摘　　要：对粉煤灰负离子功能微晶玻璃体系性能进行了研究,通过正交试验确定了该体系的优化配合比为粉煤灰:电气石∶钛白粉∶河沙∶石灰=20∶18∶1∶26∶15,该微晶玻璃体系经过930℃核化60 min,1085℃晶化50 min处理后,密度达2.70 g/cm3、抗压强度达27.76 MPa、弯曲强度达18.18 MPa、耐碱性为0.06%、耐酸性为0.16%,负离子释放量达694 ions。The properties of glass-ceramics prepared by using fly ash as mjor raw material and generating negative air ions spontaneously have been studied in this paper.Orthogonal experiment was adopted to get an optimum mix design, fly ash ： tourmaline ： TiO2 ： sand ： lime equal to 20 ： 18 ： 1 ： 26 ： 15. The glass-ceramics was sintered at nucleation temperature 930 ℃ , nuclaetion time 60 min, crystallization temperature 1085 ℃, crystallization time 50rain. The analyses show that the density is 2.70 g/cm3, the compressive strength is 27.75 MPa, the bending strength is 18.18 MPa, the alkali resistance is 0.12% and the acid resistance is 0.15% and the the negative air ions is 594 ions.
