硅碳棒
硅(gui)碳(tan)棒是用高(gao)(gao)純度六方(fang)碳(tan)化(hua)(hua)硅(gui)為(wei)主要原(yuan)料，按一(yi)定(ding)料比(bi)加工(gong)制(zhi)坯，經2200℃高(gao)(gao)溫(wen)(wen)硅(gui)化(hua)(hua)再結(jie)晶燒結(jie)而制(zhi)成的棒狀、管狀非金(jin)屬高(gao)(gao)溫(wen)(wen)電(dian)熱(re)元件。硅(gui)碳(tan)棒使(shi)用溫(wen)(wen)度高(gao)(gao)，具(ju)有(you)耐高(gao)(gao)溫(wen)(wen)、抗(kang)氧(yang)化(hua)(hua)、耐腐蝕、升溫(wen)(wen)快、壽命長、高(gao)(gao)溫(wen)(wen)變形小、安(an)裝維修方(fang)便等(deng)特(te)點
