將硅灰與Al2O3微粉均勻地分敞，可加入分散劑或采用氣流式混合設(shè)備。粘土的加入量很少，而且要求粘土中堿金屬和堿土金屬氧化物的含量極低。通常以糊精做結(jié)合劑。這種方法的優(yōu)點很明顯：①結(jié)合物的含量可隨意調(diào)整，高達30%時能保證將SiC顆粒充分地包裹起來，從而阻止了SiC在使用過程中的氧化現(xiàn)象，減少了SiC窯具的落渣現(xiàn)象。②原料硅灰與Al2O3微粉具有較大的活性，在較低溫度下既能形成莫來石，比如1000?1100℃能開始固相反應(yīng)，1380℃能形成結(jié)晶良好的莫來石。其燒成制度1380℃×6小時左右，遠低于一般的SiC制品。③由于原料非常純凈，粘土含量極少，在上述燒成條件下很少產(chǎn)生液相，即該種莫來石結(jié)合SiC窯具中極少有玻璃相存在，并且阻止了因玻璃化和方石英的形成而導(dǎo)致的脆性，這樣窯具的強度隨使用時間的廷長而下降較少，熱震穩(wěn)定性大為改善，使用壽命大幅度提高。為了保證硅灰具有較高的反應(yīng)活性，同時盡可能減少反應(yīng)燒結(jié)時液相出現(xiàn)的數(shù)量，應(yīng)選用純度較高的硅灰。莫來石結(jié)合SiC窯具用硅灰的一般性能為：、、、、、，顆粒直徑?μm，比表面積18?20m2/g。引入硅灰的莫來石結(jié)合SiC窯具性能如表1所列。山西陶瓷碳化硅窯具廠奧翔硅碳過硬的產(chǎn)品質(zhì)量、質(zhì)量的售后服務(wù)、認真嚴格的企業(yè)管理，贏得客戶的信譽。</p><div

如何提高碳化硅窯具的使用壽命作者：寰洋實業(yè)發(fā)布日期：2017-09-08非氮化物碳化硅窯具的主要損毀機理為氧化，即碳化硅首先氧化成玻璃態(tài)SiO2，繼而析出方石英。隨著氧化繼續(xù)，非氧化物結(jié)合的碳化硅筑建變質(zhì)成為氧化物結(jié)合碳化硅。后，碳化硅窯具受熱震作用破壞或受SiC不斷氧化成SiO2，產(chǎn)生越來越大的體積變化應(yīng)力作用而損壞。提高碳化硅窯具使用壽命的主要途徑在于提高材料的抗氧化性，提高抗氧化的主要途徑在于在碳化硅表面形成一層高純、致密、牢固和低擴散率的SiO2釉層。碳化硅窯具分為氧化物結(jié)合碳化硅、氮化物結(jié)合碳化硅，重結(jié)晶碳化硅和金屬硅結(jié)合碳化窯具等品種。氧化物結(jié)合碳化硅以氧化物為結(jié)合劑，通過燒結(jié)形成碳化硅-氧化物結(jié)合物復(fù)相的顆粒復(fù)合耐火材料。重結(jié)晶碳化硅系高溫真空之下碳化硅形成籽結(jié)合而制造的碳化硅材料。氮化物結(jié)合碳化硅系以氮化物為結(jié)合相，在含氮氣氛之下燒結(jié)形成碳化硅-氮化物結(jié)合物復(fù)相的顆粒復(fù)合耐火材料。金屬硅結(jié)合碳化硅可能是燒成溫度下碳和過量金屬硅經(jīng)反應(yīng)燒結(jié)產(chǎn)生結(jié)合，再浸漬液態(tài)金屬硅制成的高致密材料。氧化物結(jié)合碳化硅細分為粘土結(jié)合碳化硅和氧化硅結(jié)合碳化硅。粘土結(jié)合碳化硅系以粘土作為結(jié)合劑，通過燒結(jié)制成的耐火材料制品。公司實力雄厚，產(chǎn)品質(zhì)量可靠。</p><div
