Molybdenum boats have a very high heat resistance and mechanical strength. The melting point of molybdenum 2620 °C refractoriness, it is second only to tungsten, rhenium, osmium, iridiu. Molybdenum retains strength at temperatures up to 2000 °C. To 1370 °with its relative thermal strength is higher than that of tungsten. Molybdenum is characterized by minimum thermal expansion coefficient, high elastic modulus, excellent corrosion resistance, allowing it to be used in the most demanding conditions, including in aggressive environment.
The disadvantage is the high production cost of molybdenum boats. Because of the significant hardness and refractoriness molybdenum difficult technological processing. Production it time-consuming, and obtaining it in its pure form is quite difficult. Under normal conditions, it is rigid and not very technological material.
Molybdenum boat are manufactured by hot rolling, riveting, bending from blanks obtained by powder metallurgy by pressing high-quality MCH and MCIT and subsequent machining. Dimensions and tolerances are agreed with the customer. The latest production technology, guarantee the high reliability and temperature resistance molybdenum boats. Pumps are manufactured in a variety of sizes. Price depends on complexity of processing and the additional requirements of delivery.
Molybdenum boat is widely used in electrical, ceramic production in high-temperature installations with hydrogen or vacuum atmosphere for sintering and annealing of powder products from metals and nonmetals, the recovery of oxides of metals, growth of single crystals, melting glass, etc.
