Molybdenum Crucible <br>Molybdenum crucible is widely used in metallurgy, chemical industry and rare earth manufacturing enterprises as a container for melting metals and alloys. In recent years, with the more and more serious pollution caused by the use of traditional resources in China, the development of new green energy has become a top priority, which is more obvious in the monocrystalline silicon, polycrystalline silicon, sapphire preparation industry. The new energy raw materials such as silicon and sapphire are prepared at very high temperature, so molybdenum crucible with very high temperature resistance is usually used. <br> <br>Specification of Mo Crucible <br>Forge molybdenum crucible <br>Purity Density Sizes Tolerance Wall thickness roughness <br>99.95% ≥10.1g/ cm3 Dia(mm): Height(mm): Dia: Height: 4-20mm Ra=1.6mic <br> 10-500 10-750mm +/-5.0mm +/-5.0mm <br> <br>Sinter molybdenum crucible <br>Purity Density Sizes Tolerance Wall thickness roughness <br>99.95% ≥9.8g/ cm3 Dia(mm): Height(mm): Dia: Height: 8-20mm Ra=1.6mic <br> 10-500 10-750mm +/-5.0mm +/-5.0mm <br> <br>Sintering and Mechining <br>Purity Density Sizes Tolerance Wall thickness roughness <br>99.95% ≥9.8g/ cm3 Dia(mm): Height(mm): Dia: Height: 8-20mm Ra=1.6mic <br> 10-450 10-450mm +/-5.0mm +/-1.0mm <br> <br>Purity(%) Ag Ni P Cu Pb N <br> &lt;0.0001 &lt;0.0005 &lt;0.001 &lt;0.0001 &lt;0.0001 &lt;0.002 <br> Si Mg Ca Sn Ba Cd <br> &lt;0.001 &lt;0.0001 &lt;0.001 &lt;0.0001 &lt;0.0003 &lt;0.001 <br> Na C Fe O H Mo <br> &lt;0.0024 &lt;0.0033 &lt;0.0016 &lt;0.0062 &lt;0.0006 &gt;99.97 <br> <br>Application of Molybdenum Crucible <br>Since the melting point of molybdenum is as high as 2610℃, molybdenum crucible is widely used in the core vessel of sapphire single crystal growth furnace, quartz glass melting furnace, rare earth smelting furnace and other industrial furnaces, and its working temperature environment is generally above 2000℃.

So as refractory materials, chromium can be to used for furnaces and non-ferrous metal smelting furnace lining. Chromium is one of the world&#039;s most of hard metal. Chromium is often mixed into steel to make a hard and corrosion-resistant alloy. Most of the world&#039;s chromium, are used to produce various kinds of alloy. Stainless steel contains more than 12% chromium (some contain 13% chromium and 8% nickel). Stainless steel has excellent toughness and mechanical strength. <br> <br>Production Process of Chromium Metal <br>The method of producing electrolytic chromium from electrolytic chromium monoammonium and alum aqueous solution was reported many times from 1946 to 1950. The semi-industrial test was completed and the production technology of electrolytic chromium was established. In 1932, a. e. van Arkel reported that high purity chromium (Cr99.99%) was obtained by thermal decomposition of cr iodide for special use. China began to develop chromium metal in 1958. Jinzhou ferroalloy Plant was built into China thermite Chromium Metal Production Plant on the basis of semi-industrial experiments in the early 1960s. In order to reduce the chromium damage and improve the chromium recovery rate, the method of chromium hydroxide was used to produce chromium oxide. In 1959, electrolytic chromium was produced by chromium-ammonium alum aqueous electrolysis method in Jilin Ferroalloy Factory. <br> <br>Features of Chromium Metal <br>01. <br>Chromium is a brittle metal can not be used as a metal material alone, but with iron, nickel, cobalt, titanium, aluminum, copper and other components of the alloy, it becomes a thermal resistance, thermal strength, wear resistance and special properties of engineering materials. <br> <br>02. <br>Chromium metal is used as an alloying agent in the production of various nickel or cobalt-based superalloys, titanium alloys, aluminum-based alloys, resistance alloys, and copper alloys. <br> <br>03. <br>Some are used to produce stainless steel and heat-resistant steel. These materials are widely used in aviation, aerospace, nuclear reactor, automobile, shipbuilding, chemical, military and other industries. <br> <br>We can provide kinds of chromium metal for sale, if you want to buy chromium metal, please contact us. <br> <br>As a refractory metal company, we will do our best to meet all the needs of customers. <br> <br>[a]https%3A%2F%2Fwww.hsgmetal.com%2Fproducts%2Fchromium-metal%2F[/a]
