Product Description

Silicon Nitride Ceramic Disc Plate

Silicon Nitride (Si3N4) is 60% lighter than steel but strong enough to survive some of the most demanding applications in a variety of industries. This lightweight, high-strength ceramic material is used as an alternative to stainless steel, super alloys, tungsten carbides and first-generation ceramics such as Al2O3 and ZrO2. It offers excellent thermal shock resistance and high fracture toughness, compatibility with nonferrous metal melts, and improved structural reliability compared to other ceramic materials

 

Silicon Nitride (Si3N4) Characteristics:

1.Good thermal shock resistance

2.Creep resistance

3.Low density

4.High fracture toughness

5.High hardness and wear resistance

6.High wear resistance and corrosion resistance .

7.High temperature resistance

8.Good flexural strength and high fracture toughness

9.Very good thermal shock resistance

10.Dimensional stability and aging resistance
 

Silicon Nitride Ceramic Use:

.Rotating bearing balls and rollers

.Cutting tools

.Engine moving parts - valves, turbocharger rotors

.Engine wear parts - cam followers, tappet shims

.Turbine blades, vanes, buckets

.Metal tube forming rolls and dies

.Precision shafts and axles in high wear environments

.Weld positioners
