摘要： To provide a sputtering target structure which has good machinability and thermal conductivity and has good wettability with soldering materials, which is inexpensive and can be used repeatedly for a long period of time, and which is free from problems of cracking and peeling of the sputtering target therein, a sputtering target structure is formed by bonding a sputtering target and a backing plate. The backing plate is formed of a material that has the difference in the linear expansion coefficient between it and the sputtering target material of at most 2×10−6/K, and a copper plate having a thickness of from 0.3 to 1.5 mm is disposed on at lest one face of the backing plate.

摘要： The present invention relates to giant grains or single crystals of chromium. Hitherto, since single crystals of chromium were generally obtained by a floating zone method, it was difficult to obtain an optionally shaped chromium single crystal. The present invention has been made in order to overcome these problems and provides a process for producing single crystals of chromium by secondary recrystallization. That is, it has been found that control of the amount of impurities present in a chromium component such as, for example, Co, Ti, Al, Si, and Ca, has a good influence on the formation of single crystals of chromium. For example, if chromium to which the above-described Ti, Al, Si, and Ca have been added in an amount of from 0.0002 wt % to 0.1 wt %, calculated as oxides thereof, or to which from 0.01 to 3 wt % of Co has further been added, is sintered and the resulting chromium molding is heated treated, single crystals of chromium having a complicated shape can be obtained.
