ABSTRACT:
Green bodies suitable for use in manufacturing ceramic articles are provided. The bodies comprise a coherent mass of particles of titanium dioxide free of organic binder and having a fracture stress measured by a biaxial disc flexure test of at least 5 MPa. The particles of titanium dioxide are coated with at least one inorganic oxide or hydrous oxide.
The green body can be shaped by drilling, sawing etc. to a desired shape approximating to that of the ceramic article which it is used to produce. Generally such shaping is considerably easier than shaping the finished ceramic article.
