PREPARATION METHOD OF FA-TYPE GLASS CERAMIC USING FLY ASH AND WASTE GLASS

摘要

PURPOSE: A method for preparing glass ceramic is provided, to obtain an FA-type glass ceramic having improved mechanical strength by using fly ash and waste glass which are industrial waste. CONSTITUTION: The method comprises the steps of mixing waste glass and fly ash in the ratio of 4:1 by weight; milling the mixture with 700 rpm by using a disk-like ball mill for 4 hours to obtain a fine powder; and heating the fine powder in an electric furnace of 800 deg.C for 30 min to obtain glass ceramic.
