CrO_3,δ-CrO_2,Cr_2O_3,α-Al_2O_3的熔点、沸点和在水及其它溶液中溶解度的电子理论

根据作者发展的“固体与分子经验电子理论”,从CrO_3,δ-CrO_2,Cr_2O_3,α-A1_2O_3的晶体结构和中子衍射测得的原子Cr的磁矩值直接分析了上四种氧化物的价电子键结构。根据这些键结构,在可以查到的实验资料中,发现不仅对熔点而且对沸点和在水及其它溶液中的溶解度也得到合理的定性理解,因而对实际的固体化学在价电子结构的深度上进行了一次试探。

Interpretation of Melting Point and Certain Other Physical and Chemical Properties ofCrO_3,δ-CrO_2,Cr_2O_3,α-A1_2O_3 by Their Valence Electron Structures

On the basis of the empirical electron theory ot solids and molecules the valence electron structures of CrO3, δ-CrO2, Cr2O3, α-Al2O3 are directly determined from the crystal structures of the four oxides together with the atomic magnetic monents of. Cr determined from electron detraction experiments. According to their valence electron structures it is found that not only the melting points, but also the boiling points, decomposition and solubilities in water and other liquid solvents, such as acids, alkaline and others can be qualitatively interpretated very reasonably and naturally. It means that from the crystal structures of the oxides, we have made a trial to understand the chemistry and physics of solids at the depth of their valence electron structure level.
