High purity fused quartz frits/porous sintered filters/fused glass discs/quartz glass sinters of our company are made of high purity fused quartz sand with SiO 2 content > 99.99% and high temperature resistance up to 1400 ℃. Then it has uniform porosity and is durable. It is widely used in various scientific research institutions, university laboratories and other related industrial fields. We are able to produce all kinds of fused quartz frits with different porosity (G00 to G5), sizes and shapes (round, square, cylindrical) according to your individual requirements. Also, depending on our ability to produce other types of quartz glass products, we would integrate quartz frits into other quartz glass instruments as a complete product to help our end customers solve their application problems.
Approximate application of various porosity
G00(250-550μm) : liquid and gas filtration.
G0(160-250μm) : gas filtration, gas shunting in liquid under low pressure, filtration of very coarse sediment.
G1(100-160μm) : coarse filtration, coarse sediment filtration, gas filtration in liquid, slow flow of liquid, filtration of coarse gas, used for making coarse mineral extraction device, and gel filtration substrate with loose filter layer.
G2(40-100μm) : pre fine filtration, used for preparation of crystalline sediment, mercury filtration.
G3(16-40μm) : analytical filtration, analysis of medium and fine precipitates, preparation of fine precipitates, cellulose chemical filtration, fine gas filtration, fine mineral extraction device.
G4(10-16μm) : fine filtration, analysis of very fine sediment (e.g. BaSO4, Cu2O), analysis of sediment with appropriate fineness, mercury check valve and stop valve.
G5(5-10μm) : Used for the analysis of ultra-fine substances. It is usually close to the effect of G4.
