Black Silicon Carbide (SiC) is an industrial mineral renowned for its exceptional hardness, thermal conductivity, and chemical resistance. Manufactured through a high-temperature process, this crucial material has become indispensable across a range of manufacturing sectors, from abrasives to electronics and refractories. As demand increases for high-performance materials in Asia and beyond, Vietnam has emerged as a significant center of Black Silicon Carbide production, exporting to markets worldwide.
Black Silicon Carbide is a synthetic crystalline compound formed by heating high-purity silica sand and petroleum coke in an electric resistance furnace at extremely high temperatures, often surpassing 2000°C. The process yields a dense, angular black crystal, which is crushed and classified into a range of grit and powder sizes. Noted for its high Mohs hardness (above 9.1), Black Silicon Carbide offers:
- Outstanding wear resistance for use in grinding and cutting
- Superior thermal shock tolerance for applications in refractories
- Excellent chemical inertness, even at high temperatures
Industry professionals rely on these properties for grinding, lapping, surface treatment, and thermal applications, as well as in advanced ceramics and metallurgy.
The Vietnamese Black Silicon Carbide industry has seen rapid development due to favorable access to raw materials, low energy costs, and strategic market positioning. Supported by modern infrastructure, Vietnamese manufacturers have gained a strong reputation for quality, reliability, and logistical efficiency. Vietnam's SiC export sector particularly benefits from:
- State-of-the-art production lines using the Acheson process
- ISO-compliant quality management systems
- Flexibility in customizing granule sizes, purity, and packaging
- High-capacity logistics and timely delivery for international buyers
New He Qiao Shareholdings Company is one of Vietnam's largest producers, with an annual capacity of approximately 60,000 metric tons. The company operates advanced electric resistance furnaces and offers a broad portfolio, including high-purity Black Silicon Carbide grains, specialized blends for abrasives, and low-sulfur SiC products for foundry applications. NHQ's adherence to ISO 9001 and ISO 14001 standards assures international buyers of high product consistency and environmental management.[9]
Well established for its reliable supply of abrasive grade Black Silicon Carbide, Hai Duong Joint Stock Company maintains long-term partnerships with manufacturers and abrasive tool makers both in Vietnam and overseas. Their quality control is strict, ensuring all products conform to industry-standard size distributions.[10]
With a robust export network, Vietnam Abrasives Co. Ltd delivers high-purity, performance-driven Black Silicon Carbide for abrasive tools, grinding wheels, sandpaper, and value-added industrial solutions. The company demonstrates strong capabilities in international logistics and customer support.[11]
Specializing in lump and coarse Black Silicon Carbide, NAM HAO is a trusted supplier for metallurgical operations, foundries, and bulk abrasives traders seeking consistent quality on large-scale orders.[12]
Tan Ha Kieu JSC focuses on providing SiC powder and granules to customers seeking competitive options for ceramics, refractory products, and abrasive manufacturing.[13]
Producing industrial-grade Black Silicon Carbide in Vietnam entails a rigorous, multi-step process, which includes:
Carefully chosen quartz sand and petroleum coke or anthracite are mixed and pretreated. Low impurity levels are critical for obtaining SiC suitable for both abrasive and electronic-grade uses. Some manufacturers use high-quality silica to ensure optimal grain strength and combine it with imported or premium local coke.[5]
The key step is the Acheson process, which takes place in an electric resistance furnace. The carbothermic reduction of silica occurs at temperatures from 2000°C to 2500°C:
This reaction produces large SiC crystals over a span of 36-72 hours, after which the furnace is slowly cooled to prevent thermal shock.[2]
After the cooling stage, the crude SiC blocks are extracted, and metallic impurities are removed. The blocks are then crushed and milled to a specific grain size, with over 60 standard grit sizes available for different end-uses.
Processed grains are washed, graded, and magnetically separated to ensure grain purity, correct sizing, and low magnetic content, which is particularly important for high-end electronics and precision abrasives.
Quality control laboratories conduct rigorous tests for hardness, purity, particle shape, and distribution before shipment. Packaging is customized as per customer requirements, ranging from 25 kg bags to 1-ton jumbo sacks, fully compliant with international transport safety regulations.
Thanks to its versatility, Black Silicon Carbide's application spectrum covers:
- Cutting and grinding wheels for metals, glass, and ceramics.
