Quartz frits porous glass filter disc is made of composing of bonded quartz glass sand. It has the same high purity SiO2 material as our fused quartz tubes or plates. Our company can manufacture any kinds of quartz porous glass filter disc by different size of quartz sand. Applications of fritted filter discs are in liquid or acid gas filtering of lab and other chemical use.
Fused Quartz Glass Features:
Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.
1. High temperature resistance. The softening point of fused quartz glass is about 1730℃ and can be used for long time working under 1100℃~1250℃. And working at 1450℃ in a short time.
2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature
3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to 1100℃ and putting it in normal temperature water will not crack.
4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.
5. The electrical insulation performance is good. Resistance value of quartz glass equaling to 10000 times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.
