鍺價格

鍺 更多供應(yīng)商 7440-56-4 鍺 價格

性狀
為灰白色金屬。熔點937.4℃。沸點2830℃。相對密度d25295.35, 溶于濃硫酸、硝酸、王水中，不溶于水、堿。
所屬類別
無機化工產(chǎn)品: 無機鹽: Cu單質(zhì)
用途與作用
制造半導(dǎo)體器件用。
合成工藝與制法
工業(yè)生產(chǎn)有坩堝直拉法和懸浮區(qū)熔法。
坩堝直拉法 拉晶前先將設(shè)備各部件、合金石英坩堝、高純鍺和籽晶進行清潔處理。將高純鍺經(jīng)配料和摻雜，加入單晶爐的合金石英坩堝中，再經(jīng)抽真空、熔化，在流通的氬氣氣氛下，人工引晶放肩和收尾。晶體的等徑生長過程中，需根據(jù)情況適當(dāng)調(diào)節(jié)功率，使其獲得直徑均勻的產(chǎn)品。經(jīng)檢測、稱量，制得鍺單晶成品。
