A factorial design experiment was conducted to determine the major parameters affecting the densification of mixtures having the composition (in mol%) 50 Si3N4, 25 A12O3, and 25 A1N. Improved densities of the resulting sialon were achieved using a lo

Examination of compositions in the system Si3N4-Y2O3-SiO2 using sintered samples revealed the existence of two regions of melting and three silicon yttrium oxynitride phases. The regions of melting occur at ∼1600° C at high SiO2 concentrations (

A new group of materials called the silicon lanthanide oxynitrides has been prepared by the reaction between Si3N4 and several oxides of the lanthanide series (La2O3, Sm2O3, Dy2O3, Er2O3, and Yb2O3). These oxides formed compounds of the type Si3N4 ·

Controlled surface flaws were produced in commercial reaction-densified SiC by Knoop microhardness indentation. The flaws themselves could not be observed easily, thus an etching technique was used to delineate their semielliptical shape, thereby ena

The oxidation-reduction kinetics of MnO in CO/CO2 atmospheres at 1230°C were measured by gravimetric and electrical conductivity techniques. The dependence of the kinetics on time, inert gas dilution, total pressure, and specimen thickness indicates
