石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)璃(li)是一種只含二氧化硅單一成(cheng)份的(de)玻(bo)璃(li)。由于種類、工藝、原料的(de)不同，國外(wai)常常叫做硅酸玻(bo)璃(li)、石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)璃(li)、熔(rong)(rong)融(rong)石(shi)(shi)(shi)英(ying)(ying)(ying)、熔(rong)(rong)凝石(shi)(shi)(shi)英(ying)(ying)(ying)、合成(cheng)熔(rong)(rong)融(rong)石(shi)(shi)(shi)英(ying)(ying)(ying)，以及(ji)沒有(you)明(ming)確概念的(de)透(tou)(tou)明(ming)、半透(tou)(tou)明(ming)、不透(tou)(tou)明(ming)石(shi)(shi)(shi)英(ying)(ying)(ying)等。我國統(tong)稱石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)璃(li)，多按工藝方法、用(yong)途及(ji)外(wai)觀來分類，如(ru)電熔(rong)(rong)透(tou)(tou)明(ming)石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)璃(li)、連熔(rong)(rong)石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)璃(li)、氣煉透(tou)(tou)明(ming)石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)璃(li)、合成(cheng)石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)璃(li)、不透(tou)(tou)明(ming)石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)璃(li)、光(guang)學(xue)石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)璃(li)、半導體用(yong)石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)璃(li)、電光(guang)源用(yong)石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)璃(li)等。人們(men)習慣于用(yong)“石(shi)(shi)(shi)英(ying)(ying)(ying)”這樣一個簡(jian)

石(shi)英(ying)(ying)玻(bo)璃是以含二氧化硅(gui)物質(zhi)，如水晶(jing)、硅(gui)石(shi)。四氧化硅(gui)為原料高(gao)溫熔制而成。其二氧化硅(gui)含量(liang)比普通玻(bo)璃高(gao)得多，一(yi)般石(shi)英(ying)(ying)玻(bo)璃二氧化硅(gui)含量(liang)在99.999%。石(shi)英(ying)(ying)玻(bo)璃具有優異的光學性能，不僅可見光透光度特別好，而且透紫外線，紅外線。
