CeZnGe crystallizes with the hexagonal YPtAs-type structure, space group P63/mmc, a = 430.0(2), c = 1678.8(10) pm. A phase-pure sample was synthesized from the elements in a sealed tantalum crucible in a high-frequency furnace. Magnetic susceptibility measurements have revealed a trivalent cerium with an experimental magnetic moment of 2.67(1) μB/Ce atom. Ferromagnetic ordering sets in at TC = ...

In an article about the importance of choice materilas, harmful impurities in synthetic cast iron, amd improving strength characteristics which requires a new method smelting iron using steel scrap as charge corrresponding crucible furnaces, presences metal charge, together with pig return own production, carburetors, and ferroalloys for purpose carburizing alloying to required chemical composi...

In this study, degradation by so-called “Obake” , an advanced stage of external corundum growth on alumina-silica refractory surfaces, was investigated. The Obake successfully recreated melting Al-5%Mg in the crucible under thermal cycle conditions. test temperatures were chosen at 1000°C or 1150°C. It confirmed that internal occurred formation spinel (MgAl2O4) where touch with molten Al-5Mg an...

National Institute of Standards and Technology, Gaithersburg, MD 20899-0001 Blackbody sources with nearly unity emittance that are in equilibrium with a pure freezing metal such as gold, silver, or copper are used as primary standard sources in the International Temperature Scale of 1990 (ITS-90). Recently, a facility using radio-frequency induction heating for melting and filling the blackbody...

The sleuth-like style and lucid writing certainly make this book an enjoyable read. Many explanations are framed by relevant historical context and tales of mathematicians whose use of experimental mathematics helped them gain insights into difficult problems. Although it was never intended to be a course textbook, it could be used as a supplementary text. Many of the chapters are short, and sh...
