Abstract:
A method for producing thick ceramic films of greater than 10 .mu.m on selected substrates is described. Conventional sol gel solutions are loaded with up to about 90% by weight of finely divided ceramic particles and mixed. The resulting slurry or paint can be either spun or dip coated or sprayed or painted onto a planar or other substrate, fired to remove the organic materials and to develop a microcrystalline structure. The fired film may then be heated. Composite films are also contemplated.

Abstract:
An ink jet printing process includes jetting an ink composition onto a substrate. The ink composition is an emulsion or suspension of an organic phase in a water phase, the organic phase including at least one of oil and wax.
Abstract:
In a process for preparing a photoconductive pigment having a small particle size, a polymorph of a pigment is produced by a conversion process wherein a seed amount of the desired polymorph of the pigment and a larger amount of another polymorph of the pigment are subjected to a liquid jet interaction process.
