Silicate glass and dental product
The present invention provides: a silicate glass which is capable of suppressing color change of zirconia even if the silicate glass is fired together with an unsintered zirconia at the same time, said zirconia serving as a base material; and a dental product which uses this silicate glass. The present invention relates to: a silicate glass which contains 65.0-90.0 mol% of SiO2, 4.0-15.0 mol% of Al2O3, 1.0-10.0 mol% of K2O, 0.1-7.0 mol% of Na2O and 0.01-15.0 mol% of CaO, while substantially containing no B2O3, and wherein (number of moles of Al2O3)/(total number of moles of RO and R2O) is 0.70or more, with R in the metal oxide represented by RO being a group 2 or group 12 metal element of the periodic table, and with R in the metal oxide represented by R2O being a group 1 metal element ofthe periodic table; a composite body which contains this silicate glass and a base material that is composed of a ceramic; a sintered body which is obtained by firing this composite body; and a dental product which is composed of this sintered body.
本发明提供即使与氧化锆未烧结体同时煅烧也能够抑制作为基材的氧化锆的色调的变化的硅酸盐玻璃、和使用其的牙科用产品。本发明涉及：硅酸盐玻璃，其包含65.0~90.0mol%的SiO、4.0~15.0mol%的AlO、1.0~10.0mol%的KO、0.1~7.0mol%的NaO、和0.01~15.0mol%的CaO，实质上不含BO，{(AlO的摩尔数)/(RO+RO的总计摩尔数)}为0.70以上，前述RO所示的金属氧化物的R表示周期表的第2族或第12族的金属元素，RO所示的金属氧化物的R表示周期表的第1族的金属元素；复合体，其含有该硅酸盐玻璃和包含陶瓷的基材：将该复合体煅烧而得到的烧结体；和包含该烧结体的牙科用产品。
