Silica is usually exploited by quarrying and it is rare for it to be extracted by underground mining. Physical and Chemical Properties. The three major forms of crystalline silica -quartz, tridymite and cristobalite- are stable at different temperatures and have subdivisions. For instance, geologists distinguish between alpha and beta quartz.

Silica, often referred to as quartz, is a very common mineral. It is found in many materials common on construction and oil & gas sites, including soil, sand, concrete, masonry, rock, granite, and landscaping materials. The dust created by cutting, grinding, drilling or otherwise disturbing these materials can contain crystalline silica particles.

When we talk about silica exposure we are talking about crystalline silica or quartz. Construction workers could be exposed to silica when cutting, grinding, drilling, sanding, mixing, or demolishing materials containing silica. The size of the airborne silica particles determines the amount of risk.

Different forms are also used as gemstones. Because it is a primary ingredient in sand it is also used to make glass & labware, silica brick, cement, and mortar. Ground quartz is used as an abrasive in stonecutting, sandblasting, and glass grinding. Powdered quartz is used in making porcelain, scouring soaps, sandpaper, and wood fillers.

Also, these materials are very fragile and extremely easy to chip or break. Imagine that many tiny hammers are breaking quartz glass little by little. That is what machining fused silica glass with diamond grinding tool is like. Machining it generates a numerous number of micro-cracks.
