Abstract
Compositions comprising nanoparticles (e.g., nanocrystals) of stishovite silica are described. Such nanoparticles may be made by (1) subjecting a mesoporous silica starting material (e.g., SBA-16 or KIT-6) to a pressure of less than about 20 GPa (e.g., about 12 GPa); (2) heating the mesoporous silica starting material while under pressure to an elevated temperature of less than about 1000° C. (e.g., a temperature of between about 300° C. and about 400° C.); and thereafter isolating the nanoparticles. The nanoparticles may be used in a work tool that is configured and adapted for cutting, drilling, abrading, polishing, machining, or grinding, among other uses.
