Title: Preventive method for deterioration of oxide superconductive molding
Inventor: IMAI KUMIKO
IPC: C01G1/00
Filed: 1988-04-30
Abstract: PURPOSE:To prevent deterioration in superconductive characteristics due to crack generator by furnishing an oxide type superconductive molding with voids penetrating from the surface to the rear surface at a certain spacing. CONSTITUTION:Holes 2 penetrating from the surface to the rear surface are provided in an oxide type superconductive molding 1 at a certain spacing. This spacing depends upon the shape of the molding 1 or the size of superconductor crystal grains as constituent, generally the size of hole being 10mum-10mm and the spacing approx. the same as the hole size. This molding 1 contracts when cooled by liquefied nitrogen, and this contraction generates internal stress inside the plate. This internal stress often exceeds the mechanical strength of the molding 1, and in many cases cracks are initiated with no minute holes 2, but provision of holes 2 relieves internal stress and prevents crack initiation.
