fairly expensive and, with the onset of World War II, difficult to obtain in the United States. In the 1930s employees of the American Chemical Paint Company developed the zinc phosphate process. This process was more energy efficient than manganese, and became the primary process used on American war materials during World War II.

Zirconium

Zirconium oxide is used to make heat resistant crucibles, ceramics and abrasives. A red-hot crucible made from it can be plunged into cold water without cracking. Zirconium oxide is to be found in ultra-strong ceramics that are stronger and sharper even than toughened steel and are used for knives, scissors and golf irons.
