Rare earth and yttrium metals are readily available from our in ventory in a wide range of purities in experimental quantities. Primary forms are ingots, lumps and turn ings. Costs are reasonable and ad vantageous for your research or product development operations. Lindsay rare earths cover the whole gamut of rare earth tech nology, from crudes to highly re fined materials. One of the signif icant properties of the rare earth metals is their scavenging ability for oxygen, sulfur, and some other non-metallics. LOOK AT YTTRIUM, TOO Yttrium shouldn't be overlooked either. It is available in grades ranging from high purity to crude alloys with magnesium. Lindsay has been working with the rare earths for nearly 60 years, and is the world's largest pro ducer of rare earth, yttrium, and thorium materials. We can furnish you with a considerable amount of interesting and revealing tech nical data on rare earth and yt trium metals, including a detailed tabulation of properties, purities, and costs. Please ask for our bulletin "Rare Earth and Yttrium Metals." It will be sent to you promptly.

VISCOSITY and BROOKFIELD can profit you! It's true. In-process viscosity measurement is the most direct progress report of many chemical reactions that you can obtain. In polymerization reactions, for example, Brookfield process-mounted Viscometran units eliminate the need for constant sampling, assure greater product uniformity and guard against run-away reactions. Like color, pH and stability the viscosity of any material is a vital property, a fundamental measurement, which can be easily and accurately evaluated and controlled with low-investment Brookfield instrumentation. If you would like to know more about the profitable role of viscosity control in your processes, write today for complete technical information. There is no obligation.
