硅碳棒廠家介紹，硅碳棒坯是次燒結(jié)，然后嵌入二氧化硅和碳的混合粉末中。采用電加熱法在2000年高溫下對(duì)碳化硅進(jìn)行再結(jié)晶，得到硅碳棒電熱元件，稱為二次燒結(jié)，也稱為硅化。二氧化硅和碳的混合粉末主要在高溫下在硅碳棒坯周圍形成還原氣氛，硅碳棒坯的氧化，促進(jìn)硅碳棒中碳化硅晶體的生長(zhǎng)。在第二次燒結(jié)過程中，SiC晶體的晶粒尺寸越大，SiC棒的電阻率和表面系數(shù)越小，從而使SiC棒不被氧化，從而提高了SiC棒的壽命。然而，使用二氧化硅和碳會(huì)導(dǎo)致硅碳棒坯中碳化硅顆粒不均勻生長(zhǎng)，造成硅碳棒表面粗糙，影響硅碳棒的質(zhì)量。1、幾何尺寸的選擇電爐的爐膛是由被加熱物的尺寸推算而決定，因而硅碳管的尺寸也相應(yīng)確定下來，現(xiàn)舉例說明如下：如被加熱物是?70×500mm的石英管（這里的500mm是指石英管的受熱區(qū)，實(shí)際上石英管還要長(zhǎng)）則硅碳管的規(guī)格可選用?90/80×500/100，二爐膛的高鋁管則可選用其內(nèi)徑為100mm，其長(zhǎng)度要略長(zhǎng)于500mm。2、硅碳棒保護(hù)管使用的功率硅碳管使用的功率決定于爐子的保溫條件，幾何尺寸及到達(dá)的溫度。對(duì)于較好的保溫條件，恒溫后，硅碳管發(fā)熱區(qū)內(nèi)表面的溫度與被加熱物的溫度相差≦50℃。我們可以利用下式先計(jì)算硅碳管發(fā)熱部單位表面積的負(fù)荷。四川測(cè)硫儀硅碳管奧翔硅碳生產(chǎn)的產(chǎn)品質(zhì)量上乘。</p><div
