果を第１図に示した。The amount of the Sa compound to be added depends on the composition of the phosphate glass to be added, but the effect of high water resistance becomes noticeable at 0.5 to 20 weight in terms of 80203. In addition, higher water resistance can be stably obtained over a long period of time than when F-A1g03 or B2O3 is added. Added amount is 0
．． If the weight is well below 5, the object of the present invention will not be achieved;
If it exceeds 0'' Aftlb, a homogeneous glass will not be obtained, which is unsuitable.
