GEL CASTING METHOD FOR COMPLEX-SHAPED DENSE CERAMIC FABRICATION

Characterization of Novel Gel-Casting System to Make Complex-Shaped Aluminum Oxide (Al2O3) Parts

Fabrication and study of color and physical properties for cobalt silicate-titanite ceramic pigment by sol-gel method

Cobalt-based blue ceramic pigments are widely used in ceramic industries due to characteristics such as temperature stability, chemical stability and high resistance to these coatings. In this research, the blue silicate - titanate cobalt ceramic pigment is synthesized by sol-gel method and the dispersed pigments were printed on the ceramic by silk screen printing method in the industrial produ...

The production of Ceramic Thin Films by Sol-Gel Method

The purpose of this work was to production of ceramic thin films by using of Sol-Gel process. For this purpose deposition of SiO2 on substrates of soda-lime glasses has been carried out. Coating treatments on prepared specimen were conducted in a Sol solution by means of dipping at various times. After drying and performing appropriate heat treatment on each sample, the thickness of coated laye...

Fabrication of high–strength alumina composite foams through gel–casting process

A water–soluble gelatin combined with polyethylene microspheres were developed to prepare alumina composite foam. Gelatin was used as the gelling agent and polyethylene was used as pore making template. On the other hand, kaolin was used to provide green strength and CuO was applied to decrease the required temperature as a sinter aid. Alumina bodies need elevate temperature for sintering, incr...
