氮化硅的強(qiáng)度很高，尤其是熱壓氮化硅，是世界上**堅(jiān)硬的物質(zhì)之一。它極耐高溫，強(qiáng)度一直可以維持到1200℃的高溫而不下降，受熱后不會熔成融體，一直到1900℃才會分解，并有驚人的耐化學(xué)腐蝕性能，能耐幾乎所有的無機(jī)酸和30%以下的燒堿溶液，也能耐很多有機(jī)酸的腐蝕；同時(shí)又是一種高性能電絕緣材料。氮化硅-性質(zhì)化學(xué)式Si3N4。白色粉狀晶體;熔點(diǎn)1900℃,密度3.44克/厘米(20℃)；有兩種變體：α型為六方密堆積結(jié)構(gòu)；β型為似晶石結(jié)構(gòu)。氮化硅有雜質(zhì)或過量硅時(shí)呈灰色。主要應(yīng)用于高溫行業(yè)。其中碳化硅保護(hù)管占了主要的位置。

但迄今尚未找到可供開采的礦源。純碳化硅是無色透明的晶體。工業(yè)碳化硅因所含雜質(zhì)的種類和含量不同，而呈淺黃、綠、藍(lán)乃至黑色，透明度隨其純度不同而異。碳化硅晶體結(jié)構(gòu)分為六方或菱面體的α-SiC和立方體的β-SiC(稱立方碳化硅)。α-SiC由于其晶體結(jié)構(gòu)中碳和硅原子的堆垛序列不同而構(gòu)成許多不同變體，已發(fā)現(xiàn)70余種。β-SiC于2100℃以上時(shí)轉(zhuǎn)變?yōu)棣?SiC。碳化硅的工業(yè)制法是用質(zhì)量石英砂和石油焦在電阻爐內(nèi)煉制。煉得的碳化硅塊，經(jīng)破碎、酸堿洗、磁選和篩分或水選而制成各種粒度的產(chǎn)品。碳化硅有黑碳化硅和綠碳化硅兩個(gè)常用的基本品種，都屬α-SiC。①黑碳化硅含SiC約，其韌性高于綠碳化硅，大多用于加工抗張強(qiáng)度低的材料，如玻璃、陶瓷、石材、耐火材料、鑄鐵和有色金屬等。②綠碳化硅含SiC99%以上，大多用于加工硬質(zhì)合金、鈦合金和光學(xué)玻璃，也用于珩磨汽缸套和精磨高速鋼。此外還有立方碳化硅，它是以特殊工藝制取的黃綠色晶體，用以制作的磨具適于軸承的超精加工，可使表面粗糙度從Ra32～～。碳化硅是一種磨料.砂輪是用磨來料和結(jié)合劑樹脂等制成的**有通孔的圓形固結(jié)磨具.砂輪是磨具中用量比較大、使用面**廣的一種,使用時(shí)高速旋轉(zhuǎn)。奧翔硅碳有著質(zhì)量的服務(wù)質(zhì)量和極高的信用等級。江蘇鋁行業(yè)氮化硅保護(hù)管價(jià)格</p><p
