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,而市場(chǎng)上同面積的高鋁質(zhì)和硅酸鹽結(jié)合SiC棚板等厚度一般都在20-400mm左右，二者比校,氮化硅結(jié)合碳化硅棚板單位重址成倍的減少,單位價(jià)格相比較也便宜。因此，該材料的薄型棚板類，在市場(chǎng)上有很強(qiáng)的競(jìng)爭(zhēng)力。氮化硅結(jié)合碳化硅以其良好的材性可制作輕量化、組合化的支柱中空橫輛類的窯具，此種窯具結(jié)構(gòu)簡(jiǎn)單外觀尺寸小、承受彎曲應(yīng)力大，使用壽命長(zhǎng)從而使產(chǎn)品裝載系數(shù)加大，也大量節(jié)約了能耗是現(xiàn)代窯具的必然發(fā)展趨勢(shì)。氮化硅結(jié)合碳化硅在制作窯具成型工藝上一般有：半干成型、注漿成型和等靜壓成型三種，氮化燒成是制備氮化硅結(jié)合碳化硅材料的關(guān)鍵步驥，其結(jié)果是一定要氮化完全，使制品中的殘留游離硅降至比較低。這里主要是控制反應(yīng)速度，若反應(yīng)過(guò)于激烈、原料中的Si被放出的熱熔融而結(jié)塊，造成反應(yīng)不完全，破壞制品的結(jié)構(gòu)。另外在實(shí)際生產(chǎn)中產(chǎn)品規(guī)格多樣，厚薄各異，要預(yù)先確定每種產(chǎn)品所需的氮化時(shí)間及速度困難較大，氮化難以完全。因此。</p><p
