Introduction The advanced ceramic powders such as aluminum oxides and hydroxides generally require chemical conversion of raw materials into intermediate compounds, which lend themselves to purification and subsequent chemical conversion into the final desired form.In general ceramic materials undergo reconstructive transformation.
For the fabrication process it is necessary to convert the ceramic powder to the stable form before consolidation because low densities are usually obtained on sintering if the powder undergoes transformation during heating [1].
