日本科学技术厅宣布,日本科学家已研制出在1800℃的高温下仍能耐热的新材料。用粉末陶瓷和金属制成的这种材料与美国航天飞机表面使用的材料相比,前者的耐热性比后者高300℃。用陶瓷、镍、钛和铜的粉末制成的园盘已在试验中投入使用,每个园盘的厚度为2～4毫米,直径3厘米。 Japan Science and Technology Agency announced that Japanese scientists have developed a new material can still heat at 1800 ℃ under high temperature. This material, made of powdered ceramics and metal, has a heat resistance 300 ° C higher than the latter, compared to the material used on the surface of the U.S. space shuttle. Discs made of ceramic, nickel, titanium and copper powders have been put into operation in the test. Each disc has a thickness of 2 to 4 mm and a diameter of 3 cm.
