201966Presently there are few applications of high pressure in the production of new materials or nanomaterials. Historically high pressure synthesis has found few reallife applications beyond manufacturing of diamond and diamondlike materials. The major reason for this is the unstable nature of the high pressure phases at ambient conditions.
