Abstract
An amorphous substance has a nominal composition expressed by a general formula of Ba(B.sub.1-x M.sub.x).sub.2 O.sub.4 (where M is at least one element selected from the group consisting of Al and Ga, and 0.05<x<0.20).
Claims3
An amorphous substance having a nominal composition expressed by a general formula of Ba(B.sub.1-x M.sub.x).sub.2 O.sub.4 where M is at least one element selected from the group consisting of Al and Ga, and 0.05<x<0.20.
A process of making an amorphous substance having a nominal composition expressed by a general formula of Ba(B.sub.1-x M.sub.x).sub.2 O.sub.4 where M is at least on element selected from the group consisting of Al and Ga, and 0.05<x<0.20, comprising the steps of melting a crystalline raw substance having said nominal composition to obtain a melt and rapidly cooling the melt of the raw substance down to 680-720.degree.
