Examining Si3N4 Base Materials with Various Rare Earth Additions
Abstract
Silicon nitride base compositions were prepared by using various rare earth oxide additives and hot pressing the powders to full density. Compositions were primarily explored in Si3N4-SiO2-RE2Si2O7 compatibility regions although other Si3N4-RE2O3 reactions were also investigated. Hot pressing densification data and high temperature behavior of the various silicon nitride rare earth compositional systems are examined.
