But there can be sterilization. To begin with metals, uranium melts at 1150° centigrade, and tungsten at 3370° and iridium 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 said infuriatedly; "I'll report this! You'll suffer for this!" Calhoun said pleasantly;
Mushet's failure to make the public appreciate his theories has not injured his inventive faculties." These patents include, besides variations on his "triple compound" theme, his important patent on the use of tungsten for cutting tools, later to be known as Mushet steel. Mining Journal, 1859, vol. 29, p. 539 and 640.
True, the loudspeaker, the microphone, and all other instruments made of ordinary matter had been burned off clean. They didn't even have to clean out the spaces where they had been recessed into the wall. At a temperature of ten thousand degrees, the metals had all boiled away even tungsten boils at seven thousand degrees, and all other normal matter boils even more easily.
So firmly convinced had Adams been that Dan was about to make a denial that now, with the incident broken in two by the report of the tungsten bulb, Lieutenant Adams really believed that had so denied. But Dan had not, and had Dave Darrin been called as a witness he would been compelled to testify that Dan did not deny being out.
During the last four or five years lamps with filaments made from tantalum and tungsten have been produced and placed on the market with great success, and are now largely used.
The metal in it was silvery, liquid, and here and there a floating crystal of the dull red metal. Slowly a smile spread across his face. He turned to Douglass. "Douglass ah, you're through. Get on the trail of MacBride, and get him and his crew to work making half a dozen smaller things like this. Tell 'em they can leave off the tungsten shield. I want different metals in the receiver of each.
From watching that man's torch, from the color of the flame and other indications, I gather that he uses a flame of atomic oxygen-atomic hydrogen for melting, and surrounds it with a preheating jacket of atomic hydrogen. The center flame probably develops a temperature of some 4000° centigrade, and will naturally make that tungsten alloy run like water.
He carried, as Tom could see, a large-sized electric flash-lamp, with a brilliant tungsten filament, which gave a powerful light. As the youth watched, he saw the intruder place the light on a bench, in such a position that the rays fell full upon the Humming-Bird.
They could prospect the ground later. Tungsten now was king. Men who had never heard the name, or pronounced it haltingly, now spoke learnedly of tungsten tests; and he was a poor prospector indeed who lacked his bottle of hydrochloric acid and his test-tubes and strip of shiny tin.
The Germans, it seems, have made a forty-two centimeter gun that is blasting down cities in France; and the Allies, to beat them, are constructing still larger ones made out of tungsten that is mined from the Paymaster. Yes, yes, Charley, that's all right, I don't doubt your word, but we'll call on Wiley for the details."
