Zwart siliciumcarbide is gemaakt van kwartszand, petroleum coke and silica as the main raw material, through the resistance furnace high temperature smelting. De hardheid ligt tussen korund en diamant, mechanische sterkte is hoger dan korund, broos en scherp.
What are the properties of black silicon carbide provided by black silicon carbide manufacturers? Let’s learn more about it with Henan Superior Abrasive.

Voordelen van zwart siliciumcarbide

Zwart siliciumcarbide, with metallic luster, contains more than 95% SiC, with greater strength than green silicon carbide, but lower hardness, mainly used for grinding cast iron and non-metallic materials.

Molecular formula is SiC, its hardness is between corundum and diamond, mechanische sterkte is hoger dan korund, can be used as abrasives and certain other industrial materials. Industrial silicon carbide was successfully developed in 1891 and is an early man-made abrasive. Although a small amount of silicon carbide exists in meteorites and the earth’s crust, no mining source has been found to date.

Zwart siliciumcarbide bevat ongeveer 98.5% SiC, its toughness is higher than that of green silicon carbide, and is mostly used for processing materials with low tensile strength, zoals glas, keramiek, steen, vuurvaste materialen, gietijzer en non-ferro metalen.

Silicon carbide advantages

Due to its stable chemical properties, hoge thermische geleidbaarheid, lage thermische uitzettingscoëfficiënt en goede slijtvastheid, silicium carbide is used as an abrasive, but also has many other uses, bijvoorbeeld: een speciaal proces om siliciumcarbide te poedercoaten in de waaier van een hydraulische turbine of de binnenwand van het cilinderlichaam, which can improve its wear resistance and extend the service life of 1 tot 2 keer; used to make refractory materials, zonnesteek, kleine maat, lichtgewicht en hoge sterkte, goed energiebesparend effect. Laagwaardig siliciumcarbide (bevatten ongeveer 85% SiC) is a better deoxidizer, die de snelheid van staalproductie kan versnellen, en vergemakkelijken de controle van de chemische samenstelling, de kwaliteit van staal verbeteren. In aanvulling, silicon carbide is also used in large quantities to make electric heating elements silicon carbon rods.

Silicon carbide is very hard, has excellent thermal conductivity, is a semiconductor, and can resist oxidation at high temperatures.
