Aluminium silicon carbide which has a high melting point, a stability in a wide temperature range and an excellent hydration resistance
Silicon Carbide Whisker
Silicon carbide whisker used as reinforcement materials for ceramics, metals and plastics
Tateho successfully commercialized silicon carbide whiskers and silicon nitride whiskers from 1981 to 1982, by making full use of our crystal growth technology and firing control technology.
Tateho realized the mass-production of whiskers with our own technology, although it had been said to be difficult.
Whisker is also called "beard crystals", and it is a fine short fibrous crystal with few defects and has extremely high strength.
Therefore, it has high strength, high modulus of elasticity, high hardness, excellent heat resistance and corrosion resistance.
It is used as reinforcement materials for ceramics, metal and plastics composites.
1. When it is used as a reinforcement material for composite materials, its high aspect ratio improves those mechanical properties.
2. It is chemically stable and excellent in thermal conductivity.
3. Since it is non-eluting, it can be used for fluororesin and ceramics which contact with food directly.
4. It can be dispersed in water, so it is available for fluorine resin emulsion.
5. It has very high dielectric constant and loss tangent.
• Reinforcement materials for hard ceramics used in cutting tools
