Silicon Carbide SiC
Silicon Carbide is produced in resistance furnace, where exact mixtures of petroleumcoke and siliceous sand are burnt Silicon Carbide arise by increasing of crystals in the core of furnace during smelting. After cooled, furnace is disassambled, material is sorted and according to the quality is classified to material suitable for a production of abrasive grains and material suitable for metallurgy.
- For a production of abrasive grains is used material with silicon carbide SiC content min. 98%.
- For metallurgical_purposes is used material with silicon carbide SiC content minimal 90%.
- Silicon Carbide black is mainly used for a production of abrasive tools and instruments. Among further possibilities of usage belongs blasting by dry and wet method, production of refractory blocks, bricks, refractory cements and compacting mixtures.
- In electrotechnical industry for a production of insulating materials and lightning arresters. Wonderfuly is asserted as addition to laminated and frame saws at cutting of stone, then as filling agent to an epoxy resins for increasing of resistance against wear.
