【摘要】 本文叙述了天然矿物的导电(绝缘)、介电性能与矿物本身的成份、结构、杂质、多相构造、晶格缺陷与畸变,以及环境温度湿度的关系。通过实例说明,根据使用技术要求,针对矿物的特点,选择合适的提纯去杂改性复合等技术加工手段,可以制备出满足市场需求的低成本电功能材料更多还原

【Abstract】 The relation between the electrical conductivity (isolating property), dielectric property of some natural minerals and the minerals composition, texture, impurity constituents, multiple-phase structure, lattice defect and lattice distortion as well as ambient temperature and atmospheric moisture were briefly described in the paper.Numerous examples have been illustrated that the low cost functional electrical materials meeting market demands can be prepared by selecting suitable processing technologies for purifications and surface modification.更多还原
