SiC Ceramic Membrane

Description

Silicon carbide membrane (SIC) is made by high-temperature sintering using recrystallization technology. Its porous support layer, transition layer, and membrane layer are all silicon carbide materials. Its filtration precision is microfiltration and ultrafiltration. The SIC membrane filtration system is a fluid separation process in the form of "cross-flow filtration". The raw material liquid flows at high speed in the membrane tube. Under the pressure drive, the clarified permeate containing small molecular components penetrates outward through the dense layer of the membrane in the vertical direction. The turbid concentrated liquid containing macromolecular components is intercepted, thereby achieving the purpose of clarification, separation, concentration and purification of the fluid.

Raw Material: Silicon Carbide

Alternate name of SiC is Corundum or Moissanite, including black SiC and Green SiC. SiC crystal has two kinds of structures which are α-SiC & β-SiC. SiC material has features of stable chemical properties, high coefficient thermal conductivity, low coefficient of thermal expansion, excellent abrasion resistance performance, Moh's hardness 9.5 grade (only a little lower than diamond), high

temperature resistance, oxidation resistance. SiC is raw material of refractory, abrasive, metallurgy, photovoltaic industry.

Silicon Carbide Membrane

SiC Ceramic Microfiltration & Ultrafiltration Membrane is sintered through recrystallization technique in high temperature of 2400℃. The raw material Silicon Carbide have features of high hardness and high strength.
