Product Description Product DescriptionMaterial Description Tungsten crucible is made of metal tungsten. Tungsten has the characteristics of high melting point, high strength and hardness, good performance at high temperature, low resistivity, small expansion coefficient, and small electronic work function; therefore it is an important part of sapphire crystal growth furnace. Tungsten crucible products of our company have been used by more than 100 sapphire crystal growth factories and quartz glass factories for many years, and won excellent reputation and feedbacks. Areas of ApplicationAs containers used in high temperature , tungsten crucibles are widely used in sapphire crystal growth, rare-earth smelting, and coating industries. Product SpecificationsCISRI-AT&M has 30 years of experience in producing tungsten crucibles and can meet all your requirements.1. General density: 17. 8 g/cm3~18. 3 g/cm3;2. Density after special process: higher than 18. 5 g/cm3;3. Maximum outer diameter is up to 700mm;4. We can customize products as your per need and meet all your requirements.Note: For all specifications, we are able to adopt machining method to meet customers' high precision requirements. Production ProcessAccording to different dimensions and conditions of use, tungsten crucibles have different production processes. Crucibles generally have shapes such as round, square, rectangular and V-shape. Producing processes include sintering, welding, stamping, and spinning; in which sintering is used most widely.For micro or small tungsten crucibles,forged tungsten rods lathing or stamping process can be used. Tungsten welding process needs rolled tungsten plates to be hot bended and then weld it to fix. Spinning process is mainly used for producing thin-walled tungsten cr ucibles which have high technical requirements.
