Is mosi2 a ceramic?
Molybdenum disilicide (MoSi2, or molybdenum silicide), an intermetallic compound, a silicide of molybdenum, is a refractory ceramic with primary use in heating elements. It has moderate density, melting point 2030 °C, and is electrically conductive.
What is mosi2 used for?
Molybdenum disilicide (MoSi2), a refractory metal silicide, is mainly used as a heating element. Of late, it has been recognized as a potential structural ceramic, since it exhibits high elastic modulus and exceptional oxidation resistance at very high temperatures.
Why do we need silicide?
Why use silicides? Low resistance • Good process compatibility with Si, e.g., ability to withstand high temperatures, oxidizing ambients, various chemical cleans used during processing. Little or no electromigration • Easy to dry etch • Good contacts to other materials.
What are 5 uses for molybdenum?
Most molybdenum is used to make alloys. It is used in steel alloys to increase strength, hardness, electrical conductivity and resistance to corrosion and wear. These ‘moly steel’ alloys are used in parts of engines. Other alloys are used in heating elements, drills and saw blades.
What is the main advantage of Salicide process?
These silicides have fairly low resistivity and good high-temperature-stability. The self-aligned-silicide (salicide) process is widely used in integrated circuits to reduce polysilicon gate resistance and source/drain contact resistance. The self-aligned-silicide technology possesses a number of advantages.
Where can I find molybdenum?
The main molybdenum ore is molybdenite (molybdenum disulfide), but can also be found in wulfenite (lead molybdate) and powellite (calcium molybdate). It is recovered as a by-product of copper or tungsten mining. Molybdenum is mined primarily in the United States, China, Chile and Peru.
Is molybdenum a heavy metal?
Molybdenum is a transition metal in Group 6 of the Periodic Table between chromium and tungsten. Although molybdenum is sometimes described as a ‘heavy metal’ its properties are very different from those of the typical heavy metals, mercury, thallium and lead. It is much less toxic than these and other heavy metals.
What is MoSi2 ceramic used for?
Molybdenum disilicide (MoSi 2) ceramic has been extensively investigated and used for high temperature heating element applications due to its high melting temperature, high thermal and electrical conductivities, excellent oxidation resistance and corrosion resistance [ [1], [2], [3] ].
What is MoSi2 heating?
Sentro Tech manufactures Molybdenum disilicide (MoSi2) heating elements for industrial and laboratory furnaces. A ceramic-based resistant element, the MoSi2 heating elements produce furnace temperature to 1800°C.
Are MoSi2-UHTC ceramics suitable for heating elements?
MoSi 2 based ceramics have great potential for high temperature heating element applications. In this paper, MoSi 2 -UHTC ceramics were produced by pressureless sintering by introducing 0, 20 and 40 vol% UHTc (ZrB 2 -20 vol% SiC) as additives.
Can pressureless sintering produce MoSi2-UHTC ceramic?
MoSi 2 based ceramics have great potential for high temperature heating element applications. In this paper, MoSi 2 -UHTC ceramics were produced by pressureless sintering by introducing ZrB 2 -20 vol% SiC ultra high temperature ceramic as additives.
