粉煤灰制备耐火材料最佳烧结温度的探究
Exploration of Optimal Sintering Tempertature in the Preparation from Refractory Material of Fly Ash
摘要
Abstract
Fly ash based refractory materialsas were prepared using fly ash(from a coal power plant in Anning City) as the main raw material and sludge and industrial alumina the auxiliary materials.viability of their industrial application was analyzed theoretically.The microstructure was analyzed using X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques.On the basis of meeting the national standard ,we tried to explore the best sintering temperature range.The results show that at sintering temperature of 1300 ℃ and fly ash content of 68%,the incorporation,porosity,water absorption,compressive strength,flexural strength,refractoriness,permanent heating of the product meets the national standard.XRD results indicate that the higher the sintering temperature (1100-1300 ℃),the more and stronger the mullite peaks became.SEM results show that when the sintering temperature is increased from 1100 ℃ to 1300 ℃,the dominant shape of mullite shifted from neddle to columnar.At the temperature of 1300 ℃,dense mullite structure is observed.In comparison,when the sintering temperature is 1400 ℃,less columnar in loose mullite structure is found.关键词
