The refractive indices in the PbOㆍ B_(2)O_(3)ㆍA1_(2)O_(3) glass system have been measured by the Liquid Immerson method under the Leitz-Orthohxpd Pola-rizing microscope as function of the PbO composition.
The refractive idex is increasing in proportion to the PbO camposition without any connection with A1_(2)O_(3), ccmposition. However, it does not increase above 45 mol, % PbO composition.
The reason is that amount of Pb ion acts as the glass modifier under the 45mol, %PbO in the PbOㆍB_(2)O_(3)ㆍA1_(2)O_(3) glass system, and that parts of Pb ion become the formation a tom of glass acts as the glass former with the above 45 mol, % PbOㆍB_(2)O_(3)ㆍA1_(2)O_(3) glass system.
