Grønt silisiumkarbid is one of the valuable materials in nature. It is mainly used in abrasives, refractory materials and semiconductor materials. Especially in recent years, green silicon carbide micronized abrasive has been widely used for multi-line cutting and grinding in electronic engineering such as single crystal silicon, polycrystalline silicon and piezoelectric crystal. Green silicon carbide is made of quartz sand and petroleum coke as the main raw material, melted at high temperature, green translucent crystals, høy hardhet, strong cutting power, suitable for processing hard and brittle materials, such as cemented carbide, high-speed steel, ceramics and other non-metals and heating elements, thermal originals.
Main features
High bulk density, strong grinding ability, høy hardhet, Sterk skjæreevne, concentrated and uniform particle size distribution; high temperature resistance, high strength, God varmeledningsevne, impact resistance, as high temperature indirect heating material.
Applikasjoner
Grønn silicon carbide abrasive is widely used in a variety of industries, jade and gemstone polishing, glass, steel, plastic, elektronikk, mold casting, ildfaste materialer, construction and road building, clothing industry (denim sandblasting), beauty tools, hardware grinding, and also suitable for the manufacture of ceramic abrasive block grinding wheels.
Production process
Green silicon carbide manufacturing method is the same as black silicon carbide, Men renheten til råvarene som brukes krever en høyere grad av renhet, også dannet i motstandsovnen ved en høy temperatur på omtrent 2200 ° C., grønn, gjennomsiktig, sekskantet krystallform, SIC -innholdet er høyere enn svart, fysiske egenskaper og svart silisiumkarbid lignende, Men forestillingen er litt mer sprø enn svart, har også bedre termisk ledningsevne og halvlederegenskaper.
