Molybdenum crucible is very resistant to acids such as hydrochloric, hydrofluoric and sulfuric. Because it has a very high melting point of 2617°C, molybdenum crucible is used for high temperature situations. It does not easily melt even when subjected to very high temperatures. Molybdenum crucible comes in standard capacities of 20 ml to 100ml.Manufacturers can also customize size and capacity according to client requirements.
Some examples of molybdenum crucible that are used for high-temperature furnaces are welded crucible, spinned crucible, square crucible and forged W and Mo crucibles.
Molybdenum crucible is often used in the metallurgy industry. It is an indispensable material often needed in the smelting industry, manufacture of crystalloid materials and new technologies. Because it is more resistant to thermal shock, it performs better than crucibles made of ceramic.
2. Solar Industry
In the solar industry, molybdenum crucible is also used for the growth of silicon single crystals. The crystals have to be repeatedly heated in temperatures often exceeding 2,000°C (3632°F). If the crucible is not made of the right material, the quality of the crystals will be affected and fissures or distortions may result.
3. Production of Sapphire Crystals
There is currently a remarkable growth in the furnace industry, specifically furnaces that are used for producing sapphire crystals which are used in LED manufacturing. These furnaces require a solid hot zone design and often use molybdenum crucible which has high thermal conductivity. The crucibles made of molybdenum and tungsten alloy are excellent in strength and remain stable even at temperatures above 2,000°C.
The molybdenum crucible that is used for sapphire production must have a smooth surface, high material density and resistance to corrosion and high temperature. When sapphire is melted, it can easily cause corrosion if the crucible material is not of high quality. The crucible must have a low surface roughness, so that the sapphire can be easily extracted. Using the right vessel for sapphire production can result to a more cost-effective and high quality product.
4. Other Applications
Because of the high melting point of molybdenum, it is an excellent material for vessels that are used for high temperature applicationssuch as processing of nuclear pellets. The high strength of molybdenum and its alloys can create a vessel that can withstand rough handling and repeated exposure to high temperature. It can also withstand many molten materials such as glass, metals and other compounds.
These are just some of the industries that depend on molybdenum crucible in the manufacture of their products. As more advanced technologies are being developed, molybdenum will continue to be a chosen element for manufacturing and other industries, because of its unique properties.
