Silica exists in both crystalline and amorphous (noncrystalline) forms. Conversion from amorphous to crystalline form can occur at high heat. Quartz is the most common form of crystalline silica and the most commonly used industrially. Cristobalite also has important industrial uses.
Breathing sharp, freshlycut sand dust, such as silica at sand mining and processing sites, carries a greater risk of pulmonary disease than breathing older, smoother particles weathered by heat, wind, and moisture – such as silica dust blown from cropland. There is no federal standard for ambient air exposure to silica outside the workplace.
