Special requirements of the profiled Molybdenum Products

 1, easily oxidized Molybdenum crucible products have properties. Severe oxide to be removed, with a strong acid (hydrofluoric acid, nitric acid, hydrochloric acid, etc.) processing, the operation note.
    2, mild oxide abrasive cleaning agent using the Add, with a soft cloth or sponge to wipe, then wash with warm water.

 Tungsten Tungsten Molybdenum subsidiary of Hong Lu Industrial Co., Ltd. on April 26, 2012 successfully developed China's first spinning molybdenum crucible, the process and technology in the application of molybdenum crucible is a domestic leading level, breaking the product only by foreign companies supply situation, and create a precedent for domestic molybdenum crucible spinning. The products and projects for the Chinese domestic sapphire crystal needed for the production of high quality molybdenum crucible to provide strong protection.

    According to the author at: Molybdenum Crucible is the use of Mo-1 production from molybdenum powder, temperature at 1100 ℃ ~ 1700 ℃. Mainly used in metallurgical industry, rare earth industry, silicon, solar, artificial crystal and mechanical processing industries. And its main physical characteristics are as follows 1, purity: W ≥ 99.95%; 2, density: ≥ 9.8g/cm3; 3, maximum application temperatures: 2400 ℃.
    The main production process: molybdenum powder - sifted - combined batch - isostatic pressing - rough blanks lathe - IF Sintering - Boutique vehicle processing - packaging. Since the melting point of the main purposes of molybdenum up to 2610 ℃, therefore molybdenum crucible is widely used in sapphire crystal growth furnace, quartz glass melting furnace, rare earth smelting furnaces and other industrial furnace core container, the use of working temperatures generally above 2000 ℃ . Especially for sapphire crystal growth furnace, it has a high purity, high density, without internal cracks, size precision, smooth inner and outer walls, and other characteristics of molybdenum crucible for sapphire crystal growth process seed success rate, pulling quality control, life off the crystal stick pan and played a key role.
