Title: Manufacture of ceramic superconducting wire rod
Inventor: MATSUMOTO KANAME
IPC: B28B1/00
Filed: 1987-06-15
Abstract: PURPOSE:To make such a ceramic superconductor that is excellent in critical current density Jc or the like securable by applying sintering treatment to the metal pipe filled up with material powder as much as desired frequency in the point midway in a diametral contraction process. CONSTITUTION:Sintering treatment is applied to the metal pipe filled up with material powder as much as desired frequency in the point midway in a diametral contraction process. Thus, the sintering treatment is performed in the midway of the diametral contraction process, whereby a solid phase reaction among powder particles proceeds and simultaneously the metal pipe comes to softness so that compressive force strongly works on the inside powder at the next diametral contraction process, therefore a contact area between powder themselves is increased to some extent, and there is produced of some contact among newly unreacted particles themselves, thus the solid reaction is accelerated at the next sintering treatment. When the diametral contraction process is performed within the temperature range of + or -100 deg.C at sintering temperature, the said action preceeds at the same time during the diametral contraction process. Frequency of the sintering treatment performed in the midway of the diametral contraction process can be done as optional as more than one time, thus the more in frequency, the more improvement in the characteristic value of critical current density Jc or the like. With this constitution, such a ceramic superconducting wire rod that is excellent in this critical current density Jc is securable.
