Product Description

Product Description

Silicon nitride ceramic balls
 
Silicon nitride (Si3N4) is the main material of these balls. They have excellent mechanical properties. They possess high hardness, second only to some super - hard materials like diamond and cubic boron nitride. This hardness enables them to withstand heavy loads and high - pressure environments.
 

silicon nitride ceramic balls have good wear resistance. They can maintain their spherical shape and surface quality even after long - term use and friction, which makes them ideal for applications in precision machinery and bearings. They also have a relatively low density compared to metallic materials, which helps in reducing the overall weight of the equipment in which they are used.

These ceramic balls have good corrosion resistance, being able to resist the corrosion of many chemicals, acids, and alkalis. Their high - temperature stability is another advantage. They can maintain their physical and chemical properties at relatively high temperatures, making them suitable for use in high - temperature working conditions such as in some industrial furnaces and high - speed rotating equipment.
