摘要：Silicon Dioxide is a natural combination of silicon and oxygen found largely in sand. Silicosis is a long-term progressive lung damage caused by fine particle silica dust from quartz rock (NCI04 ). Silica is another name for the chemical molecule SiO2 , or silicon dioxide, which is made up of silicon and oxygen. Silica comes in a variety of forms. The chemical content of all silica forms is the same, but the atom configurations change. There are two types of silica compounds: crystalline (or c-silica) and amorphous (or a-silica) (a-silica or non-crystalline silica). The structures of c-Silica compounds feature silicon and oxygen repeating motifs. When compared to c-silica, a-silica chemical structures are more haphazardly connected. Silica is a colourless, odourless material made up of silicon and oxygen atoms. Silica particles float in the air, forming non-explosive dusts. Silica may generate silicates when it reacts with other metals and oxides.
