Silicon carbide crucibles are ideal for metal smelting. Their higher shock resistance compares with traditional graphite crucibles and corrosion-resistance makes cleaning simpler than ever. They’re also lightweight and easy to transport between locations. Before using a crucible for melting, it must first be preheated and tempered – this can be accomplished either by placing it on a hot plate or gradually increasing the temperature in a furnace. They are easy to clean Silicon carbide crucibles are durable materials designed for melting and casting metals and alloys. Easy to clean and resistant to corrosion, thermal shock and chemical attack as well as erosion make them suitable for use in metallurgical applications …

Silicon carbide is an extremely hard, synthetically produced crystalline compound of silicon and carbon. Both friable (green) and regular (black) varieties of this material can be produced through heating silica sand with carbon, typically petroleum coke, in an open furnace called an “Acheson”. Razor-sharp grains make this tool suitable for easily sanding glass, plastic and medium-density fiberboard with minimal pressure; however, harder materials like metal or wood may need additional work to achieve complete cutting action. Furthermore, its razor-sharp grains can also be used to polish automotive parts, remove rust from wood floors refinish them as well as deburr metal surfaces. Hardness Silicon carbide (SiC) is an extremely hard abrasive …

Silicon carbide moissanite is a rare gemstone named after French chemist Henri Moissan. He discovered it while studying meteorites in Arizona in 1893 and at first thought the tiny particles might be diamonds; but Moissan immediately recognized them as something new and different. Today, synthetic moissanite has become an increasingly popular alternative to diamond for jewelry purposes. It can be created using various processes including chemical vapor deposition (CVD) and flux growth. Natural Moissanite (SiC), although natural silicon carbide can occur in nature, is relatively rare and lab created moissanite is typically sold as jewelry store inventory. Moissanite shares more gemological properties with diamond than any other synthetic gem simulant …
