Abstract
Methods are described to make strong, tough, and/or lightweight glass-ceramic composites having a crystalline phase and an amorphous phase generated by viscous reaction sintering of a complex mixture of oxides and other materials. The present invention further relates to strong, tough, and lightweight glass-ceramic composites that can be used as proppants and for other uses.
