High purity fused silica (99.98% amorphous)
Available in both flour and grain forms
Versatile material for use in refractory application
Available in both standard and custom particle sizes distributions
Dinglong fused silica is designed for optimal thermal shock resistance, insulating properties, and a low coefficient of thermal expansion. Our fused silica performs excellently in refractory applications that require dimensional stability and where heat retention is needed.
In investment casting, fused silica is used for its volume stability. Indeed, fused silica has an extremely low thermal expansion coefficient and so very tight tolerance castings can be produced with easy shell removal.
Our fused silica has very high electrical resistivity and low thermal conductivity, so is used as filler in epoxy molding compounds for semi-conductors.
Dinglong manufactures a wide range of fused silica products and specific product grades, including refractory application grade, electronics grade, foundry grade. All fused silica products are produced under carefully controlled conditions and are optimized for consistency and reliability in order to allow our customer to make products with high purity and a degree of dimensional accuracy.
Dinglong fused silica are available in both flour and grain forms. We offer both standard and custom particle size distributions. Our experts will work with you to optimize your application. Dinglong fused silica products are available in 2,200 lbs. (1,000 kg) tote sacks.
