What is "impurities"

Usage examples of "impurities".

Only systems shattered by novas contained the purralinium with the impurities that could be used for matter transmission.

But I am now absolutely positive that the purralinium they are willing to trade us has the impurities we so urgently need.

Carialle recorded that number in her files in case there were any impurities in the final product.

The bauxite impurities (silica, iron oxides, and titanium dioxide) are less soluble and to some degree are filtered out, using cloth filters, as a "red mud.

The other principal impurities in "primary" aluminum are titanium, vanadium and manganese.

That may mean that before we can make, say, aluminum-manganese alloys, we have to develop manganese refining technology to the point that we have a consistent material free of impurities which could adversely affect the properties of the alloy.

If you are making wrought alloys, impurities can be a serious problem, and hence even cast alloy scrap direct from the foundry isn't usually recycled to make wrought alloys.

And I ran a tap in on one of your main mines, and it's all laced with impurities: vanadium and molybdenum.

But the humans who used that technique produced something called `wootz' steel that happened to have the very impurities the Doc here was talking about thanks to the local ores.

You might not get as pronounced a `water' pattern using steels without the impurities, but your people would still be turning out some of the best weapon-grade steel in the world!
