黑碳化硅的分類碳化硅(SiC)是用石英砂、石油焦(或煤焦)、木屑為原料通過電阻爐高溫冶煉而成。碳化硅在大自然也存在罕見的礦物，莫桑石。碳化硅又稱碳硅石。在當(dāng)代C、N、B等非氧化物高技術(shù)耐火原料中，碳化硅為應(yīng)用**普遍、**經(jīng)濟(jì)的一種。可以稱為金鋼砂或耐火砂。碳化硅是用石英砂、石油焦(或煤焦)、木屑(生產(chǎn)綠色碳化硅時(shí)需要加食鹽)等原料在電阻爐內(nèi)經(jīng)高溫冶煉而成。目前我國工業(yè)生產(chǎn)的碳化硅分為黑色碳化硅和綠色碳化硅兩種，均為六方晶體，比重為～，顯微硬度為2840～3320kg/mm2。包括黑碳化硅和綠碳化硅，其中：綠碳化硅是以石油焦和質(zhì)量硅石為主要原料,添加食鹽作為添加劑，通過電阻爐高溫冶煉而成。其硬度介于剛玉和金剛石之間,機(jī)械強(qiáng)度高于剛玉。常用的碳化硅磨料有兩種不同的晶體，一種是綠碳化硅，含SiC97%以上，主要用于磨硬質(zhì)含金工具。另一種是黑碳化硅，有金屬光澤，含SiC95%以上，強(qiáng)度比綠碳化硅大，但硬度較低，主要用于磨鑄鐵和非金屬材料。分子式為SiC，其硬度介于剛玉和金剛石之間，廣西鋁廠氮化硅保護(hù)管廠，機(jī)械強(qiáng)度高于剛玉，廣西鋁廠氮化硅保護(hù)管廠，可作為磨料和其他某些工業(yè)材料使用。工業(yè)用碳化硅于1891年研制成功，是**早的人造磨料。在隕石和地殼中雖有少量碳化硅存在，廣西鋁廠氮化硅保護(hù)管廠。奧翔硅碳公司可靠的質(zhì)量保證體系和經(jīng)營管理體系，使產(chǎn)品質(zhì)量日趨穩(wěn)定。廣西鋁廠氮化硅保護(hù)管廠</p><div

</p><p> 產(chǎn)品名稱：氮化硅保護(hù)管。特點(diǎn)：具有密度小，重量輕（／cm3），耐磨、抗氧化、自潤滑、耐腐蝕、電絕緣，高揚(yáng)氏模量（300GPa）絕緣，無磁性。產(chǎn)品特性：氮化硅是一種新型高性能的耐火制品，有較好的熱震穩(wěn)定性?；瘜W(xué)性能穩(wěn)定，抗高溫蠕變、抗酸性、抗堿性、抗氧化性能優(yōu)異，抗鋁（Al）、鉛（Pb）、錫（Sn）、鋅（Zn）、銅（Cu）等熔融金屬侵蝕，電絕緣性良好，常溫比電阻高，用于鋁液、鋅液、銅液等有色金屬加熱、保溫、均化、重熔等方面。檢測技術(shù)擁有溫度檢測等檢測設(shè)備，檢測性能。硅碳棒保護(hù)管幾何尺寸的選擇:電爐的爐膛是由被加熱物的尺寸推算而決定，因而硅碳管的尺寸也相應(yīng)確定下來，現(xiàn)舉例說明如下：如被加熱物是70×500mm的石英管（這里的500mm是指石英管的受熱區(qū)，實(shí)際上石英管還要長）則硅碳管的規(guī)格可選用90/80×500/100，二爐膛的高鋁管則可選用其內(nèi)徑為100mm，其長度要略長于500mm。我公司生產(chǎn)的產(chǎn)品、設(shè)備用途非常多。</p><div
