And a relative preparation is characterized in that according to mol ratio (0.8-0.975):(1.8-1.95):(0.010-0.15):(0.010-0.15) to prepare and mix Mg powder, B powder, C nanometer powder, and SiC nanometer powder uniformly to be filled into an iron tube or iron-copper composite tube to be sealed, rotationally forges, draws and rolls to obtain MgB2 superconductive material containing C and SiC nanometer powder, or tablets the raw powder mixed uniformly via a tablet press, to obtain MgB2 superconductive block containing C and SiC nanometer powder, arranges obtained band or block in a vacuum furnace, vacuums and fills argon gas, keeps temperature for 0.2-3h at 600-1200DEG C, and obtains MgB2 superconductive material containing C nanometer powder and SiC nanometer powder.

制备这种MgB 2 超导材料的方法，其特征在于，将Mg粉，B粉，C纳米粉，SiC纳米粉按照摩尔比(0.8-0.975)∶(1.8-1.95)∶(0.010-0.15)∶(0.010-0.15)配制并混合均匀，装入铁管或铁铜复合管中密封后，按顺序先后进行旋锻、拉拔、轧制，得到含C和SiC纳米粉的MgB 2 超导线材；或者将混合均匀的原料粉用压片机进行压片，得到含C和SiC纳米粉的MgB 2 超导块材；将得到的线带材或块材放置真空炉中，抽真空后充入氩气，在600℃-1200℃保温0.2-3小时，最终得到含有C纳米粉和SiC纳米粉的MgB 2 超导材料。

A Cu2Se powder and an In2Se3 powder prepared or purchased in the market are mixed in a planetary ball mill for ball milling and then cold-press molding so as to make a biscuit with mixed material of Cu2Se and In2Se3, the biscuit is positioned in a closed vacuum sintering furnace, and is sintered and cooled for de-molding in the H2 protective atmosphere, thereby obtaining the copper indium selenide target.

通过制备或市场购买Cu 2 Se粉末和In 2 Se 3 粉末，混合后在行星式球磨机中球磨，而后冷压成型，制得Cu 2 Se和In 2 Se 3 混合材料素坯，将此素坯置于密闭的真空烧结炉中，在H 2 保护气氛中，烧结，冷却后脱模，即得到铜铟硒靶材。
