About Fused Silica Mesh 325

PRATAP CORPORATION Fused silica is a form of silicon dioxide (SiO2) produced by melting high-purity crystalline silica, like quartz, and forming an amorphous, synthetic glass. Its characterized by very low thermal expansion and high thermal shock resistance, making it suitable for various applications, including optics and high-temperature ceramics

Exceptional Thermal and Chemical Stability

Fused Silica Mesh 325 offers superior resistance to thermal shock, extreme temperatures, and most chemicals due to its ultra-low thermal expansion and high purity. This makes it highly reliable for use in ceramics, refractories, glass manufacturing, and advanced electronics where stability and precision are required under intense conditions.

Versatile Industrial Applications

The product finds critical applications across multiple industriesincluding ceramics, precision castings, laboratory crucibles, refractory linings, and electronics. Its unique combination of high melting point, translucency to opacity, and inertness ensures optimal performance whether used for sophisticated optical components or rugged industrial processing.

High Purity for Advanced Manufacturing

With a purity greater than 99.9% SiO2, Fused Silica Mesh 325 supports advanced technological applications requiring extremely low impurity levels. Its consistent quality, verified by ISO 9001 standards, guarantees reliability and enhances the performance of sensitive products in research, medical, and optical sectors.
