| 摘 要： | 研究了表面掺杂和高温烧结对ＴiO2材料的半导化的影响，结果表明：ＴiO2材料在高温条件下可产生间隙离子和氧空位；掺入与Ｔi^4 离子半径相近的Ｖ^5 ,Nb^5 ,Mg^2 ,Li^ 等离子可与ＴiO2生成固熔体，从而增加材料的导电粒子数目，改变了ＴiO2材料的能带结构，降低材料的固有阻值，使ＴiO2材料的半导化。

| Abstract: | The effect of the surface mix and the high-temperature sintering on the semi -conductivity mechanism of TiO2 materials has been studied. The result demons trated that the high-temperature sintering has produced interval ion and oxygen space; that the surface mix with V5 , Nb5 , Sb5 , Mg2 , Li ion has formed solid meltable bodys with the semi-conductivity o f TiO2 materials. These have raised electrical conductivrty, improved the energy belt structure ane reduced the resistance of TiO2 materials. |
