SILICON NITRIDE BONDED SILICON CARBIDE PRODUCTSNozzle

 Use principle: The nozzle of SIN combined with SIC are mainly used for wet wet flue gas desul-furization (referred as FGD) industry. As a component of wet FGD desulfurization, it can make lime slurry spray by the certain flow, angle and granularity so that the gas power station boiler burned containing HF, SO2 and NO2 can occur the physical and chemical reaction, and the main product of gypsum can be used for building materials . After eliminating sulfur clean gas can be directly discharged into the atmosphere, so as to realize environmental protection.

The silicon carbide material lift tube

used for low pressure casting machinein liquid aluminum from heat preservation box into the upper wheel cavity, also used in other non-ferrous metal solution delivery. The silicon carbide material lift tube we provide with high intensity, smooth surface, not glued aluminum, good air tightness, not on casting blowholes lack of restriction.

C、SiC pressureless sintered Ceramics (SSiC)

SiC Armor plate

High density,  strong hardness, good Bending strength and lower cost  providing armor protection with tank, land vehicles, and body of military and police.
