| 硅质岩用途 Use of siliceous rocks 硅质岩有多种工业用途。如燧石以其硬度大，可作为研磨原料和硅质耐火材料;碧玉也以坚硬致密和色泽美丽作为细工石料。硅藻土因具有强烈的吸附性在日用化工、制糖业和净水工业等多种部门中都有广泛的用途。火山活动可提高海洋中的硅质含量，也是硅质岩中硅的主要物源。 Silicate has many industrial uses. For example, flint can be used as abrasive material and silica refractory because of its high hardness; Jasper also uses hard, compact and beautiful color as fine stone. Diatomite is widely used in daily chemical industry, sugar industry and water purification industry because of its strong adsorption. Volcanic activity can increase the content of silica in the ocean, and is also the main source of silica in siliceous rocks. |
