Conversion of Shale and Slate Wastes to Glass and Glass-ceramic Products.
NTIS: PB 82-251976 :32 pages
Experiments were conducted to convert spent oil shale, waste slate, and copper slag into glass and glass-ceramic products. Spent oil shale was easily melted at 1,300 deg. C and converted into glass wool for insulation application. Glass-ceramics were prepared by the use of domestic chrome ore as a nucleating agent. Waste slate from Vermont was readily melted when mixed with limestone. The resultant glass fibers were highly resistant to alkali attack. Iron metal was recovered from copper slags by the use of coal powder as a reducing agent in the molten slag. The lowering of the iron content resulted in a melt that was glass forming. Combinations of spent oil shale and copper slag also yielded useful glass and glass ceramic compositions.
