Known industry-wide as a producer of high quality silicon carbide (SiC) shapes and powders, Superior Graphite has the additional advantage of being one of the few manufacturers of both alpha (á)-SiC and beta (â)-SiC in business today. Our cutting-edge, continuous electro-thermal process and intricate wet attrition milling and air milling operations enable us to cost-effectively produce particle size ranges from a median of less than 0.5 micron, up to coarse 20 micron particles, including an assortment of macro and micro grits. The finest grades can be processed into sintered shapes that exhibit the excellent mechanical properties, hardness, corrosion resistance, and thermal conductivity required for high-performance applications.
Our SiC powders, known for their extreme hardness, are available in standard package sizes of 15 kg buckets, 150 kg drums, 320 kg bulk bags and custom packaging is available on request. Pressureless sintered SiC shapes are available in a range of sizes and thickness, with a water jet cutting in the green form allowing for custom shapes. We specialize in a variety of ceramic shapes and parts, including armor tiles among others.
