摘要:

目前國內對于不同廠家不同批次鉑金材質的抗玻璃侵蝕性能沒有有效的測試方法。建立了一種鉑金抗玻璃侵蝕性能檢測方法，既能評估鉑金材料抗玻璃侵蝕性能，也為評估、解決玻璃中鉑金缺陷問題提供數據。通過金相分析、質譜儀分析測試Pt、PtRh10、PtRh20鉑金材料抗玻璃侵蝕性和玻璃中Pt,Rh的溶解量。結果表明：Pt、PtRh10、PtRh20材料在1600 ℃高溫下均有氧化揮發； Pt,Rh均屬于重金屬，Pt,Rh離子易在玻璃液底部積聚；TFT玻璃中Rh溶解量明顯高于Pt，玻璃中Pt，Rh含量比值在1∶4至1∶5之間；在1600 ℃/18 h條件下PtRh20鉑金材料Pt，Rh在玻璃中溶解量是1500 ℃/18 h條件下Pt，Rh在玻璃中溶解量的1.2~1.5倍，是1400 ℃/18 h條件下Pt，Rh在玻璃中溶解量的6~10倍。

Abstract:

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 TFT�睱CD 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.
