【 摘 要 】

Glass ionomer cementsare glass and polymer composite materials. These materials currently find usein dentistry. The purpose of this work is to obtain glass powders based on thecomposition 4.5SiO2 – 3Al2O3 – 2CaOto be used in dentistry. The powders were prepared by a chemical route at 7000C. The properties of glass ionomer cements obtained from powdersprepared at 700 ºC were studied. Diametral tensile strength and microhardnesswere evaluated for the experimental glass ionomer cements and a commercial material.It was concluded that the properties of experimental cements were similar tothose of the commercial ones.
