HPHT stands for High Pressure High Temperature, a method used primarily in the diamond industry to create synthetic diamonds. This process mimics the natural conditions under which diamonds form deep within the Earth, involving extreme pressure and temperature to convert carbon into diamond crystals. In addition to diamond production, HPHT technology is also applied in various scientific and industrial fields. It helps researchers study materials under extreme conditions, contributing to advancements in geology, materials science, and even the development of new technologies.
