Obtaining and Characterizing Phosphatic Porcelain

Résumé

The research aimed to obtain phosphate porcelain, by using the ash resulting from burning bones from meat processing plants. The applied processing technology allows obtaining fine ceramics at lower temperatures than the one used in the case of feldspar porcelain, having as effect the increase of the durability of the firing furnaces and the realization of the products at lower production costs. Five series of phosphate porcelain samples were performed in laboratory conditions, with different compositions, by firing at a temperature of 1250 ℃, temperatures lower than those necessary for the firing of feldspar porcelain of 1350-1450 ℃. The porosity and density of the samples were determined and the microstructural analysis of the materials made in the five research variants was made.
