CIP forming，GPS sentering，precision machining，stable quality.
Size and precision are according to customization.
1. High corrosion resistance, this means they can be also used in strong acid、strong alkali except HF .
2. High temperature resistance. Si3N4 ceramic balls can still retain the strength and hardness even the temperature comes to 1000 ℃.In reducing atmosphere it can be used up to 1500 ℃.
3. Electrical insulation、non-magnetic.
4. Low density(3.26 g/cm3), high rigidity,high strength,high hardness.
5. Low coefficient of thermal expansion(3.2×10-6/K), it is nearly 1/4 of the chrome steel, which leads to a good thermal shock resistance of Si3N4 ceramic.
