Method for preparing microcrystalline glass by using CRT cone glass

The invention provides a method for preparing microcrystalline glass by using CRT cone glass, and belongs to the field of treatment and high-value utilization of dangerous solid waste resources. The method comprises the following steps: carrying out vacuum melting on a mixture of CRT cone glass and mineral, and removing lead oxide to obtain residues, wherein the mineral is red mud or kaolin; subjecting the residues to compression molding, and obtaining a blank; and carrying out normal-pressure sintering on the blank to obtain the microcrystalline glass. According to the method for preparing the microcrystalline glass from the CRT cone glass, waste is treated with waste, and meanwhile reutilization of residual silicate in the vacuum melting process is achieved. 本发明提供了一种利用CRT锥玻璃制备微晶玻璃的方法，属于危险固废资源的处置与高值化利用领域。本发明的方法包括以下步骤：将CRT锥玻璃与矿物的混合料进行真空熔炼，脱除氧化铅，得到残余物；所述矿物为赤泥或高岭土；将所述残余物进行模压成型，得到坯料；将所述坯料进行常压烧结，得到微晶玻璃。本发明利用CRT锥玻璃制备微晶玻璃的方法，实现了以废治废，同时实现了真空熔炼过程中残余硅酸盐的再利用。
