Hot Zone of Sapphire Growth

A sapphire long crystal furnace is a device used to grow single crystals of sapphire. Sapphire is a rare gemstone with a beautiful blue color and a high degree of transparency, making it widely used in jewelry and industry.

Sapphire long crystal furnaces gradually grow sapphire seeds into single crystals by placing them in a molten mineral solution at high temperatures and pressures. This process requires very precise temperature, pressure and chemical controls to ensure the quality and purity of the sapphire single crystals.

A sapphire long crystal furnace usually consists of a furnace body, a heating system, a pressure control system, a temperature control system and a crystal growth control system. It can grow sapphire single crystals with diameters ranging from a few millimeters to tens of millimeters, which are used to prepare various sapphire products.

The sapphire long crystal furnace has a wide range of applications, in addition to the growth of sapphire single crystals, it can also be used for the growth of other gemstones and crystals, as well as research and development in the field of materials science and optics.
