Silicon carbide (SiC), also known as carborundum, is a hard chemical compound containing silicon and carbon. They are widely used for abrasives, refractory, metallurgy, and SiC wafer, etc. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests.

We have black and green silicon carbide, which includes not only abrasives grade, but also metallurgy grade, refractory grade, and high purity 4N 5N 6N SiC.
Baotong Silicon Carbide New Material Co., Ltd. is a silicon carbide enterprise integrating production, processing and sales. Our manufacturer has one 26000Kva and 12500kva black silicon carbide smelting production line, and is equipped with segment sand and fine powder processing equipment, which can be customized according to customer requirements. Processing granularity.
In order to further meet the needs of our customers for silicon carbide, Baotong has built a new 40000Kva silicon carbide smelting production line, which has been put into use, and the monthly output of silicon carbide blocks has reached 6000-7000 tons.
Q1: Are you trading company or manufacturer?
A: We are manufacturer.
Q2: Are samples free or not?
A: Sample can be free of charge. Only shipping needs to be paid by your side.
Q3. Can you customize the grain size or parameters according to my requirement?
A: Yes, we can.
Q4. Do you test all your goods before delivery?
A: We have laboratories to test the chemical and physical properties of our SiC. We will repeatedly test during production and before shipping to ensure that the product meets the appointed standards.
Looking forward to receiving your inquiry.
Please feel free to ask me if you have any questions. Thank you ^^
