The blue jowl, the fat-lidded eyes now merry, now alert, now tungsten hard the bullet head, the pudgy fingers and the square-toed shoes were all in conformation with the doctor's olden mental picture. "Yes; I know I look it," said O'Higgins, amiably. The doctor laughed. But he sobered instantly as he recollected that O'Higgins had found Spurlock once.
So are tungsten for filaments, tantalum for plates, and platinum for leads; and I haven't found anything that I can use as a getter, either a metal, you know, to flash inside the tube to clean up the last traces of atmosphere in it."
"Tell 'em -that you don't know," finished Farley tantalizingly, and vanished. It was not until long after that Darrin found out the explanation of the accident to the tungsten bulb. Farley, during Dan's absence, had been almost as much disturbed as had Dave. So Mr. Farley was wide awake. When he heard Lieutenant Adams receive the message in the corridor Farley began to wonder what he could do.
"This is Terra base. Go ahead, Foster. How are you doing?" "If you need anything cooked, send it to us," Rip replied. "We have heat enough to cook anything, including tungsten alloy." He explained briefly what action they had taken. A new voice came on the communicator. "Foster, this is Colonel Stevens." Rip responded swiftly, "Yes, sir!"
The ninth successive experiment on the release of atomic energy had failed. The tenth was in process of construction. A heavy pure tungsten dome, three feet in diameter, three inches thick, was being lowered over a clear insulum dome, a foot smaller. Inside, the real apparatus was arranged around the little pool of mercury.
Blount was fully informed now of the terms of his contract and of the source of his sudden wealth, but there was no way of reaching the buyer. A great war was on, every minute was precious and every ounce of the tungsten was needed. The munitions makers could not pause for a single day in their mad rush to fill their contracts.
It comes in pretty handy to harden those big guns that you hear shooting over in France." "Oh, tungsten," muttered Charley, blinking wisely at the rock while everyone else grabbed a sample. "Er what do you say they use it for?" "Why, to harden high-speed steel for guns and turning-tools haven't you read all about it in the papers?"
To begin with metals, uranium melts at 1150° centigrade, and tungsten at 3370° and irridium at 2350°. You could load such things and melt them down in space and then tow them home. And you can actually sterilize a lot of other useful materials!" The suave voice was infuriated: "I'll report this! You'll suffer for this!"
Neutrons aren't used in any process I've run across." "Well, remember they're uncharged, tiny things. Small as protons, but without electric field. The result is they pass right through an ordinary atom without being stopped unless they make a direct hit. Tungsten, while it has a beautifully high melting point, is mostly open space, and a neutron just sails right through it, or any heavy atom.
These are platinum, gold, tungsten, mercury, lead, palladium, silver, bismuth, uranium, vanadium, copper, cadmium, cobalt, arsenic, nickel, iron, molybdenum, tin, zinc, antimony, tellurium, manganese, tatiaum, chromium, columbium, rhodium, iridium, osmium, cerium. Many of these, however, are so rare, that as yet they are of no practical use.
