Molybdenum is a crucial element of life. In humans, there are over 60 Molybdenum enzymes in the human body. Humans also have Tungsten substituted for Molybdenum in similar enzymes that work in concert together. In the sea, a vast number of organisms depend on one or both of these metals whereas a deficiency of either usually has lethal consequences for simple sea life. This has been a problem in the adaptation certain types of specialized sea bacteria into freshwater lakes in California as the sea contains massive amounts of trace minerals. In humans Molybdenum levels are highest in the liver, kidneys and adrenals. While a deficiency of molybdenum is rare in humans, excessive copper intake can cause it.
That is true. Molybdenum is even supposed to be related to life formation, that may have begun on Mars (and then delivered to Earth via meteorites). This has to do with Mo-S clusters, but also Fe-S clusters. Similar clusters may have been derived from some Fe-S minerals, like greigite.
Molybdenum Disulfide is my go-to lubricant for metal to metal contact applications, especially when high heat is involved. MD actually bonds to the metal and creates a nearly frictionless surface. I was having trouble with the sleeve bearings in the motors of the exhaust fans of my furnaces. I mixed some MD with some very light oil and let it wick into the bearings. They now run very smooth, very quiet and haven’t given me any problems for years. I have used it when assembling R/C aircraft engines and other high speed/high heat applications. It’s amazing stuff and I can’t say enough about it. It can be added to oil, grease or applied directly. You can even use a solvent, such as isopropyl alcohol, if you want it ‘carried’ into a close metal to metal application, and only leave the MD behind. It’s expensive in powder form, but just a little goes a very long way. (I have a one pound container, I’ve used it for over 25 years and I’m nowhere close to using it up.) It looks a lot like graphite, but has a much lower friction coefficient. Also, wear gloves while using it. The particle size is so small, that it will actually penetrate and bond to your skin, leaving stains that won’t readily wash off. I wish that I had a spare automotive engine to test it on. I would just add it to the oil and let it coat everything. My only concern, even though the particle size is very small, is that it might clog the oil filter. I suppose that I could let it run for a short while, change the oil filter and see how that works. It would be an interesting experiment to try. Does anybody live in northern Illinois USA, have a spare low-mileage engine and want to try this? We could take all sorts of measurements, treat the engine with MD and then repeat all of the measurements. It would make for a great video! We could even create an engine additive, give it a cool name like ‘Slick As Fuck’, sell it in stores and make a fortune. LOL :-)
I'm sorry, but Liquimoly beat you to it with their MoS2 engine oils and additives, lol. At least I found your favourite motor oil and you won't have to worry about it clogging up your filters.
"Molyslip" has been around for ages, and if I recall, NEVER use it on too low mileage an engine, as it can tighten the tolerances, so any possible high spots must have been worn in first.
Molybdate anion is a good test for dissolved silica in the form of metasilicate or silicic acid, and will detect a few parts per million of it. To a solution of silicate, add some ammonium molybdate solution followed by dilute acetic acid in excess. Over several minutes, a yellow colour will develop, which is a complex anion of silicon-molybdate or molybdo-silicate. The strength of the yellow colour can be measured with a spectrometer and it is a quantitative measure of silica if run with a standard. Now add some crystals of hydroquinone, and the solution turns a beautiful blue.
I wish you had talked about the importance of Molybdenum in WWI. The mining of Mo in the United States by German spies allowed the production of superior artillery like Big Bertha. Mo gives steel a higher thermal resistance allowing for the increase in shell sizes.
U r really awesome ... Thank you Soo much for these videos... U helped me Soo much in exams ... Thank you bro... Ur idea of making videos on elements is awesome.. please keeps on doing ...
Obviously the proper name for the black colored form is chemical X. Drink it and you'll become a powerpuff girl (disclaimer to reader, dont actually do this. I trust most of you wont or cant, but to those who can and think this is a good idea, dont.)
With low speed deformation, Molybdenum is quite ductile and malleable. I can bend or extend Mo easily but not a case in W. It's another story in high speed impact, though.
1:22 - units mismatch Pure Mo metal has high hardness and is brittle (like Chromium) making it unsuitable for most applications. However its widely used as alloying element with Nickel/Iron/Cobalt bases.
I know this element Mo is in my materials we buy and machine. That is all I know so lets listen and learn what it is also used for and why? Thank you for the videos they are very educational to us. Same colors through heat like we get in our experience with titanium. Like the Molybdenum blue color a lot.
Greetings, Mr.Maxim Bilovitskiy what a fascinating video of yours indeed Molybdenum is a weird Element, and watching it form solutions was interesting and mind-blowing, and watching the video was fascinating fulfilled with needed information about the Element, keep up the good work Best of Luck. Note: I would like to know what camera are you using to film your videos because I opened my channel back when I was 12yrs old teaching chemistry but until now I don't know what type of camera to use but after watching your videos iv decided to get one like yours if you don't mind would you inform me what type of camera are you using. Thank you From: ( AP Chemistry course)
There isn't much between the molybdenum complex shown and some copper oxidation states. Would be interesting to see how the electronic splitting occurs
Look up the movie THE BROTHERS O'TOOLE with John Astin. The gold miners thought they were broke because there was no gold in their claims, only Molly-be-damn.
Hey! So I'm actually in a quest to find a way to titrate a Molybdate solution to find the concentration of Molybdenum ions in solution. Would you have a suggestion or a clue to continue searching?
Molybdenum is also good in refining because of its ability to help resist HTHA (High Temperature Hydrogen Attack) that can destroy regular carbon steel over time.
I would like add that molybdenum is the most radioisotope used in the nuclear medicine. Its produce in experimental nuclear reactors through the uranium fission
I bought a bag of tungsten disulfide sulfide powder online and saw complaints that it was Molybdenum instead. How can I test to see which it is? Thanks
I work with this metal in manufacturing metal catalysts for oil refining. It's never the sole metal used in catalysts to which we add other metals with it. The two metals that's used with this is either Nickel or Cobalt. (NiMo) or (CoMo).
The way Tolstoy, mashes through the English language during his 20 minute speech. Is enough destruction to stop the advancement of science at one sitting. I can still hear him grinding away, even after the video has stopped! He truly is the painful Russian!
