Bridgman Furnace for Single crystal alloy formation | cyky

Bridgman furnace with the maximum temperature of 1500℃. It is designed for the directional solidification of Polycrystalline Ingots up to 25mm diameter. The heating module & cooling fan with adjustable speed is beneficial to create a large temperature gradient at the interface of the molten / crystalline state. An automatic crucible retrieving system enables the most convenient way for sample loading/unloading. The optional crucible rotation stage can be added at additional cost for single crystal ingot growth.

Bridgman Furnace

Bridgman furnace uses:

The equipment is a single crystal superalloy directional solidification equipment integrating high-temperature alloy smelting, pouring, mold shell double-zone heat preservation, and directional solidification. The equipment is mainly based on experimental research, taking into account small-scale industrial demonstration research;
1.2 The single crystal preparation technology used is the seed crystal method and the crystal selection method; the directional solidification technology used is the high-speed solidification method (HRS) and the liquid metal cooling method (LMC);
