The ceramic membrane can be made of various inorganic materials. However, the solid and durable material silicon carbide also represents its chemical style SiC, which appeared quickly because it has some unique advantages over traditional ceramics and polymer membranes. Let's take an in-depth look at silicon carbide and the unique benefits this material offers.
Silicon carbide is a synthetic crystalline compound containing pure silicon and pure carbon. Silicon carbide is the second hardest material in the world, after diamonds, and the hardest man-made material in history. 1-10 In the Mohs hardness tester, which measures the hardness of minerals, the material is produced for the first time and attempts are made to make artificial diamonds.
More recently, the element has discovered ceramic membranes for liquid filtration, which provide a porous support structure through which filtered water can penetrate. The thermal and mechanical stability of SiC is critical for many industrial applications, especially where frequent cleaning or sterilization is required. The use of this durable material can ensure a high-quality product with a long service life and some unique advantages.
A special coating is placed in the flow channel of the ceramic membrane to achieve all the effects of the SiC ceramic membrane. This unique coating material also contains silicon carbide material, which is dried and then sintered at high temperature in an inert atmosphere. This unique coating makes the membrane strong and durable, but also determines the flow channel pore size and water flux of the membrane.
