Silica is used in the manufacture of flat glass, glass, foundry sand, glass fiber, ceramic glaze, blasting for rust prevention, sand for filtration, flux, refractory and lightweight concrete. Silica is widely used. Crystals that are rare in nature can be used to make important parts, optical instruments and crafts in the electronics industry. Silica is an important raw material for the manufacture of optical Fibers. generally quartz a ɛho tew betumi ayɛ quartz glass. quartz glass wɔ ntrɛwmu nsusuwii ketewaa bi, a ɛne ahwehwɛ a ɛyɛ mmerɛw 1/18 yɛ pɛ{7}} a ebetumi agyina ɔhyew a ano yɛ den ano na ɛwɔ acid a ɛyɛ papa a ɛko tia (gye HF). enti wɔtaa de quartz ahwehwɛ di dwuma de gyina hɔ ma quartz a wɔde yɛ nneɛma a wɔde yɛ nneɛma a wɔde yɛ nneɛma a wɔde yɛ nneɛma a wɔde yɛ nneɛma a wɔde yɛ nneɛma a wɔde yɛ adwuma Nneɛma a ɛwɔ hɔ.
