Due to the manufacturing advantages of tungsten rods, tungsten sheets, tungsten machining parts and tungsten processing equipment, Sunstone established a Division of hot zone of sapphire crystal growing since 2008. Until now Sunstone provided a large number of hot zone parts like crucibles, sheet and rods to Russia, Ukraine, USA, Japan, Korea, Thailand, Singapore Taiwan and Hong Kong. So now we have been gradually formed the capacity of 30 sets hot zone in 35Kg, 65Kg, 85Kg and 120Kg. Sunstone has a sound quality management system of ISO9001 and ISO14001 and get the certification. Sunstone has a excellent testing equipment of physical properties like density, hardness, surface roughness, grain size, tensile strength and other parameters, even ultrasonic NDT. The distinguishing characteristic of Sunstone 's tungsten crucible is high density, high purity and high precision machining. As the whole set of hot zone parts is completed in Sunstone , so the quality between the components is to get a good guarantee. With its excellent quality and reasonable price has been widely recognized by the industry of sapphire crystal growing and hot zone furnace at home and abroad, Sunstone has been designated the sole supplier and leader in domestic and foreign industry. Because of their excellent corrosion resistance again sapphire melt and their high temperature creep resistance, tungsten crucibles are used for sapphire crystal growing in all common processes.

Sintered tungsten crucible Sintered with tungsten powder the sintered tungsten crucibles are multi-purpose production in sintering furnace, large crystal growth furnace. Thickness of sintered tungsten crucibles is usually 8-12 mm; diameter is typically 100-550 mm; height is typically 50-700 mm. Such crucible Purity: W �?� 99.95%; density is usually up 18.2g/cm3, by special needs the density can up 18.8g/cm3 or more. Features: 1.The overall density of sintered tungsten crucible is fairy high between 18g/cm3 to 18.3g/cm3; 2.Its chemical purity of sintered tungsten crucible can be above 99.95%; 3.The diameter of sintered tungsten crucible can be above 200mm; 4.The surface roughness of tooled crucibles does not exceed Rz 6.3; 5.The use temperature of sintered tungsten crucible should be below 2450�C in vacuum or deoxidize atmosphere. 6. The shapes and dimensions of crucibles are also made in accordance with customers' requirements. material density size W >99.95% 18g/cm318.3 g/cm3 Diameter: 100-550mm; Height:50-700mm Stamped tungsten crucible The tungsten crucibles can be produced of a tungsten plate by stamping, spinning, or welding. It can be used to produce single-use square or round crucible. Thickness typically 0.5 to 3 mm. Such tungsten crucible Purity: W �?�99.95%; density is usually up 19g/cm3 Forged tungsten crucible The tungsten crucible can be made of tungsten rod by turning , generally they are smaller and with higher density. Usually the wall thickness 3-10 mm; diameter of 80 mm. They are widely used by sintering furnaces for ceramics and other materials or vacuum evaporation coating machine. Purity: W �?� 99.95%; density are usually based on different diameters of up to 18.3 to 19g/cm3 Notice: 1.Before use, it is recommended that the consumer anneal (de-gas) crucibles in a vacuum without batch charging; 2.In a furnace, the annulment process should be supported with a vacuum at P< 10-3mmhg; 3.When preparing a sintered tungsten crucible for work, the consumer should not allow a sharp rise or fall in temperature, or abbreviate the recommended time periods for holding temperatures. Applications Tungsten crucible is mainly used used for rare earth,sapphire single crystal growth furnace , quartz glass, Metal extracting, metallurgical industry, machinery processing, glass and ceramic industries, etc.

99.95% Pure Tungsten Products Tungsten Crucibles W Crucible for Sapphire Growing Because of the high melting point(3410) of tungsten, tungsten crucible is widely used in the industrial furnaces such as sapphire single crystal growth furnace, quartz glass melting furnace, rare earth smelting furnace and other industrial furnaces of which the working temperature is over 2000â??. Especially for sapphire single crystal growth furnace, tungsten crucible with features of high purity, high density, no crack, precise size, smoothy internal and external wall is the key note to seed success rate, crystal quality control, off crystal stick pan and service life in sapphire crystal growth process. During sapphire production, Al2O3 - the compound that is to become the future single crystal - is melted in tungsten crucibles. It is in the Kyropoulos process that our crucibles show their strengths to best effect. They arerepeatedly heated to more than 2 000 �°C (3632 �°F) and then cooled down again. This process, which would cause fissures and distortions in other materials, is not a problem for our products.
