grey tin

Grey tin has the same crystalline structure as that of diamond.

It looked like a child's drawing of a car, a grey tin box with squared-off corners and bashed-up fenders.

In cold environments, this can change to α-modification grey tin, which is not electrically conductive, and falls off the leads.

Whichever way you look at it, the NAD remains an uninspiring grey tin.

Then we moved into a dock, lined with warehouses as they appeared, under whose grey tin roofs were stacked bags of grain in large profusion.

Grey tin usually has the appearance of a grey micro-crystalline powder, and can also be prepared in brittle semi-lustrous crystalline or polycrystalline forms.

It was built in 1887, and is a white frame, Gothic Revival style structure with a clipped gable roof of grey tin and a belfry.

This transformation causes ordinary tin to crumble and disintegrate since, as well as being brittle, grey tin occupies more volume due to having a less efficient crystalline packing structure.

At 13.2 C (about 56 F) and below, pure tin transforms from the silvery, ductile metallic allotrope of β-form white tin to brittle, nonmetallic, α-form grey tin with a diamond structure.

Below 18C, white tin will inevitably freeze into grey tin. 2 not even a misleading name 1 Fritzsche first to make them guess at the color suspected cold as the cause of the decay and subsequently proved this by experiment.
