Silica dust | Cancer Council

Silica dust (crystalline silica) is found in some stone, rock, sand, gravel and clay. The most common form is quartz. Silica dust can also be found in the following products: bricks; tiles; concrete; some plastic material. When these materials are worked on, silica is released as a fine dust known as respirable crystalline silica or silica dust.
