Sapphire Furnace Tungsten Products

Pure tungsten and molybdenum products as an important material for sapphire growth furnace. Sapphire furnace with pure tungsten products mainly purity higher than 99.95% of the raw materials made ​​of tungsten products, including tungsten crucible, tungsten plate, tungsten sheet, tungsten wire, tungsten electrode screen, tungsten and tungsten tube heat shield. Among them, Tungsten rhenium wire is produced as the main material of tungsten alloy wire, common specifications for the rhenium-containing 25% tungsten rhenium wire.

Sapphire furnace with pure tungsten product is steel-gray to tin- white hard metal , very pure tungsten can see-saw sawing ( pure tungsten is very brittle and difficult to process ) . Tungsten processing means are forging, tensile and impact . In all the highest melting point of tungsten metal for 3415 ℃, the lowest vapor pressure at the highest tensile strength (1650 ℃ when ) . Corrosion performance is very good , most of the erosion of its small inorganic acids . In the air to form a protective surface oxide , but will be completely oxidized at high temperature .

Sapphire (Sapphire) is an aluminum oxide (α-Al2O3) single crystal , also known as corundum , sapphire crystal as having excellent optical properties, mechanical properties and chemical stability , high strength, hardness, resistance to erosion, can be close to 2000 ℃ high temperature work under harsh conditions , they have been widely used in military infrared devices , satellite space technology , high-intensity laser window material its unique lattice structure , excellent mechanical properties, good thermal properties make sapphire crystal GaN/Al2O3 a practical application of the semiconductor light-emitting diode (LED), large scale integrated circuit and the SOS SOI nanostructured superconducting films and the ideal substrate material .

tungsten-sheet-and-sapphire

Sapphire growth furnace designed to nurture through Kyropoulos sapphire single crystal . This method is the tungsten crucible by the raw materials ( alumina ) was heated to its melting point of 2050 ° C or more, and then gradually reduce the melting temperature and allowed to crystallize into a specific granules . The growing furnace in a heat-insulating casing with a special lid closed and the heater constructed in crystallizer . Therefore, there has been a pure sapphire furnace with tungsten products.

Pure tungsten material because of its high temperature resistance, corrosion resistance, sapphire crystal dissolution phenomena such infiltration occurs , and thus become the most popular sapphire growth furnace materials .
