Methods are described to make strong, tough, and lightweight whisker-reinforced glass-ceramic composites through a self-toughening structure generated by viscous reaction sintering of a complex mixture of oxides. The present invention further relates to strong, tough, and lightweight glass-ceramic composites that can be used as proppants and for other uses.
