氧化鋁陶瓷從結(jié)構(gòu)陶瓷的角度看,氧化鋁陶瓷可分為耐磨部件、結(jié)構(gòu)部件、耐火部件、載體、耐酸部件、絕緣部件等等。從功能方面看,氧化鋁陶瓷具有電學(xué)、光學(xué)、化學(xué)、生物、吸聲、熱學(xué)、力學(xué)等多種功能。
以納米氧化鋁(VK-L05C)為主要原料制得的納米氧化鋁精細陶瓷,因具有多種功能,在高科技術(shù)領(lǐng)域及許多行業(yè)中已得到應(yīng)用。多芯片式封裝用陶瓷多層基板:封裝用的納米氧化鋁陶瓷多層基板的制造方法有厚膜印刷法、生坯疊片法、生坯印刷法、厚薄膜混合法等四種。
用納米氧化鋁陶瓷的晶粒、晶界、氣孔等結(jié)構(gòu)特征和特性作敏感元件,用于高溫和含腐蝕性氣體的環(huán)境中,使檢測、控制的信息準確而迅速。從應(yīng)用的類型看,有溫度、氣體、溫度等傳感器。
納米氧化鋁的硬度(Hr)為2700~3000,楊氏模量(kg/mm2)35000~41000。導(dǎo)熱系數(shù)0.75~1.35×103J/m·h·℃,熱膨脹系數(shù)8.5×10-6/℃(室溫~1000℃)。人們在利用這些特性的同時,又開發(fā)了Al2O3~TiO2,Al2O3-ZrO2系陶瓷,以改善納米氧化鋁陶瓷刀具的韌性和耐熱沖擊性,適應(yīng)高速切削的需要。(圖/文www.tuizz.cn)
