The different types of silicon carbide are as follows:
1. Sintered silicon carbide (SSC): This type of silicon carbide is produced from pure SiC powder with non-oxide sintering aids. It undergoes conventional ceramic forming processes and is sintered in an inert atmosphere at temperatures up to 2000°C or higher. It has low density, high strength, low thermal expansion, high thermal conductivity, high hardness, excellent thermal shock resistance, and superior chemical inertness.
2. Nitride bonded silicon carbide (NBSC): NBSC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon, forming silicon carbide. The reaction product bonds the silicon carbide particles. It has similar properties to sintered silicon carbide and is highly wear resistant, with good mechanical properties including high temperature strength and thermal shock resistance.
3. Reaction bonded silicon carbide (RBSC): RBSC is also made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. However, the infiltration process is different, resulting in a lower density material compared to NBSC. RBSC also has good mechanical properties, high wear resistance, and excellent thermal shock resistance.
These different types of silicon carbide offer a range of properties and are used in various applications such as abrasives, refractories, ceramics, resistance heating, flame igniters, electronic components, and structural and wear applications. Silicon carbide is known for its high mechanical strength, low thermal expansion, high thermal conductivity, high hardness, excellent thermal shock resistance, and superior chemical inertness. It is also an electrical conductor and can withstand high temperatures, making it suitable for use in high-performance applications.
