What Is High Purity Quartz Sand Used for and How to Get It?

By

High purity quartz sand (HPQ), typically containing SiO₂ ≥99.99% (commonly 99.997%–99.999%, or even higher), is characterized by extremely low impurity levels (especially Al, Fe, Ti, B, P, etc.), typically controlled at ppb or even sub-ppb levels. Even trace contamination can render the end products completely ineffective. Due to these characteristics, it has become one of […]

How to Prepare High-Sphericity Silica Micro-powder from Quartz Powder?

By

High-sphericity silica micro-powder (sphericity ≥ 0.95, often called spherical SiO₂) is an essential functional powder in advanced fields such as 5G substrates, copper-clad laminates (CCL), EMC epoxy molding compounds, silicone adhesives, and thermal interface materials. Traditional quartz powder produced by mechanical crushing has irregular angular shapes. Direct use leads to high system viscosity, low filling

Fused Silica

What is Fused Silica? What are the Applications of Fused Silica?

By

In the fields of semiconductors, optics, aerospace, and high-end ceramics, there is a material often referred to as the “most expensive sand”—fused silica. It is not just ordinary quartz sand that is melted and cooled. It is the purest, most stable form of amorphous silica (SiO₂>99.999%) that can be industrially produced. Fused silica is nearly
