Periodic Mesoporous Phosphorous (V)-oxyimide
SUMMARY Stishovite is the hardest oxide material known and because it is an oxide, it is resistant to corrosion. It can be incorporated into machine tools for processes such as cutting and grinding, and can be used for polishing applications. However, the cost of making Stishovite has inhibiting greater adoption. Lehigh University has addressed th...
