Abstract
Shaped ceramic articles can be obtained by screen printing the desired shapes from a dimensionally stable dispersion of a precursor of the ceramic onto a surface, drying the screen printed shapes so obtained and firing them to generate the shaped ceramic articles.
Claims11
A process for the production of shaped ceramic articles by a screen printing process which comprises applying a dimensionally stable dispersion of a ceramic precursor to a receiving surface through a screen comprising a plurality of apertures, removing the screen from the support surface and then drying and firing the screen-printed shapes remaining on the support surface to form sintered shaped ceramic articles.
A process for the production of shaped alumina ceramic abrasive particles which comprises screen printing shapes of a dimensionally stable boehmite alumina gel onto a support surface, drying and then firing the shapes at a temperature sufficient to convert the alumina to the alpha phase.
