SPARK-PLASMA SINTERING OF HIGH-STRENGTH COM¬POUNDS ON THE CORUNDUM POWDER SURFACE
https://doi.org/10.17073/1683-4518-2015-1-35-38
Abstract
By means of spark-plasma sintering the high-strength sub-stances boron suboxide and boroaluminate were obtained. The boroaluminate is a glassy substance which is not studied sufficiently. This substance forms as a result of the reaction between compacted sintered Al2O3 powder and the coating consisting of B and В2О3 powder mixtures. The data are given on both the micro-hardness and chemical analysis taken at different points of agglomerated samples. Ill. 6. Ref. 3.
