氮化硅制品想必大家都不陌生，它的粉末對(duì)于燒結(jié)制品起到非常重要的作用，但是在高溫條件下卻不能被氫氣還原的，除此之外它還不導(dǎo)電，屬于一個(gè)絕緣體，下面就給具體的大家介紹一下這幾個(gè)問(wèn)題：一、粉末對(duì)燒結(jié)制品性能的影響1、影響粉末冶金燒結(jié)體性能的因素很多，主要是粉末體的性狀、成形條件和燒結(jié)的條件。2、燒結(jié)條件的因素包括加熱速度、燒結(jié)溫度和時(shí)間、冷卻速度、燒結(jié)氣氛及燒結(jié)加壓狀況等。二、不導(dǎo)電：那是因?yàn)樗慕Y(jié)構(gòu)與金剛石相似，也是原子晶體，硬度超過(guò)金剛石。電子沒(méi)有傳遞的通道，所以不能導(dǎo)電。三、高溫下不被還原：1、高溫下是不能被氫氣還原的，因?yàn)楫a(chǎn)品性能比較穩(wěn)定，是一種重要的結(jié)構(gòu)陶瓷材料。它是一種超硬物質(zhì)，為原子晶體高溫時(shí)抗氧化。2、它還能抵抗冷熱沖擊，在空氣中加熱到1000℃以上，急劇冷卻再急劇加熱，也不會(huì)碎裂。人們常常利用它來(lái)制造軸承、氣輪機(jī)葉片、機(jī)械密封環(huán)、長(zhǎng)久性模具等機(jī)械構(gòu)件。氮化硅制品憑借良好的性質(zhì)被大家普遍的接受，具有耐磨損、耐腐蝕、潤(rùn)滑性強(qiáng)等多個(gè)特點(diǎn)，而且它不單單可以應(yīng)用在陶瓷行業(yè)，還能提高柴油機(jī)的質(zhì)量、熱效率，是一個(gè)多功能物質(zhì)。吉林鑄造氮化硅保護(hù)管廠(chǎng)奧翔硅碳技術(shù)力量雄厚，工裝設(shè)備和檢測(cè)儀器齊備，檢驗(yàn)與實(shí)驗(yàn)手段完善。</p><div

黑碳化硅的分類(lèi)碳化硅(SiC)是用石英砂、石油焦(或煤焦)、木屑為原料通過(guò)電阻爐高溫冶煉而成。碳化硅在大自然也存在罕見(jiàn)的礦物，莫桑石。碳化硅又稱(chēng)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(chēng)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(guó)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(guò)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，機(jī)械強(qiáng)度高于剛玉，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。

氮化硅制品、氮化硅陶瓷的制備技術(shù)在過(guò)去幾年發(fā)展很快,制備工藝主要集中在反應(yīng)燒結(jié)法、熱壓燒結(jié)法和常壓燒結(jié)法、氣壓燒結(jié)法等類(lèi)型.由于制備工藝不同,各類(lèi)型氮化硅陶瓷具有不同的微觀(guān)結(jié)構(gòu)(如孔隙度和孔隙形貌、晶粒形貌、晶間形貌以及晶間第二相含量等).因而各項(xiàng)性能差別很大[9].要得到性能優(yōu)良的Si3N4陶瓷材料,首先應(yīng)制備高質(zhì)量的Si3N4粉末.用不同方法制備的Si3N4粉質(zhì)量不完全相同,這就導(dǎo)致了其在用途上的差異,許多陶瓷材料應(yīng)用的失敗,往往歸咎于開(kāi)發(fā)者不了解各種陶瓷粉末之間的差別,對(duì)其性質(zhì)認(rèn)識(shí)不足.一般來(lái)說(shuō),高質(zhì)量的Si3N4粉應(yīng)具有α相含量高,成均勻,雜質(zhì)少且在陶瓷中分布均勻,粒徑小且粒度分布窄及分散性好等特性.好的Si3N4粉中α相至少應(yīng)占90%,這是由于Si3N4在燒結(jié)過(guò)程中,部分α相會(huì)轉(zhuǎn)變成β相,而沒(méi)有足夠的α相含量,就會(huì)降低陶瓷材料的強(qiáng)度.反應(yīng)燒結(jié)法(RS)是采用一般成型法,先將硅粉壓制成所需形狀的生坯,放入氮化爐經(jīng)預(yù)氮化(部分氮化)燒結(jié)處理,預(yù)氮化后的生坯已具有一定的強(qiáng)度,可以進(jìn)行各種機(jī)械加工(如車(chē)、刨、銑、鉆).,在硅熔點(diǎn)的溫度以上;將生坯再一次進(jìn)行完全氮化燒結(jié),得到尺寸變化很小的產(chǎn)品(即生坯燒結(jié)后,收縮率很小,線(xiàn)收縮率<。奧翔硅碳始終以適應(yīng)和促進(jìn)工業(yè)發(fā)展為宗旨。</p><div

氮化硅粉：隨著現(xiàn)代科學(xué)技術(shù)的發(fā)展,對(duì)新材料的研究和應(yīng)用不斷提出更高的要求,傳統(tǒng)的金屬材料越來(lái)越難以滿(mǎn)足這種日益發(fā)展的要求,及待開(kāi)發(fā)新型材料.多年來(lái),研究工作者們進(jìn)行了不懈的努力,在材料的制備工藝和性能方面取得了很大的進(jìn)展.氮化硅陶瓷的基本性質(zhì)Si3N4陶瓷是一種共價(jià)鍵化合物,基本結(jié)構(gòu)單元為[SiN4]四面體,硅原子位于四面體的中心,在其有四個(gè)氮原子,分別位于四面體的四個(gè)頂點(diǎn),然后以每三個(gè)四面體共用一個(gè)原子的形式,在三維空間形成連續(xù)而又堅(jiān)固的網(wǎng)絡(luò)結(jié)構(gòu).氮化硅的很多性能都?xì)w結(jié)于此結(jié)構(gòu).純Si3N4比重為3119,有α和β兩種晶體結(jié)構(gòu),均為六角晶形,其分解溫度在空氣中為1800℃,在011MPa氮?dú)庵袨?850℃.Si3N4熱膨脹系數(shù)低、導(dǎo)熱率高,故其耐熱沖擊性較好.熱壓燒結(jié)的氮化硅加熱到l000℃后投入冷水中也不會(huì)破裂.在不太高的溫度下,Si3N4具有較高的強(qiáng)度和抗沖擊性,但在1200℃以上會(huì)隨使用時(shí)間的增長(zhǎng)而出現(xiàn)破損,使其強(qiáng)度降低,在1450℃以上更易出現(xiàn)疲勞損壞,所以Si3N4的使用溫度一般不超過(guò)1300℃.由于Si3N4的理論密度低,比鋼和工程超耐熱合金鋼輕得多,所以。奧翔硅碳公司可靠的質(zhì)量保證體系和經(jīng)營(yíng)管理體系，使產(chǎn)品質(zhì)量日趨穩(wěn)定。河南耐高溫氮化硅保護(hù)管零售</p><p
