MUTUAL LINKAGE OF PARTICLES IN CERAMIC GREEN BODIES THROUGH REACTIVE ORGANIC BINDERS

Abstract

Because the pyrolysis of organic substances can result in the emission of carbon dioxide or other hydrocarbon gases, a reduction in the use of organic binders is one aim of current ceramics industry. A novel ceramic-forming process was developed that requires considerably less organic binder than conventional techniques. The process involves immobilizing reactive molecules on the surfaces of the ceramic particles, which on subsequent irradiation with electromagnetic waves, form bridges that bind the entire particle assembly together. The. chemical forces involved produce strong bonds, resulting in a significant reduction in the amount of organic binder that is required to maintain the shape of the ceramic green body. This method will help to decrease emission gases produced from pyrolysis of the binder.
