Abstracts

EN

Al_2(WO_4)_3 nanoparticles with average particles size of 20, 90 and 200 nm are sintered by two methods: cold pressing with additional sintering at different temperatures and time durations and hot pressure sintering. Density, particles size dimensions and anisometricity are tested. The results show that optimal initial nanosized dimensions and an optimal pressing condition are needed to obtain compact ceramic. Hot pressure method gives possibilities of a ceramic with a density in order of 99.8% to be received, which possesses some level of transparency.
