石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)是(shi)一種(zhong)只含二氧化硅單一成份的玻(bo)(bo)(bo)(bo)璃(li)(li)(li)。由于種(zhong)類、工(gong)藝、原料的不同，國外(wai)(wai)常(chang)常(chang)叫做硅酸玻(bo)(bo)(bo)(bo)璃(li)(li)(li)、石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)、熔融(rong)石(shi)(shi)(shi)英(ying)(ying)(ying)、熔凝石(shi)(shi)(shi)英(ying)(ying)(ying)、合成熔融(rong)石(shi)(shi)(shi)英(ying)(ying)(ying)，以及沒(mei)有明(ming)(ming)(ming)確概念的透(tou)(tou)明(ming)(ming)(ming)、半透(tou)(tou)明(ming)(ming)(ming)、不透(tou)(tou)明(ming)(ming)(ming)石(shi)(shi)(shi)英(ying)(ying)(ying)等。我國統稱(cheng)石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)，多按工(gong)藝方(fang)法(fa)、用途及外(wai)(wai)觀來(lai)分類，如(ru)電熔透(tou)(tou)明(ming)(ming)(ming)石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)、連熔石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)、氣煉透(tou)(tou)明(ming)(ming)(ming)石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)、合成石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)、不透(tou)(tou)明(ming)(ming)(ming)石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)、光學(xue)石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)、半導體用石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)、電光源用石(shi)(shi)(shi)英(ying)(ying)(ying)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)等。

石(shi)英容量(liang)瓶石(shi)英玻(bo)璃(li)是以含(han)二氧化硅(gui)物質，如水晶、硅(gui)石(shi)。四氧化硅(gui)為(wei)原料高(gao)溫熔制而(er)成。其(qi)二氧化硅(gui)含(han)量(liang)比普通玻(bo)璃(li)高(gao)得多(duo)，一(yi)般石(shi)英玻(bo)璃(li)二氧化硅(gui)含(han)量(liang)在99.999%。石(shi)英玻(bo)璃(li)具(ju)有(you)優異(yi)的(de)光(guang)學性能，不僅可(ke)見光(guang)透(tou)(tou)光(guang)度特別(bie)好，而(er)且(qie)透(tou)(tou)紫外(wai)線，紅外(wai)線。
