..., zinc is available as slabs, ingots, shot, powder, and dust; combined with oxygen, it is available as zinc oxide powder. Slab zinc is produced in three grades ( Table 1 ). Impurity limits are very important when zinc is used for alloying purposes. Exceeding impurity limits can result in poor mechanical...

.... There are many examples, including the opening of grain boundaries in creep in such materials as nickel-base superalloys and superplastic forming in aluminum-zinc alloys. From these arguments, it follows that the metallurgical features, such as the grain boundaries alone, cannot be the origin of the...

... substantial amounts of zinc are subject to “flaring,” the volatilizing of zinc from the melt. The zinc vapor instantly reacts with oxygen in the atmosphere, forming zinc oxide, a white powder that is easily visible to the melter. Aluminum additions help control flaring.
