Effect of Y<sub>2</sub>O<sub>3</sub> addition on the properties of mullite bonded porous SiC ceramics prepared by an infiltration technique
Mullite bonded porous SiC ceramics were synthesized by infiltrating a powder compact of SiC and Y2O3 with a liquid precursor of mullite which on subsequent heat treatment at 1300-1500 ºC produced mullite bonded porous SiC ceramics. The effect of Y2O3 content and sintering temperature on phase compos...

| description | Mullite bonded porous SiC ceramics were synthesized by infiltrating a powder compact of SiC and Y2O3 with a liquid precursor of mullite which on subsequent heat treatment at 1300-1500 ºC produced mullite bonded porous SiC ceramics. The effect of Y2O3 content and sintering temperature on phase composition, microstructure, oxidation degree of SiC, flexural strength, porosity and pore size distribution were studied. Due to enhance oxidation and well developed neck formation by the addition of Y<sub>2</sub>O<sub>3</sub> a high strength 49 MPa was achieved for the porous mullite bonded SiC ceramics with porosity 28 vol %.<br><br>Se han sintetizado materiales porosos de SiC-Mullita mediante la infiltración de polvo prensado de SiC y Y<sub>2</sub>O<sub>3</sub> con un precursor líquido de mullita, el cual con un tratamiento térmico posterior a 1300-1500 °C da lugar a los materiales porosos de SiC-Mullita. Se estudió el efecto del contenido de Y<sub>2</sub>O<sub>3</sub> y la temperatura de sinterización en la constitución mineralógica, en la microestructura, en el grado de oxidación del SiC, la resistencia a la flexión, la porosidad total y su distribución de tamaño. Debido a la oxidación y a la mejora en la formación de los cuellos por la adición de Y<sub>2</sub>O<sub>3</sub>, se alcanzan altos valores de resistencia, 49 MPa, para estos materiales porosos de SiC-Mullita con porosidad 28 % en volumen. |
