Silicon Nitride Ceramics with Sintering Oxide Additives Obtained from Organoyttriumoxanealumoxane
Source abstract
Abstract
Sintered blanks for spherical bodies of rolling from silicon nitride ceramics were obtained using the addition of an yttrium-containing organoalumoxane ― element organic oligomer, soluble in traditional organic solvents and rolling in pyrolysis into an oxide aluminum-sintering additive in a given mass ratio Al2O3/Y2O3 = 3/1. Studies conducted using thermogravimetry, X-ray phase analysis, optical and electron scanning microscopy showed that the feature of the use of elementoxane instead of the sintering additives of aluminum and yttrium oxides powder is a uniform distribution of aluminum and yttrium oxides in Si3N4- ceramics and the chemical activity of pyrolysis products of organoyttriumoxanealumoxane (OYA), Including amorphous nanoscale oxides on the surface of the Si3N4 powder. Density, porosity, microstructure and the degree of purity of the polished surface of the obtained ceramics indicate its prospects for use as a blank of high-quality rolling bodies. Ill. 6. Ref. 16.
