Pink aluminosilicate glass
A pink aluminosilicate glass, comprising: a glass former, a network intermediate oxide, a network modifier oxide, a network former oxide, a network modifier, a colorant and a clarificant, wherein the glass former is SiO 2 , the network modifier oxide is CaO, MgO, K 2 O and Na 2 O, the network former oxide is B 2 O 3 , and the network modifier is ZrO 2 and SrO. This glass is pink in visible light, has a good visual effect, and has a relatively high thermal stability, and can improve the usage safety in harsh working environments.
1. A pink aluminosilicate glass, comprising a glass former, a network intermediate oxide, a network modifier oxide, a network former oxide, a network modifier, a colorant, and a clarificant;
wherein:
a strain point of the pink aluminosilicate glass is greater than 550° C.;
the network modifier oxide is B 2 O 3 accounting for 0-10% by mass of the total mass of the glass, or the network modifier oxide comprises CaO accounting for 1-10% by mass of, MgO accounting for 1-5% by mass of, K 2 O accounting for 5-10% by mass of, and Na 2 O accounting for 1-10% by mass of the total mass of the glass;
the network modifier comprises ZrO 2 accounting for greater than 2.5% and less than 5% by mass of and SrO accounting for greater than 1% and less than 10% by mass of the total mass of the glass;
the colorant is Er 2 O 3 accounting for 0.2-3% by mass of the total mass of the glass;
the clarificant is a mixture of SnO and Na 2 SO 4 , which is used for the pink aluminosilicate glass in high viscosity with high temperature state, total content of the clarificant is 0.1-3% of a content of a batch, wherein the SnO content accounts for 10%-80% of the total content of the clarificant;
