1、氮化硅結(jié)合碳化硅制品，質(zhì)地堅(jiān)硬，莫氏硬度約為9，在非金屬材料中屬于硬度材料，僅次于金剛石。 2、氮化硅結(jié)合碳化硅制品的常溫強(qiáng)度高，在1200-1400℃高溫下，幾乎保持與常溫相同時(shí)間的強(qiáng)度和硬度。隨著使用氣氛的不同，比較高安全使用溫度可達(dá)到1650-1750℃。 3、熱膨脹系數(shù)小，相比碳化硅等制品熱導(dǎo)率高，不易產(chǎn)生熱應(yīng)力，具有良好熱震穩(wěn)定性，使用壽命長。高溫抗蠕能力強(qiáng)，耐腐蝕，耐極冷極熱、抗氧化，易制成尺寸精度高符合要求的制品。 4、產(chǎn)品廣泛應(yīng)用于鋼鐵、有色金屬、化工建材等多種行業(yè)，節(jié)能、環(huán)保、降低成本。</p><p> 其中碳化硅微粉的表面處理占有很重要的地位。氮化硅結(jié)合碳化硅制品生產(chǎn)工藝中，需要加入臨時(shí)的結(jié)合劑，結(jié)合劑的加入主要有兩大功效，一是可以幫助原料之間融合實(shí)現(xiàn)均質(zhì)體，改善原料顆粒表面的分散性，為胚體成型創(chuàng)建良好的條件；二是氮化硅結(jié)合碳化硅制品在干燥和燒成的工序中要面臨升溫的過程，而在高溫條件下，氮化硅結(jié)合碳化硅制品中的臨時(shí)結(jié)合劑會(huì)分解，氣態(tài)物質(zhì)揮發(fā)過程中給氮化硅結(jié)合碳化硅制品留下大量的網(wǎng)絡(luò)狀氣孔通道，不僅更有利于氮?dú)獾某淙耄岣吡斯璺酆偷獨(dú)庵g的反應(yīng)效率，而且也能夠更有利于**終產(chǎn)品的穩(wěn)定性。臨時(shí)結(jié)合劑主要有：有機(jī)糊精、木質(zhì)素磺酸鈣以及德國司馬化工分散劑等等，目前行業(yè)內(nèi)對于臨時(shí)結(jié)合劑的添加量質(zhì)量百分比通常在5%以內(nèi)。氮化硅結(jié)合碳化硅制品涉及到的主要生產(chǎn)原料有：碳化硅、硅粉、氮?dú)獾忍砑觿２煌谄胀ǖ牡璨牧现破?，氮化硅結(jié)合碳化硅制品所需要的原料必須具有更高的純度。碳化硅的純度應(yīng)達(dá)到，硅粉的純度應(yīng)達(dá)到99%以上，氮?dú)獾募兌葢?yīng)達(dá)到。除了原料的純度需要進(jìn)行嚴(yán)格的控制之外，生產(chǎn)加工過程中還需要對原料的粒度和顆粒級配進(jìn)行嚴(yán)格的控制。原料的粒度過高將會(huì)直接影響胚體成型的體積密度，造成胚體的致密性降低。奧翔硅碳生產(chǎn)的產(chǎn)品質(zhì)量上乘。</p><div
