1954年金刚石的首次合成给无机合成开辟了一条广阔的途径。特别是在高温高压下合成新型的稀土材料的研究正在迅速地发展。到目前为止已有五个国家九个研究机构从事新的稀土化合物的高压合成。通常高温高压合成是在对顶年轮式或四面顶压机中进行。用定点标压的办法校正压力。一般在二元化合物的合成时,均用金属和有关元素的单质粉末(通过100目筛孔),按比例
The first synthesis of diamond in 1954 opened up a vast avenue for inorganic synthesis. In particular, the synthesis of new rare earth materials under high temperature and pressure is rapidly developing. To date, nine research institutes in five countries have been engaged in the high pressure synthesis of new rare earth compounds. Usually high temperature and pressure synthesis is carried out on the top of the wheel or four-sided press. Pressure calibration with fixed point method. Generally in the synthesis of binary compounds, both with a single elemental metal and related elements powder (through 100 mesh sieve), in proportion
