METHOD FOR PRODUCING AL-DOPED GADOLINIUM OXYSULFIDE COLD STORAGE MEDIUM
Provided is a cold storage material having a large thermal capacity in a ultra-low temperature range of 10 K or less and being highly durable against thermal shock and mechanical vibration. The cold storage material contains a rare earth oxysulfide ceramic represented by the general formula ROS (wherein R is one or more kinds of rare earth elements selected from La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y), and AlOhaving a specific surface area of 0.3 m/g to 11 m/g is added to the cold storage material.
