ANTIMONY CONTAINING CONDUCTIVE MAGNESIUM INDATE AND PRODUCTION THEREOF

PURPOSE:To provide an inorganic conductive material and the production method having small in coloring, having light transmissivity, low in volume specific resistance and prevented in the deterioration of volume specific resistance with the elapse of time. CONSTITUTION:In the antimony containing conductive indate magnesium, the composition is expressed by MgxInySbzO4 in which z/(x+y+z) is 0.005-0.01 and (x+y+z)/x is 2.5-2.99. And the production method for antimony containing conductive magnesium indate is comprises a step produce a fired product by firing the mixture of the indiumacid magnesium indate or the precursor with an antimony compound at high temp., which has a composition expressed by MgxInySbzO4 and is 0.0005-0.01 in z/(x+y+z), 2.5-2.99 in (x+y+z)/x, and a step to burn the fired product in a nonoxidizing atmosphere at 600-800 deg.C.
