Featured here is a tungsten heating element with a birdcage structure. The cage structure heating element uses tungsten or tungsten mesh heating element and help to provide a uniform and stable temperature field. The tungsten heater block assembly act as sapphire crystal growth furnace heat source to melt the tungsten crucible turbulence, a radial temperature gradient has a decisive role. Therefore, with high purity, high density, well-made, well-designed tungsten heating element assembly quality sapphire crystal control, energy conservation.
