形态

Fine white powder with particle sizes generally below 1mm. This is not the same as the commercial products “fumes silica,” “silica gel,” “precipitated silica,” or “fused silica.” It is formed during the electric arc production of elemental silicon from quartz, which is reduced to silicon monoxide, escaping from the furnace and oxidized by air to silicon dioxide. This condenses to form spherical particles. For the production of ferrosilicon, iron metal is added to the charge; during charging there is also exposure to crystalline silica.

简介

微硅粉，又叫硅微粉，也叫硅灰、硅粉或二氧化硅超细粉。微硅粉是冶金电炉在2000℃以上高温时产生的SiO2和Si气体与空气中的氧气迅速氧化并冷凝而形成的一种超细硅质粉体材料。
