OKAYAMA GIKEN (Minerals) Co., Ltd. has been selling black silicon carbide raw materials most of the time since 2010. We have own silicon carbide factory in Ningxia China, mainly producing silicon carbide and deep processing of silicon carbide products. The annual production capacity reaches 85,000 tons/year. The company uses anthracite smelting technology, with high silicon carbide content, high-quality and dense silicon carbide products with a content greater than 98.00%, a specific gravity greater than 3.20, and a bulk density greater than 1.65g/cm3.
At present, the company has passed the "REACH" certification and continuously and stably exports high-quality silicon carbide products overseas.
The black silicon carbide produced by our company is a non-metallic mineral product produced under high temperature conditions above 1800 degrees Celsius with quartz sand and petroleum coke as basic raw materials. During the high-temperature smelting process, silicon carbide has the characteristics of high temperature resistance, oxidation resistance, wear resistance, good thermal conductivity and thermal shock resistance. It is more durable than traditional bauxite or high-alumina refractory materials, and can effectively extend the service life of equipment, improve production efficiency and reduce maintenance costs.
Exceptional Hardness and Performance at an Affordable Price: With a Mohs hardness of 9.2, Black Silicon Carbide is an excellent choice for cutting, grinding, and polishing. At OKAYAMA GIKEN (Minerals) Co., Ltd., we offer this superior material at a highly competitive price point, making it an accessible solution for industries looking for both performance and value.
Sharpness for Efficient Material Removal: The sharpness of each particle ensures quick, efficient material removal. As a supplier, we are committed to providing Black Silicon Carbide that delivers maximum efficiency in abrasive applications—helping our clients to optimise productivity at a fraction of the cost of premium alternatives.
Thermal Stability: Black Silicon Carbide maintains its integrity even under extreme temperatures, offering reliable performance in high-heat applications. As a supplier, we pride ourselves on delivering materials that stand the test of time in harsh working environments, all at a price that fits your budget.
High Chemical Purity: Our Black Silicon Carbide is of exceptional purity, with minimal impurities that ensure reliable, consistent performance. At OKAYAMA GIKEN, we guarantee the purity of our product while offering prices that make it a cost-effective choice for any project.
Versatile Grain Sizes: Available in a range of particle sizes, our Black Silicon Carbide can be tailored to suit your specific needs—whether for coarse grinding or fine polishing. As a supplier, we offer flexibility and customisation without the high cost typically associated with such versatility.
OKAYAMA GIKEN (Minerals) Co., Ltd manufactures and supplies a wide range of silicon carbide products to a wide range of industries including, but not limited to metallurgy, refractories, casting, abrasives, ceramics, grinding wheels, insulation, surface treatment, etc.
