INTRODUCTION

The use of spray drying in ceramic manufacture began in the mid 1950's for whitewares, e.g. floor and wall tiles. There followed a growth in electronic ceramics (ferrites, titanates, nitrides) and hard metals (carbides).

In recent years we have seen the emergence of advanced ceramics for new and varied applications including heat engines, turbines, high capacity batteries even for artificial bones, joints and heart valves.

Many of these novel applications have stringent requirements not just in terms of particle form but also in terms of purity cross-contamination and containment more commonly associated with the pharmaceutical industry.

The aim of this Paper is to outline the development of the spray process to meet these new challenges.
