Tungsten crucible applications: Pure tungsten crucible applications are contain of vacuum inert gases below 2600 degrees. Tungsten has high melting and boiling point, high temperature strength, resist corrosion, high thermal conductivity, small thermal expansion coefficient, good hardenability, so tungsten is widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth

Molybdenum is used as an alloying addition in steels, and molybdenum and its alloys are used for electrical and electronic parts, missile and aircraft parts, high-temperature furnace parts, die casting cores, hot-working tools, boring bars, thermocouples, nuclear energy applications, corrosion-resistant equipment, equipment for glass-melting
operate at the same vacuum levels as the furnace with a metal hot zone because graphite is a hygroscopic material. Generally, graphite furnaces heat more slowly compared to an all-metal hot zone furnace. Braze Joint Design Clearance For Vacuum Furnace Brazing Clearance is the distance between the surfaces of the joint at brazing temperature.
most popular high temperature crucible furnace. Home; Vacuum furnace equipment; Top 10 Ways to Maximize Crucible Service Life | Foundry . In a fuel-fired furnace, operating the burner with excess air and direct flame impingement on the crucible surface will produce damaging oxidation of the crucible.
Molybdenum-98 is the most abundant isotope, comprising 24.14% of all molybdenum. Molybdenum-100 has a half-life of about 10 19 y and undergoes double beta decay into ruthenium-100. Molybdenum isotopes with mass numbers from 111 to 117 all have half-lives of approximately 150 ns.
201639Vacuum furnaces are available in numerous styles and sizes and come in both standard and custom configurations. They are designed to process an almost limitless number of both semi-finished component parts as well as raw materials using a diverse set of thermal processes in equipment available from a wide variety of different equipment manufacturers located around the world.
These crucible furnaces can be used for melting aluminium, copper, brass and in fact most nonferrous metals. In the electric range of crucible furnaces that silcarb manufactures the heat source usually is the silicon carbide heater which is manufactured in house.
