Silicium carbide (SiC), ook wel carborundum genoemd, is a semiconductor material that is widely used in various industries due to its exceptional properties such as high thermal conductivity, lage thermische uitzetting, high resistance to chemical erosion, en hoge mechanische sterkte.
Silicon carbide comes in different grades, often categorized based on their purity, grain size, and the specific application they’re used for. Here are a few broad categories:
- Technical Grade SiC: This grade contains a high amount of impurities and is used in schurende toepassingen.
- Pure SiC: This is of higher quality than technical grade and is used in applications that require a higher degree of purity.
- Ultra-High-Purity SiC: This grade is of the highest quality and is used in demanding applications, zoals fabricage van halfgeleiders.
Different forms of silicon carbide include:
- Zwart siliciumcarbide (C): Black silicon carbide is very hard, scherp, and brittle. Its grain edges are sharp and it is of a certain capacity of heat transmission.
- Groen Siliciumcarbide (GC): Green silicon carbide is produced basically in the same manner as black silicon carbide in a resistance type electric furnace with petroleum coke, kwarts zand, en andere materialen. It is an extremely hard (Knoop 2600 or Mohs 9.4) manufactured material with high thermal conductivity (100 W/m-K).
Each of these grades and types can come in various grit sizes, from coarse particles to ultra-fine powders, and they can be bonded together in different ways to form composite materials or standalone objects.
