ABSTRACT:
A strontium or barium carbonate product that is better suited for use as a glass ingredient is obtained by sintering the powdered carbonate in a kiln lined with fused amorphous silica. The carbonate picks up fewer harmful contaminants from the amorphous silica lining than it does from, say, a refractory silica-alumina brick lining or a kiln having a metallic inner surface.
