Abstract

The invention discloses ferrochrome slag glass ceramics,and further provides a preparing method of the ferrochrome slag glass ceramics. The ferrochrome slag glass ceramics are prepared from,by mass,88-92% of ferrochrome slag,5-7% of fluxing agent,2.2-4.4% of clarifying agent and 0.5-1.5% of KOH. The preparing method of the ferrochrome slag glass ceramics comprises the following steps of mixing,heating and melting,moulding by casting,annealing,crystallization treatment and the like. The prepared ferrochrome slag glass ceramics have good abrasive resistance,erosion resistance and impact resistance performance,and the problems of environmental pollution,safety and the like of existing ferrochrome tailings are solved.

Description

technical field [0001] The invention relates to the technical field of glass-ceramic materials, in particular to a ferrochrome slag glass-ceramic and a preparation method thereof. Background technique [0002] Microcrystalline glass, also known as microcrystalline jade or ceramic glass, is a comprehensive glass and a new type of building material newly developed by foreign countries. Its scientific name is glass crystal. Glass-ceramic looks very different from our usual glass. It has the dual characteristics of glass and ceramics. The atomic arrangement inside ordinary glass is irregular, which is one of the reasons why glass is fragile. Glass-ceramic, like ceramics, is composed of crystals, that is to say, its atomic arrangement There are rules. Therefore, glass-ceramic is brighter than ceramics and tougher than glass, and its composition includes silicate. [0003] Tailings are one of the products of sorting operations in mineral processing. Among the products of this o...
