At present, there is no effective test method for the glass corrosion resistance of different batch platinum materials from different manufacturers in china. In this paper, a method for testing the glass corrosion resistance of platinum has been established. It can not only evaluate the glass corrosion resistance of platinum materials, but also provide technical analysis for the platinum defects in glass. At temperature system of TFTLCD glass substrate manufacturing, the glass corrosion resistance of Pt, PtRh10, PtRh20 materials and Pt and Rh dissolved quantity were tested by using metallographic analysis and mass spectrometry. The results showed that Pt, PtRh10 and PtRh20 materials were oxidized and volatilized at 1600 ℃; both Pt and Rh are heavy metals, and Pt and Rh ions accumulated easily at the bottom of glass melt; the dissolved quantity of Rh was significantly higher than the of Pt, the Pt/Rh quality ratio was between 1∶4 and 1∶5; Pt and Rh dissolved quantity of PtRh20 platinum materials under the condition of 1600 ℃/18 h was 1.2~1.5 times that under the condition of 1500 ℃/18 h, was 6~10 times that under the condition of 1400 ℃/18 h.
