摘要：

In this work aqueous ceramic suspensions were prepared from a parent glass-ceramic powder (3.8 mu m) belonging to the LZSA (Li2O-ZrO2-SiO2-Al2O3) system without or with additions of different volume fractions (1.0-7.5%) of TiO2 nanoparticles (25 nm). The obtained suspensions were rheologically characterized so that stable suspensions were defined e formed by slip casting. The obtained compacts were sintered (850-950 degrees C/60 min) and their green and sintered densities were determined and related to linear shrinkage measurements. The results showed that samples sintered at 950 degrees C for 60 min with 1.0% TiO2 addicted presented linear shrinkage of 12% and relative densities of 97%.
