該產(chǎn)品一般不需研磨加工即可使用.反應(yīng)燒結(jié)法適于制造形狀復(fù)雜,尺寸精確的零件,成本也低,但氮化時(shí)間很長(zhǎng).熱壓燒結(jié)法(HPS)是將Si3N4粉末和少量添加劑(如MgO、Al2O3、MgF2、Fe2O3等),在1916MPa以上的壓強(qiáng)和1600℃以上的溫度進(jìn)行熱壓成型燒結(jié).英國(guó)和美國(guó)的一些公司采用的熱壓燒結(jié)Si3N4陶瓷,其強(qiáng)度高達(dá)981MPa以上.燒結(jié)時(shí)添加物和物相組成對(duì)產(chǎn)品性能有很大的影響.由于嚴(yán)格控制晶界相的組成,以及在Si3N4陶瓷燒結(jié)后進(jìn)行適當(dāng)?shù)臒崽幚?所以可以獲得即使溫度高達(dá)1300℃時(shí)強(qiáng)度(可達(dá)490MPa以上)也不會(huì)明顯下降的Si3N4系陶瓷材料,而且抗蠕變性可提高三個(gè)數(shù)量級(jí).若對(duì)Si3N4陶瓷材料進(jìn)行1400―――1500℃高溫預(yù)氧化處理,則在陶瓷材料表面上形成Si2N2O相,它能提高Si3N4陶瓷的耐氧化性和高溫強(qiáng)度.熱壓燒結(jié)法生產(chǎn)的Si3N4陶瓷的機(jī)械性能比反應(yīng)燒結(jié)的Si3N4要優(yōu)異,強(qiáng)度高、密度大.但制造成本高、燒結(jié)設(shè)備復(fù)雜,由于燒結(jié)體收縮大,使產(chǎn)品的尺寸精度受到一定的限制,難以制造復(fù)雜零件,只能制造形狀簡(jiǎn)單的零件制品,工件的機(jī)械加工也較困難常壓燒結(jié)法(PLS)在提高燒結(jié)氮?dú)夥諌毫Ψ矫?利用Si3N4分解溫度升高(通常在N2=1atm氣壓下,從1800℃開(kāi)始分解)的性質(zhì),在1700―――1800℃溫度范圍內(nèi)進(jìn)行常壓燒結(jié)后。奧翔硅碳公司將以質(zhì)量的產(chǎn)品，完善的服務(wù)與尊敬的用戶攜手并進(jìn)！</p><div
