Silicon Carbide Ceramic
The perfect material for corrosive environment
Silicon carbide ceramic (SiC) is an advanced ceramic material containing silicon and carbon. It occurs in nature as the extremely rare mineral moissanite.
Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics.

Corrosion Resistance
A more cost-effective solution compare to Titanium
The corrosion resistance of our ceramic structured packing is better than that of various stainless steel and titanium materials. In general, through increasing Cr and Mo elements in stainless steel results in an increased the stability, but in the environment with organic solvents, the corrosion of stainless steel can be accelerated to 10 times faster. This significantly reduces the service life of stainless steel packing to as short as 4 months in some cases.
Titanium structured packing is somtimes recommended for corrosive environment, however because of its high prices, it is difficult to be economically viable for most refineries.
In contrast, Standard Ceramic's SiC structured packing is able to withstand the corrosion of any concentrated sulfuric acid, hydrochloric acid and hydrofluoric acid. The SiC structured packing is 10-20 times more resistant than titanium alloys.
