This refers to a compound that does not follow the law of definite proportions. Also known as a bertholide compound or a nonstoichiometric compound. This refers to interstitial compounds and lattice defect compounds, such as oxides, sulfides, hydrides, carbides, and borides of transition metals, whose atomic ratios do not follow simple integer ratios. For example, PdH(/x) (x = 0-0.71), TiO(/x) (x = 1.90-2.00). Many of these compounds are important as semiconductors, ferroelectrics, solid catalysts, and magnetic materials. The oxides of high-temperature superconductors are also compounds of this type. Source : Heibonsha Encyclopedia About MyPedia Information |
定比例の法則に従わない化合物をいう。ベルトライド化合物,不定比化合物などとも。侵入型化合物や格子欠損化合物,たとえば遷移金属の酸化物,硫化物,水素化物,炭化物,ホウ化物などで,その原子比が一定の簡単な整数比にならないようなものをいう。PdH(/x)(x=0〜0.71),TiO(/x)(x=1.90〜2.00)など。半導体,強誘電体,固体触媒,磁性材料などとして重要なものが多い。高温超伝導体の酸化物も,このタイプの化合物である。
