Silicon Nitride Ceramic

 Silicon Nitride Ceramics

Silicon nitride is a synthetic, high-performance material.  Due to excellent performance, it is widely used in some high-reliability occasions. Shengde company is bringing all kinds of high-quality and cost-effective silicon nitride ceramics, including:

1. Silicon Nitride Insulating Ring

The insulating ring is one of the consumables for the polysilicon reduction furnace. Compared with the traditional quartz insulating ring, the silicon nitride insulating ring has better  high-temperature performance, multiples of service life, and higher cost performance, quickly and directly reducing the production cost of polysilicon. It is currently used by more polysilicon manufacturers with technical and scale advantages, and is currently the best alternative   product for the quartz insulating ring.

2. Silicon Nitride Structural Parts

Since silicon nitride has strong resistance to acid and alkaline corrosion; excellent high-temperature resistance, lower thermal expansion coefficient, non-magnetic property, electrical insulation, and low thermal conductivity, the structural components made are widely used in aviation, aerospace, military oilfield, various chemicals, high-temperature metallurgy, new energy, high-speed and load locomotives, electronics and other fields. Our company can process and manufacture various shapes of high-quality silicon nitride structural components according to customer drawings .

3. Silicon Nitride Ceramic Balls and Bearings

Because silicon nitride balls have good wear resistance, high strength, high stiffness, self-lubricating and other excellent performance, as well as resistance to acid and alkaline corrosion, resistance to high temperature, a small specific gravity, non-magnetic property, electrical insulation, and a series of other properties, they  have becomethe preferred materials for high-grade ceramic bearings.

Similarly silicon nitride bearings have high-temperature resistance, corrosion resistance, wear resistance, oilless self-lubricating, anti-magnetic, insulation, high-speed and other features. They are widely used in aviation, aerospace, military, petroleum, chemical, metallurgy, automobiles, electricity, medical equipment and other extremely harsh environments and conditions.
