但還是有簡(jiǎn)單普及一下的必要的，氮化硅結(jié)合碳化硅材料是以SiC和Si為主要組分，并加入添加劑制成試樣，在氮化爐中輸入純度為，在合適的燒成制度下試樣氮化燒結(jié)成為氮化硅結(jié)合碳化硅材料。的研究表明經(jīng)過(guò)對(duì)試樣的顯微結(jié)構(gòu)分析和反應(yīng)熱力學(xué)分析，該材料中的Si3N4是以纖維狀和柱狀兩種形態(tài)存在，認(rèn)為Si的氮化是由于N2達(dá)不到的純凈，其中有少量O2存在，裝窯過(guò)程是在日常環(huán)境下進(jìn)行，然后再抽真空并注入N2置換，爐內(nèi)呈微正壓狀態(tài)。由于窯爐難以做到完全的封閉，所以在窯爐升溫過(guò)程中Si首先被氧化成為SiO，降低了體系中的氧分壓，當(dāng)氧分壓足夠低時(shí)，Si與N2直接形成柱狀Si3N4，氣態(tài)SiO亦可與N2反應(yīng)生成Si3N4，這是一個(gè)氣-氣反應(yīng)，故生成的Si3N4為纖維狀。氮化反應(yīng)前SiO主要分布于材料孔隙和表面，因此生成的Si3N4分布不均勻，導(dǎo)致了氮化硅結(jié)合碳化硅材料制品從表面到內(nèi)部的結(jié)構(gòu)不均勻。氮化硅結(jié)合碳化硅材料強(qiáng)度大,抗熱震、導(dǎo)熱性好。因此，可制作大、薄型類棚板，這樣可有效的延長(zhǎng)窯具使用壽命，減少耐火材料與制品的比例，節(jié)約能耗。另外,和同面積的其他材料窯具相比，其單位價(jià)格也占有優(yōu)勢(shì)。比如咸陽(yáng)陶瓷研究設(shè)計(jì)院生產(chǎn)的520mm×500mm的氮化硅結(jié)合碳化硅棚板厚度10-12mm。吉林耐腐蝕碳化硅結(jié)合氮化硅批發(fā)奧翔硅碳生產(chǎn)的產(chǎn)品受到用戶的一致稱贊。</p><div

這樣的一種循環(huán)工藝操作以表象上的準(zhǔn)靜態(tài)、實(shí)質(zhì)上連續(xù)的動(dòng)態(tài)平衡可使氮化反應(yīng)高速進(jìn)行。我們說(shuō)了幾點(diǎn)有關(guān)氮化硅結(jié)合碳化硅制品氮化燒結(jié)的主要影響因素，簡(jiǎn)單說(shuō)一下氮化硅結(jié)合碳化硅在氮化燒結(jié)過(guò)程是氮化硅及其復(fù)合材料生產(chǎn)的技術(shù)關(guān)鍵，經(jīng)過(guò)對(duì)氮化硅生成機(jī)理的研究，我們確定了產(chǎn)品燒成制度中的氮壓控制燒成工藝方法。從上述的機(jī)理表述中我們知道氮化硅生成過(guò)程是一個(gè)放熱反應(yīng)過(guò)程，如果單純從窯爐的外顯溫度控制，就可能在某一溫度點(diǎn)使硅融化而堵塞向制品深層氮化的通道，加大了由表及里的氮化率梯度，所以我們通過(guò)對(duì)窯爐內(nèi)氮?dú)夥謮旱目刂?，?lái)實(shí)現(xiàn)對(duì)反應(yīng)速度的控制，可以得到制品從外到里氮化率梯度趨近于零的結(jié)果。氮化硅結(jié)合碳化硅制品氮化燒結(jié)的主要影響因素是氮化反應(yīng)的時(shí)間，而兩級(jí)保溫之間的溫度大小和氮化燒結(jié)**終溫度的高低使這兩個(gè)因子對(duì)試樣增重率的影響相對(duì)較大。經(jīng)過(guò)我們?cè)囼?yàn)分析對(duì)在氮化硅結(jié)合碳化硅材料的氮化燒結(jié)過(guò)程中有以下幾點(diǎn)：1.適當(dāng)提高反應(yīng)起始溫度，加速初始氮化反應(yīng)，不會(huì)造成“流硅”現(xiàn)象。2.在反應(yīng)中溫區(qū)，可適當(dāng)加大兩級(jí)保溫之間的溫差，加速中溫區(qū)的反應(yīng)速率。3.比較高燒成溫度可在較大的范圍內(nèi)波動(dòng)，不像液相燒結(jié)陶瓷制品時(shí)那么嚴(yán)格。</p><p>
