"Vitreous silica" is a particular form of amorphous silica, much neglected in experimental studies on silica toxicity. In spite of the incorrect term "quartz glass", often employed, this material is fully amorphous. When reduced in powdered form by grinding, the particulate appears most close to workplace quartz dust but, opposite to quartz, is not crystalline. As silicosis and lung cancer are also found among workers exposed to "quartz glass", the question arises of whether crystallinity is… CONTINUE READING
