Abstract
【解決手段】粒界絶縁型半導体セラミックは、主成分がSrTiO3系化合物で形成されると共に、粒界絶縁化剤とガラス成分とを含む拡散剤が含有されている。粒界絶縁化剤は、Pbを含まない非Pb系材料で形成されると共に、ガラス成分が、B及びPbを含まないSiO2−XO2−MO−TiO2系ガラス材(Xはアルカリ金属、MはBa、Sr、Caから選択された少なくとも1種を示す。)を主成分とし、かつ、前記ガラス成分の含有量は、前記粒界絶縁化剤100重量部に対し3〜15重量部である。部品素体2は、この粒界絶縁型半導体セラミックで形成されている。
【選択図】図1
Description
絶縁化素材として、Bi2O3、CuO、Pb3O4を用意した。そして、これら絶縁化素材を表1に示すような成分組成となるように混合して調製し、粒界絶縁化剤A〜Eを作製した。
セラミック素原料として、SrCO3、CaCO3、TiO2、及びY2O3を用意した。そして、これらのセラミック素原料を(Sr0.795Ca0.200Y0.005)TiO3の組成となるように秤量した。次いで、これらをボールミルを使用し、16時間湿式で混合し、蒸発乾燥した後、1150℃の温度で2時間仮焼し、仮焼物を得た。次に、この仮焼物に有機バインダ、可塑剤、分散剤、水を加えて混錬し、スラリーを得た。このスラリーを、所定形状の成形型に投入し、押出し成形機を用いてチューブ状に成形し、乾燥機で乾燥させた後、角筒形状に切断して成形体を得た。得られた成形体を400〜1100℃の温度で4時間焼成し、有機バインダを除去した後、N2:95%、H2:5%の還元性雰囲気下、1400〜1450℃の温度で3時間、焼成処理を行い、角筒形状の焼結体を得た。尚、この焼結体の寸法は、辺長が1.7mm、内径が1.0mm、長さが40mmであった。
