Scientists of the National Research Nuclear University of Russia, together with colleagues from Moscow State University of Geodesy and Cartography, Institute of Structural Macrokinetics and Materials Science, Russian Academy of Sciences and the Institute of Metallurgy and Materials Science n.a. Baikov have developed a technology to produce compacts from aluminum oxynitride.
To obtain “transparent aluminum”, the researchers from have applied a method of spark-plasma sintering.
“Spark-plasma sintering is a new sintering process, which is based on the modified method of hot pressing. In this case, electric current goes directly through a press mold and pressed billet, but not through an external heater. With the help of a pulsed current, a very rapid heating is achieved for an extremely short cycle time”, the document reads.
