Silicon Nitride (Si3N4) is a relatively costly, high-temperature, structural ceramic
used where heat resistance, hardness, and strength are a premium.
It is very hard, and therefore can be used in high wear applications or applications requiring a fine surface polish.
Silicon Nitride is fabricated using either sintering, reaction bonding, hot pressing, or hot isostatic pressing.
The material properties resulting from these processes vary considerably.
Silicon nitride ceramic rod, is wear resistant, anti-corrosion, resistant to high temperature, and can endure impact. Silicon nitride ceramic rod has a service life about 7~10 times longer than metal rod. As critical part in rod pump, silicon nitride ceramic rod is widely used in electrical industry, ceramic industry, oil industry, food industry, medical industry, chemical industry etc. to replace metal rod.
