osmiridium's Usage Examples:

In this process the osmiridium is fused with zinc and the excess of zinc evaporated; the residue is then ignited with barium nitrate, extracted with water and boiled with nitric acid.

As an alternative the osmiridium is fused with zinc, the regulus treated with hydrochloric acid, and then heated with barium nitrate and barium peroxide.

It may be prepared from osmiridium by fusing the alloy with zinc, the zinc being afterwards removed by distillation.
