About Fused Silica Mesh 10/20

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 Stability

With a maximum service temperature of 1700C and a low thermal expansion coefficient (0.55 x 10 /C), Fused Silica Mesh 10/20 is ideal for environments facing rapid temperature fluctuations. This property ensures reliable performance in high-temperature processes found in refractories, glass, and ceramic applications, minimizing risk of cracking or deformation under thermal stress.

Versatile Industrial Applications

Fused Silica Mesh 10/20 finds extensive use as an industrial raw material across diverse sectors including foundries, electronics, photovoltaics, and sandblasting. Its high purity and chemical inertness make it perfect for producing precision components, casting molds, and as a filler in specialized glass and ceramic products. Its angular granule shape provides reliable mechanical performance in demanding tasks.

Safe and Environment-Friendly

This mesh is non-poisonous, odorless, and free from radioactivity, ensuring safety for handling and environmentally conscious manufacturing. Its insolubility in water and neutral pH (7) prevent contamination of processes, while its adherence to GB/T 24566-2009 standards guarantees quality and consistency for exporters, suppliers, and manufacturers alike.

FAQs of Fused Silica Mesh 10/20:

Q: How is Fused Silica Mesh 10/20 used in industrial applications?
