Making Grey Tin (tin pest)

I take some metallic (white) tin, cool it off, and it converted to the grey allotrope.

  • Is it possible to use tin powder for stannous Chloride solution?

  • This is pretty interesting. I put a glass ampule containing 10 grams of 99.99% tin in the freezer many years ago, it took only a year or so to completely turn into powder. Then I left it untouched, until I saw this video. From what I can tell, it's now an even finer powder than what I remember it to be. I guess the transition was still ongoing in the past few years when I'm not watching.

  • Why is it that, much more than the cold temperature, the presence of "grey tin" aided so strongly in making more of it? It almost seems "disease-like," and I assume that's where the name "tin pest" comes from?! Are there any other applications for this besides your stannous solution? Do you have a use for it, or was it more curiosity that drove you? Thanks Cody .. I don't have a physics or chemistry background, but your videos are really interesting for laypeople! Cheers!

  • Interesting....years ago I seem to remember someone telling me a story about during the war, the Nazi's pursued the Russian's back north, and as it got cold, the shiny tin buttons on the Nazi's uniforms 'turned to powder' and they couldn't keep their coat's closed, so they all froze and had to give up (something like that). I was told 'tin turns to powder at really cold temperatures'. I think I might actually have a much better explanation of what happened now :)

  • Hi Cody, i just graduated collage and i've started my first real engineering job. I was recently educated by the head of engineering that we can't produce ROHS compliant boards because of the threat of forming a "tin whisker". Is the formation of a tin whisker at room temperature just another means of forming the allotrope grey tin?

    Rich St AubinRich St Aubin3 år sedan
    • No tin whiskers are a different phenomena. There isn't a fully agreed on reason for tin whiskers but the most common answer is from the residual stress in the solder joint causing the tin grains to extrude out of the surface when they form certain favorable grain boundary angles with the surface. So most of the methods for mitigating have to do with removing residual stress or alloying to change the grain boundary angles or flow stress of the grains.

  • I also made grey tin in my freezer. My starting material was metallic tin from Rotometals. There seems to be a lot of questions about how pure the tin needs to be for this experiment to work but I found the Rotometals tin sufficient. It also took several years for mine to convert. I had no idea that you could "seed" the conversion with a bit of grey tin. That is very interesting!

  • Here's some notes from an old chemistry book: "The transition point can be detected dilatometrically and lies at 18°-20°. A mixture of the two kinds of tin neither contracts nor expands at this temperature, while at higher temperatures a contraction is observed and an expansion takes place on cooling, due to the disappearance of the grey tin on heating and of the white tin on cooling. The same transition point is found if electrodes of grey and white tin are placed in a solution of a tin salt and the resulting potential difference followed. At about 20° this is zero, but below this temperature white tin, and above it the grey variety, has the greatest solution pressure [i.e. EMF]. As the ordinary temperature in temperate climates is usually below 20° it follows that all tin is in the metastable condition except on a few very warm days; and it is only because the rate of transformation is so slow that the tin remains unaltered on most occasions. This pseudo-stability disappears at once if the tin is placed in a solution of a tin salt. The deposition of tin takes place owing to the small currents set up by differences in concentration in the solution, and the tin is naturally deposited in the form stable at the temperature of the experiment. The small amount of grey tin which separates out at temperatures below 18° is enough to infect the whole mass of tin. The rate of transformation is thus markedly affected by the presence of tin salts, and whereas dry tin shows a maximum rate of change at -48°, when immersed in a solution of a tin salt the change is most rapid at 0°. The previous history of the tin also affects the rate of transformation, and a sample which has been undercooled for a long time is converted into the grey form much more rapidly than tin which has not undergone this treatment. Again if some grey tin is transformed into white and then back again into grey, the second change takes place more quickly than with fresh tin, and the more often the tin has been transformed the more rapidly the change takes place. Even the transition temperature is affected by a repetition of experiments or by intermediate heat treatment; with cadmium it can be depressed from 70° to 62°." (Temperatures are degrees Celsius.)
