材料科学技术(英文)

Single phase crystalline cubic boron nitride (cBN) with high yield was prepared by hydrothermal route at low temperature, using hydrochloric acid (HCl) as the promoter. The promotion effect of HCl on the synthesis of cBN is briefly discussed.

材料科学技术(英文)

The calculation of the model parameters, lambda(11), lambda(12), lambda(21) and lambda(22), was carried out numerically from the phase diagrams for 11 alkali metal-alkali halide or alkali earth metal-halide systems. In addition, artificial neural network trained by known data has been used to predict the values of these model parameters. The predicted results are in good agreement with the calculated ones. The applicability of the subregular solution model to the alkali metal-alkali halide or alkali earth metal-halide systems were tested by comparing the available experimental composition along the boundary of miscibility gap with the calculated ones which were obtained by using genetic algorithm. The good agreement between the calculated and experimental results across the entire liquidus is valid evidence in support of the model.
