Molybdenum boat fuel sintered high-temperature resistant container

At present, domestic molybdenum boat manufacturers used for drawing fine wires mainly use vertical melting strips and sintered strips.

 After several years of practice in producing molybdenum bars, we believe that the main focus is on strip crystals β Ammonium molybdate has a better effect as a material for further processing of vertical melt strips produced by reduction and pressing using roasting technology. Currently, molybdenum strip manufacturers in China often use this material as a material for drawing fine wire molybdenum strips. In addition to crystal tracing, the content of main elements such as potassium and sodium, physical properties such as porosity and particle size need to meet specific requirements and maintain relative stability.

Special care should be taken during low-temperature sintering of pressed billets. Due to the brittleness of molybdenum, the billets cannot be suddenly cooled or heated. Regardless of sintering or cooling, there should be a temperature buffer zone to prevent fracture. The time and temperature of low-temperature sintering should be controlled well, so that the billets can not only remove low-temperature impurities, but also enhance strength and conductivity, which is conducive to vertical melting processing.

Mainly used in coating technology, electronic industry, power engineering, such as vacuum thermal evaporation (stamping evaporation boat), capacitor sintering, nuclear combustion sintering, thermocouple shells, etc. It is actually a high-temperature resistant vessel that can be used in vacuum furnaces and glass melting furnaces. Compared to molybdenum crucibles, which have a simple structure and low cost, molybdenum boats are commonly used in high-temperature heat treatment industries, such as vacuum furnaces, ammonia furnaces, industrial furnaces, and other high-temperature furnaces as material containers.
