Dinglong Quartz Limited is a quartz material manufacturing company headquartered in Jiangsu China. Dinglong has been engaging in researching and producing fine quartz materials since 1987. The product range includes fused silica, fused quartz, quartz powder, quartz tube and quartz crucible. Dinglong’s quartz materials and products are nowadays widely used in refractory, electronics, solar, foundry and other special applications and are distributed within domestic markets and to overseas markets.
Fused silica is an extremely insulative material with very low thermal conductivity. With its high thermal shock resistance, it is often used in refractory applications, such as aluminum launders or highly cyclical applications.
In investment casting, fused silica is used for its volume stability. 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 it is often used in the electronics industry as filler in epoxy molding compounds for semi-conductors.
Through 30 years of establishment, Dinglong has acquired strong mechanical and technical support and accumulated tremendous experiences for producing fine quartz materials.
To provide quartz materials of superior quality and value is our mission. We believe reliable products can help us obtain leadership sales and build trust and friendship with our customers.
