Refractory Materials are usually non-metallic materials having those chemical and physical properties that make them applicable for structures, or as components of systems, that are exposed to environments above 1,000 °F (811 K; 538 °C)。

Black Fused Alumina




Black Fused Alumina has the following advantage: high hardness, strong tenacity, good self-sharpening, better cohesiseness, higher durability, less heat generated in grind-ing and giving the metal works high finish, less power weak-ened in grinding. It is mostly used in grinding and polishing stainless steel, metal works, optical glass, bamboo or articles.
