Silicon carbide abrasives are hard and sharp materials used in sandpaper, with razor-sharp grains for efficient metal, stone, and medium-density fiberboard sanding applications with minimal pressure application. Unfortunately, silicon carbide wears down more quickly than its aluminum oxide counterparts due to brittleness and narrow grain size differences between grains. High hardness Silicon carbide grinding wheels boast superior hardness to aluminum oxide abrasives, withstanding extreme stress without becoming worn or frayed. Furthermore, silicon carbide materials feature higher chemical resistance compared with many ceramic materials and thus protecting from chemical corrosion. Due to these properties, silicon carbide grinding wheels are widely used across applications. Corundum and silicon carbide abrasives are among the …

Silicon carbide is produced through melting silica sand with carbon sources such as coal at high temperatures; this process is known as Lely’s method. Silica sand and graphitized petroleum coke carbon are the primary raw materials utilized in manufacturing. Additional auxiliary materials, like sawdust and salt, may also be utilized but do not contribute directly to chemical reaction. Cold Isostatic Pressing Silicon carbide production begins with the compaction process. Raw materials are mixed with binder and then compacted by extrusion or cold isostatic pressing into blocks or plates that will later be sintered under vacuum in order to give these finished parts their hardness and chemical resistance. Die compaction involves …
