So what is quartzite? It's basically sandstone that has been compressed and squeezed under tremendous pressure and high temperatures (metamorphism) until the individual crystals of sand plus the silica cement that bound them together as sandstone are recrystallized to make a new kind of super-solid crystalline stone.

Silica can be said synonym of SiO2 (Silicon dioxide), it is present on earth as sand naturally in pure form. Silica is available in both crystalline and amorphous forms. These are fine sized grains. Whereas the Quartz is bigger and rough. Quartz also consists of silicon dioxide, but silica is pure form and quartz may have other minerals.

Quartz is a major component of rock and sand. Quartz is brought into most construction materials by sand. When quartz is present in construction dust, the workers protection plan should be re-evaluated. LCS laboratory uses a modified method of NIOSH 7602 for silica testing, and requires 1-2 grams of material preferably in the form of fine dust.
