Pyrophyllite Cube For HPHT Press Machine
A pyrophyllite cube is a high-temperature, pressure-resistant block made from natural or synthetic pyrophyllite — a hydrated aluminum silicate mineral. It is commonly used as a support and pressure-transmitting material in HPHT (High Pressure High Temperature) presses, especially cubic press machines for synthetic diamond and cBN production
