| 1. | Only gold, silver, copper and the platinum metals occur in nature in larger amounts.
|
| 2. | Ignition ( strong heating ) converts it to platinum metal:
|
| 3. | The Pt-Pt distance in Krogmann's salt is only 0.1 angstroms longer than in platinum metal.
|
| 4. | The platinum metals have many useful catalytic properties.
|
| 5. | Every such missile has gold, silver, platinum metals.
|
| 6. | Gibbs's research was mainly in analytical and inorganic chemistry, especially the cobalt-amines, platinum metals, and complex acids.
|
| 7. | Norilsk Nickel, the world's second-largest nickel producer and a major producer of platinum metals, rose to $ 9.48 from $ 8.21.
|
| 8. | A separate plate is then made with a thin layer of the iodide electrolyte spread over a conductive sheet, typically platinum metal.
|
| 9. | Ruthenium, like the other platinum group metals, is obtained commercially as a by-product from nickel, and copper, and platinum metals ore processing.
|
| 10. | As the platinum metal precursor is reduced to neutral platinum metal ( Pt 0 ), the reaction mixture becomes coalescence of the nanoparticles.
