据科学研究 ,由于条件的局限性 ,若要冶炼出超高纯度的高熔点金属 ,则非要置于宇宙太空间去熔炼不可。然而现在日本已在人类赖以生存的地球上率先炼出了超高纯的稀金属 ,填补了一项高新技术的空白。前不久 ,日本金属材料技术研究所、中部电子公司和富士电机公司的专家 ,联合研 According to scientific research, due to the limitations of the conditions, to smelt the ultra-high purity of the high-melting point metal, it must be placed in the cosmic space to smelt. Now, however, Japan has taken the lead in refining the ultra-high-purity rare earths on the planet on which mankind depends for survival, filling a gap in high technology. Not long ago, the Japan Institute of Metal Materials Technology, Chubu Electronics and Fuji Electric Company’s experts, joint research
