PRODUCT INFORMATION

What is the Bridgman method?

The Bridgman method involves heating polycrystalline material in a container above its melting point and slowly cooling it from one end where a seed crystal is located. The melted material moves through a decreasing temperature gradient and forms a single crystal. MSE Bridgman furnace has vertically geometry and three zones. The middle zone of the Bridgman furnace is hot.

The reactor can be brought from the upper zone or bottom zone to the middle hot zone of the Bridgman furnace, and it can also be retracted from the place where it is brought.

The inner cabin of the Bridgman furnace consists of graphite insulations and graphite resistances. The sample dissolved in the graphite reactor can move to the cold zone at very slow speeds, whereby the crystal occurs.

In this method known as the Bridgman method, all parameters are adjusted by means of a touch panel. During the process, the reactor position, reactor speed, thermocouple temperatures, atmospheric pressure can be monitored and recorded on the Bridgman furnace monitor.

APPLICATION NOTES

For the maximum life of the furnace and the longer use of the furnace equipment, we recommend that the heating rate of 10°C/min . Flammable and explosive products must not be used in the furnace.

The hydrogen gas usage inside the furnace must not exceed %8 and must used as mixture gas The flowmeter which included the furnace are not only manual but also not high sensitive. For the high sensitive ones please get in touch.

Gas, water source, furnace connections and connection equipment are to customers responsibility. The vacuum pump which is including the system, for the purpose of purge the air that can not be work for proper vacuum condition. To have a vacuum condition please contact us.
