Reinforcing glass fibers of MgO-CaO-ZnO-Al2 O3 -SiO2 -TiO2

摘要: Glass fibers of superior physical properties are produced by drawing at a temperature between about 1200° and 1300° C melt consisting essentially MgO-CaO-ZnO-Al2 O3 -SiO2 -TiO2 the following approximate molar composition: ______________________________________ MgO 7-27.5 %CaO 4.5-32.5 %ZnO 3-15 %Al2 5-13.5 %SiO2 36-56 %TiO2 0- 9 %______________________________________ The especially suited for use as reinforcement in plastic, plaster, cement or low-melting metal structure.
