Pure molybdenum is sensitive to oxygen at the temperature it

takes to melt it . . . and "moly" with oxygen is not much use. Jet en­gines, rockets, and other equipment need the pure metal because it stands up under heat that melts the strong­est steels, but if there's oxygen in it the advantage vanishes.

High vacuum solves the problem. Climax Molybdenum Company of Det ro i t , Michigan, hydraulically compresses pure molybdenum powder and sometimes molybdenum chips with a little carbon. This mass is sintered into a crude stick which serves as a consumable electrode in an arc. The molten metal is caught in a pool which serves as the other elec­trode while it builds up into a half-ton ingot of malleable, ductile

high vacuum r

molybdenum. The molybdenum turns out malle­

able and ductile because high vacuum gets rid of the injurious oxygen.

Why, you may ask, don't they just use an inert gas? Bear in mind that at the high vacuum under which these operations are carried out (20 microns Hg) oxygen content is equivalent to about 0.0026% at atmospheric pres­sure. Inert gas pure enough and in sufficient quantity to dilute atmos­pheric oxygen to this level would be staggering in cost. A DPi oil ejector pump, uniquely economical to oper­ate, creates the vacuum in the sizable space needed for the whole series of continuous operations and gets rid of the gases evolved.

In supplying equipment for high vacuum metallurgy, DPi pools its

search and engineering

own diversified experience in high vacuum technology with the experi­ence of leading manufacturers of metallurgical furnaces.

In many other fields, too, where high vacuum processing has earned a useful role, DPi stands ready to help you with the vital details that add up to efficient, profitable production.

After extensive laboratory and field tests, Oronite proudly introduces two outstanding nonionic detergents—Dispersant Nl-W (water soluble) and Dispersant ΝΙΟ (oilsoluble). Oronite offers both products in uniform quality, at stable prices and in assured supply.

Dispersant Nl-W (FORMERLY NI 8586)

Oroni te ' s new Dispersant N I - W is a clear, light straw-colored l iqu id—95% active. It may be compounded with phosphate or other builders and dried to give free-flowing granular products. It is also suitable for the making of liquid detergents. You will find N I - W very adaptable for the manufacture of economical, h igh-qual i ty formulat ions. It is completely compat ible with soaps and anionic detergents. As shown by the chart, unusual cot ton detergency may be obtained. This new Oroni te product is particularly suitable for manufacturing detergents for commercial or self-service laundries and automatic home washers. Technical bullet in describing Dispersant N I - W is available on request.

Dispersant ΝΙΟ (FORMERLY NI 8593)

This new clear, straw-colored liquid detergent is an excellent emulsifier for water-in-oil emulsions. Dispersan t N I - O was specially designed for use as a dry cleaning detergent in systems employing all types of solvents. It has the ability to suspend large quantities of finely divided solids in solvent media. It ex­

hibits superior detergency and is not readily absorbed by filter aids.Technical bulletin is avail­able on request.
