Glass Composition and Crystallized Glass Composition Having Low Melting Temperature Using Fly Ash of Power Station, and Method for Making the Same

摘要

To the invention Sikkim heat-treated by the addition of low melting point glass composition, the crystallized glass composition and relates to a method of manufacturing the same, cost of CaO upset easy shells and a small amount of the crystal subject to the particular environmental pollutants coal ash using a thermal power plant fly ash high strength is obtained by crystallization having a wear-resistant glass and a process for their preparation.; The crystallized glass is 50 to 90 wt% of coal ash, comprising the steps of homogeneously mixing the baking process a clam shell 10 to 30% by weight and determined agent 5-11% by weight, removing the harmful gas and the mixture was calcined at 950 ℃ 1 car steps and, a step of forming the molten glass and the mixture of the harmful gas is removed by the secondary heating to 1400~1500 ℃, the third heat treatment for 30-240 minutes after the molten glass obtained in the vicinity of the maximum heat generation starting temperature of carried out is obtained by the method consisting of a step for obtaining crystallized glass.
