Product Description

Silicon Nitride Ceramic Ball:

Silicon Nitride Ceramic Ball is made of the hot isostatic pressing and sintering furnace and has the properties  including high strength,high wear resistance,high temperature,corrosion,acid and alkali resistant,long-term using in the sea,good electrical insulating ect.

 

The precision Si3N4 Ceramic Ball of Innnovacera produce is widely used in a  a variety of high-precision, high-speed / ultra-high-speed bearings, vacuumbearing, high / low temperature bearing, non-magnetic bearing.It is also as the measurement ball  used in chemical valve,high temperature valve,meter valve ect.The field of the application involve chemical, metallurgical, medical, food, oil, electronics,aerospace,ect.

* Fine crystalline Never rust,
* Can roll without oil or grease,
* Excellent corrosion resistance withstands attack from harsh chemicals and demanding environmental conditions,
* Lightweight: Silicon Nitride weighs 60% less than steel which reduces centrifugal force, skidding,
* Wear under high speed and acceleration.

 

 

 

Features:
* High hardness
* Wear resistance and corrosion resistance
* Antimagnetic electricity
* Solve the pollution problem of other grinding media materials on the product, ensuring purity and quality
* Long service life and operating costs

 

Application:
>Equipment such as ball mills, stirring mills, and vibration mills used in laboratories and production lines.
>Fields such as crushing, grinding, or dispersing advanced ceramic powder materials, magnetic materials, non-metallic mineral materials, and pyrotechnic materials.
>Ultra fine dispersion of high-end materials, especially in working conditions with extremelyhigh requirements for product purity and fineness.
