Product overview:

The crucible descending growth furnace is also known as the Bridgman crystal growth furnace. The crystal growth material is loaded in the crucible and slowly lowered. Through a growth furnace with a temperature gradient, the furnace temperature is controlled slightly above the melting point of the material. Melting. When the crucible continues to fall, the temperature at the bottom of the crucible first drops below the melting point and begins to crystallize. The crystal continues to grow as the crucible is lowered.

The detailed information

The crucible descending growth furnace is also known as the Bridgman crystal growth furnace. The crystal growth material is loaded in the crucible and slowly lowered. Through a growth furnace with a temperature gradient, the furnace temperature is controlled to be slightly higher than the melting point of the material. Melting. When the crucible continues to fall, the temperature at the bottom of the crucible first drops below the melting point and begins to crystallize. The crystal continues to grow as the crucible is lowered.

Crystal furnace consists of furnace body, heating system, atmosphere control system, insulation system, transmission system, crucible and seed crystal. This method is often used to prepare sapphire, laser crystal, fluoride and other artificial crystal materials.

According to the requirements of the growing process, high vacuum units or medium and low vacuum units can be selected. The induction mode or resistance heating mode can be selected as the heating method. The high-quality mass flow meter is equipped to ensure accurate control of the growth atmosphere. Both the servo motor and mechanical transmission components Originally imported, the metal static sealing method is used to completely eliminate the air leakage phenomenon during the descending system.

We can carry out joint design and manufacture according to the customer's growth process, and provide process and technical support for growth and processing within a certain range.
