据估計地球中心的压力为3,000,000大气压,在实驗室中已得到400,000大气压的超高压。很容易想象,在这样大的压力下物貭会有一个新的面貌。利用这种超高压来創制新材料是一个非常迷人的研究領域。大家所熟知的人造金刚石的創制成功已把这个領域的大門打开了。目前用超高压(通常还要結合用高温)已制成的材料有五种,这些材料一般都具有很好的性能。这五种材料是:
It is estimated that the pressure at the center of the Earth is 3,000,000 atmospheres and 400,000 atmospheres of ultrahigh pressure have been obtained in the laboratory. It is easy to imagine that under such a heavy pressure, things will have a new appearance. Using this kind of UHP to create new materials is a fascinating area of research. The well-known success of man-made diamonds has opened the door to this area. At present, there are five kinds of materials that have been made by using ultra-high pressure (usually combined with high temperature), and these materials generally have good performance. These five materials are:
