Abstract
A laboratory-scale facility for pyrolytic preparation of powders used in ceramic materials fabrication is presented. It is shown through examples that application of the technique described allows very homogeneous powders to be prepared which, by conventional techniques, can be prepared either with great difficulty or practically not at all. A typical application in the system ZrO2-Y2O3-Al2O3 is shown. From experimental results it is further demonstrated that suspensions can also be profitably processed. Dependent on the system used, the product fabricated is either crystallized or amorphous.
