Product Description

HPHT Cubic Hydraulic Press is the equipment that offering pressure and temperature needed for synthesis of superhard material, industrial diamond, large single crystal, Gem diamond and CVD diamond color changing, which produces ultra-high pressure through hydraulic system and high temperature through high-power current . It is also the equipment widely used in national superhard material industry . It is the equipment which is widely used in used in producing super hard material , researching high pressure physics , limiting material and geophysics.

Diamond sintering requires the application of extreme heat and pressure. Typically, diamond is sintered at a temperature of around ***0°C (***0°F). 
HPHT cubic press consists of six large pistons, each of which is capable of supplying several thousand tons of force. Each piston pushes on a small tungsten carbide anvil, which in turn compresses a cubic pressure cell that contains the raw materials (carbide and diamond crystals). As soon as the cubic press reaches the desired pressure, electric current flows through a resistance heater embedded in the pressure cell to generate the required high temperatures. These conditions are maintained long enough to ensure complete diamond-to-diamond bonding of the individual crystals.
