The experimental results indicate that the initial reaction rates of nano - nah are several orders of magnitude higher than those of the commercial one . the large specific surface area and the high surface energy of nano - nah should be the main factors for their extremely high chemical reactivity . with nano nah , many reactions can be carried out efficiently 實(shí)驗(yàn)進(jìn)一步說(shuō)明,納米nah能使某些原來(lái)熱力學(xué)上允許進(jìn)行但動(dòng)力學(xué)上難以進(jìn)行或"不能進(jìn)行"的有關(guān)反應(yīng)得以進(jìn)行;使一些過(guò)去認(rèn)為低收率無(wú)價(jià)值的反應(yīng),大幅度提高反應(yīng)速率和產(chǎn)率,使其成為有實(shí)際意義的反應(yīng)。
Combined core - shell method with scm , pmw - pnn - pt ceramics with core - shell structure , which have excellent dielectric temperature stability , were successfully prepared . the new mechanism of improving temperature stability of dielectric properties was put forward . the main contents are lis ted as bellows : in the systems of pmn - pt , the effects of the chemical reactivities of the starting materials such as soluble mg - salts instead of mgo , pb - salts instead of pbo and ti ( oc4h9 ) 4 instead of tio2 respectively on the formation of perovskite phase were investigated in detail Scm法與cpm法的工藝相比,工藝簡(jiǎn)單,預(yù)燒溫度和燒結(jié)溫度低,反應(yīng)時(shí)間短;陶瓷致密,介電性能比cmo法和cpm法明顯得到改善,而且在沒(méi)有pt存在時(shí),仍可制得純鈣鈦礦結(jié)構(gòu)的pmn基、 pnn基、 pfw基陶瓷。
