【摘要】 本文研究掺杂 BaTiO₃来提高铬酸镧材料的电阻。通过对烧结时间、掺杂 BaTiO₃比例的研究,发现掺杂 BaTiO₃铬酸镧材料的电阻率随烧结时间的增大呈现下降趋势。掺杂质量比1～2%的铬酸镧在烧结20h 后,电阻率基本稳定,使铬酸镧材料电阻可调。更多还原

【Abstract】 Improvement of LaCrO₃ resistance by doped BaTiO₃ was studied in this paper.Through contrasting the sinter time,doped contents of BaTiO₃,it was found that resistance ratio of LaCrO₃ by doped BaTiO₃ descend with the sinter time increase.After sinter 20h,the resistance ratio of LaCrO₃ by doped 1～2% BaTiO₃ keeps steadily that makes the LaCrO₃ resistance adjustably.更多还原
