Following a new study linking quartz countertops to silicosis, California is considering banning the engineered stone. Quartz countertops, a staple in many high-end kitchens, are being linked to ...
Crystalline silica exists in seven different forms , depending upon the temperature of formation. The main three polymorphs are quartz, cristobalite, and tridymite. Quartz is the second most common mineral in the world (next to feldspar). [19] Microcrystalline silica consists of minute quartz crystals bonded together with amorphous silica.
In mineralogy, silica (silicon dioxide, SiO 2) is usually considered a silicate mineral rather than an oxide mineral. Silica is found in nature as the mineral quartz , and its polymorphs . On Earth, a wide variety of silicate minerals occur in an even wider range of combinations as a result of the processes that have been forming and re-working ...
As with any silica-containing stone, silicosis can result from breathing dust produced when cutting or processing engineered stone made with quartz. The risk of inhaling quartz dust can be mitigated by taking appropriate safety precautions. [10] [11] Risk of silicosis is high when little or no safety precautions or protective equipment are used ...
Whereas silica typically makes up less than 30% of natural stones like marble or granite, quartz contains around 90% or more, according to Jenny Houlroyd, an industrial hygienist at Georgia Tech ...
In California, dozens of workers with silicosis have lodged lawsuits against companies like Cambria and Caesarstone. Reyes Gonzalez is the first of them to go to trial, according to his attorneys.
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide).The atoms are linked in a continuous framework of SiO 4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2.
