水热法合成BaTiO_3微粉及其半导化掺杂的研究

Homogeneous Dopants of BaTiO_3 Ultrafine Powders by Hydrothermal Method

本文讨论在水热法合成高纯超细钛酸钡微粉过程中，进行半导化掺杂钇、铌、镧、锑等的研究，结果表明：在以ＹＣｌ３和Ｌａ（ＣＨ３ＣＯ２）２为原料时，可获得掺杂的钛酸钡粉末，经烧结后可获得良好的ＰＩＣ效应。

Semiconductor dopants (Y, La) of BaTiO3 ultrafine powders under hydrothermal conditions are described. Homogeneous dopants of BaTiO3 powders from soluble YCl3 or La (CH3CO2)3 were obtained, after properly calcine the ceramic presented good PTCR effects.
