The technique for measuring o J the thermoelectric effect in supercomhtctors near the critical temperature T c has been ehtborated. The measured magnetic Jlux was imhtced by temperature gradient (AT ~ 1 K) between joints. The experhnental study of the thermoelectric eJfect has been carried out in the hollow bimetallic superconducting cylinder consisting oJ" the Pb and Pb-ln alloy. The observed temperature dependence of the thermoexcited magnetic flux has been well approximated by the logarithmical Jimction. The magnitude order of the thermopower estimated J?om the experbnental &tta coincides with the known low temperature thermopowers of metals.
For various materials, rapid generation of results is always critical. Particle-size analysis of processing products using a laser-based particle-size analyzer is a valid alternative to the traditional sizing test. The article presents the results of studies conducted using Microsizer 201C equipment by the example of layered aluminosilicates and metal powders for additive manufacturing. The size analysis for these products is generally complicated by their ability to stick and agglomerate. Ultrasonic mixing does not harm the material analyzed and promotes uniform distribution of the sample during analysis. The results of granulometric analysis of kaolin ores obtained after different heat treatment are presented. The results of air-electric classification of metal powders obtained after vibration disintegration of metal chips are presented. The variety of raw materials shows a wide range of applications of this method in industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
