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 […]
