It had a mottled, pinkish shine, partly from untarnished lead, osmium, considerable uranium, some iron, nickel, silver, copper. The metals were alloyed, here; almost pure, there. There was even a little rock. But thirty-five percent of Pallas' roughly spherical mass was said to be gold.
A device for sealing together the inside part and bulb of an incandescent lamp mechanically. Regulators for dynamos and motors. Three devices for utilizing vibrations beyond the ultra violet. A great variety of methods for coating incandescent lamp filaments with silicon, titanium, chromium, osmium, boron, etc. Several methods of making porous filaments.
We have the names in one of the tables arranged in two columns, representing, as you see, two groups platinum, iridium, and osmium constituting one group; and ruthenium, rhodium, and palladium the other. Three of these have the chemical equivalent of 98-1/2, and the others a chemical equivalent of about half that number.
Then the metals of one group have an extreme specific gravity platinum being, in fact, the lightest of the three, or as light as the lightest. Osmium has a specific gravity of 21.4, and is the heaviest body in nature; platinum is 21.15, and iridium the same; the specific gravity of the other three being only about half that, namely, 11.3, 12.1, and 11.8.
Frank Nelsen meant the journey to be vagabond escape, an interlude of to hell with it relief from the grind, and from the increasingly uncertain mainstream of the things he knew best. He rode with a long train of bubbs and great sheaves of smelted metal rods tungsten, osmium, uranium 238. The sheaves had their own propelling ionic motors. He lazed like a tramp.
And right now, sir it's probably as expensive for them to refine iron as it is for us to handle titanium and beryllium and osmium which are duck soup for them! Our two cultures ought to thrive as long as we're friends, sir. They know it already and we'll find it out in a hurry!" The skipper's mouth moved. It closed, and then dropped open again.
Upon this shelf a bit of the alloy of two exceedingly hard metals, iridium and osmium, is secured by melting the gold around it; and it is this bit which stands all the wear of rubbing on the paper. When gold pens were first made, tiny bits of diamonds or rubies were soldered on for points; but they were expensive, and they had a disagreeable fashion of falling off.
From their previous remarks it was clear that the asteroids, those fragments of an exploded and once populated world, orbiting out beyond Mars, would be for them. Osmium, iridium, uranium. The rich, metallic guts of a planet exposed for easy mining. Thousands of prospectors, hopeful characters, and men brutalized by the life in space, were already drifting around in the Asteroid Belt.
So it's almost worthless, everywhere. Not much use as an industrial metal. But the osmium and uranium alloyed with it are something else. One hunk for each of our nets. Too bad there isn't more." The uranium was driving their radiation-counters wild. "Could we drag it, if there was more?" Ramos growled. "With just sun-power on these lousy shoulder-ionics?" Everything was going sour, even Ramos.
This substance is always native it is always in the metallic state; and the metals with which it is found connected, and which are rarely found elsewhere, are palladium, rhodium, iridium, osmium, and ruthenium.
