矿物的导电类型与矿物形成温度的关系

RELATION BETWEEN THE ELECTRIC CONDUCTIVE TYPES OF MINERALS AND THE MINERALIZATION TEMPERATURES

通过杂质对导电类型的影响的研究,得出了同种矿物的不同导电类型与矿物形成温度的规律:电子型(n型)导电矿物的形成温度大于电子与空穴混合型导电矿物的形成温度,又大于空穴型(p型)导电矿物的形成温度,绝缘体矿物的形成温度低于上述三种导电类型矿物。应用矿物热电图谱仪,天然金刚石半导体测试仪对闪锌矿、黄铁矿、金刚石等矿物的导电类型进行了测试,并探讨了导电类型成因,证实了上述规律的正确性。

The paper explored the influence of impurities to the electric conductive types, it obtained that the relation between the different electric conductive types of the same minerals and the mineralization temperatures is followed:the mineralization temperature of electronic (n-type) electric conductive minerals>the mineralization temperature of the hole-electronic mixed electric conductive minerals>the mineralization temperature of the holeelectric (p-type) conductive minerals>the mineralization temperature of the insulative minerals. By using the self-designed pyroelectricity graphic instrument and the natural semiconductive diamcnd detector, the electric conductive types of the minerals, such as sphalerite, pyrite and diamond have been tested, at the same time, the cause of formation of the electric conductive types are also explored. Both of them confirm that the above law is correct.
