbide. High purity quartz sand is rich in silica, which directly affects the grade of silicon carbide. Therefore, it needs to be screened by strict manual and precision instruments before production to ensure that the refractory grade silicon carbide produced meets user requirements. After that, the staff will mix the raw materials proportionally and add other synthetic materials according to user requirements. After mixing, the materials will go through the molding process to form the initial shape of refractory grade silicon carbide. Since refractory grade silicon carbide needs to be sintered in a high-temperature environment, it is usually heated by an electric furnace to make the bond between the silicon carbide particles stronger, and enhance its mechanical properties and wear resistance. The sintered refractory grade silicon carbide also needs to be ground and polished on its surface to enhance its corrosion resistance.
Refractory Grade Silicon Carbide Processing
As different users have different use environment, we need to process the produced refractory grade silicon carbide. First of all, we will manually screen the refractory grade silicon carbide according to the grade, and then it will be detected by the automated screening equipment, and then it will be preliminarily processed by the professional crushing equipment. After preliminary processing, the refractory grade silicon carbide is in the form of small particles, with particle sizes of 1mm-3mm, 3mm-5mm and 5mm-10mm, which will be filtered through the screen, and the ones that do not meet the requirements will be re-processed by the equipment. If users need powdered refractory grade silicon carbide, we also use more precise grinding equipment to process them, they will be processed into powder with particle size of 200Mesh, 300Msesh. The processed refractory grade silicon carbide will be transported to the packing area by the conveyor machine, and usually packaged in tonnage bags, iron drums and sachets, with appropriate moisture-proof treatment, and finally loaded by forklift trucks, waiting for shipment.
