## Abstract Flowerlike structured In~2~O~3~ were successfully synthesized via a hydrothermal process and the subsequent calcinations. The obtained sample consists of microrods with an average diameter of 0.5β1 ΞΌm and a length of 1β3 ΞΌm. Structure and property of the sample were characterized by Xβr

## Abstract Yb:Y~2~O~3~ submicrometric particles were synthesized through coβprecipitation of Yb and Y nitrate in water. Microwave heating and controlled release of ammonia through urea decomposition at reaction temperature leaded to the formation of disaggregated, monosized spherical particles of
The mechanical alloying process of (ZrO 2 ) 0.8 +( -Fe 2 O 3 ) 0.2 powder during high-energy ball milling at room temperature and the thermal decomposition of (ZrO 2 ) 0.8 +( -Fe 2 O 3 ) 0.2 powder at high temperature were studied by XRD, TEM, and di4erential thermal analysis. It was found that mono
