Combining very high purity with outstanding high temperature properties, Momentive’s fused quartz tubing is an excellent candidate to consider for use in furnaces for processing silicon wafers. Semiconductor quartz tubing is developed to tolerate the various thermal gradients and high temperature extremes of the semiconductor manufacturing process. High purity and tight dimensional control of fused

At first glance, quartz crystals and glass can look like identical stones. There are notable differences in their internal structural composition, but it takes lab equipment and analysis not available to the average person to differentiate the two materials on this basis. Fortunately, there are other ways to determine whether a stone is quartz crystal

Quartz and rock crystal are both abundant minerals found throughout the world in the Earth’s crust. According to Mindat.org, “Quartz is the most common mineral found on the Earth’s surface.” Quartz and rock crystal are composed of silicon dioxide and are found as components within many different types of rocks. Quartz There are dozens of

What is Quartz? Quartz is a chemical compound consisting of one part silicon and two parts oxygen. It is silicon dioxide (SiO2). It is the most abundant mineral found at Earth’s surface, and its unique properties make it one of the most useful natural substances. Rock crystal quartz: Transparent “rock crystal” quartz. This specimen shows the conchoidal fracture
