Read More2021-8-16 What is silica dust? Silica is a common naturally occurring mineral, also known as silicon dioxide. Silica can be found or manufactured in different forms, broadly divided into crystalline and non-crystalline (amorphous). The most common form of silica is quartz. Silica is found in some stones, rocks, sand, gravel and clay.
