Abstract
In this article,a kind of porosity ceramics was prepared using copper ore tailings and potassium feldspar with adding CaCO3 as the pore-forming materials.The effects of sintering temperature on the crystallization phase,shore hard-ness,density,water absorption of the porosity ceramics were investigated systematically.The results indicate that the main crystalline phases of the porosity ceramics are leucite,wollastonite and akermanite.The increasing temperature favors the formation of leucite.The hardness of the porosity ceramics drops with the rise of temperature when the temperature above 1 160 ℃.The density of the porosity ceramics exhibits rather temperature independent behaviors in the range of 1 150 ℃ to 1 180 ℃.However,it changes obviously when further raising the temperature.For the porous ceramics with different con-tent of copper ore tailings,the water absorption reaches maximum at 1 180 ℃.关键词
