Composition Of Ceramic Frits

A novel frit glass composition is disclosed which is particularly useful to apply color coatings to the soda lime glass envelopes of incandescent lamps.

Composition of ceramic frits.

Introduction in the manufacture of ceramic tiles ceramic glazes ap. Most simply it s a ground glass. Our base frits for screen printing powders and for ceramic coatings are specifically designed to enhance the chromatic range of digital printing inks. However it s a glass of a special composition typically high in flux elements low in alumina usually with enough silica to make a stable glass and sometimes containing boron.

Frit solubility glass ceramics kinetics glazes chemical durability i. The physical properties of the glassy phase summarized in table 7 vary according to the chemical composition of glass ceramic frits. When we speak about frits and glazes we have to consider that a glaze even when composed of only one frit is in contact with a ceramic body. Specifically the present glass frit can be combined with various inorganic coloring pigments to produce a colored coating when fired on the surface of the lamp glass envelope.

What is a frit. Frits are the main component of nearly all ceramic glazes and are present in many compositions of different materials where a glass face is needed even if only as a binder. However not all glass that is fused and quenched in water is frit as. Composition of the frits.

The purpose of this pre fusion is to render any soluble and or toxic components insoluble by causing them to combine with silica and other added oxides. The surface tension of liquid phase indicating its wetting capacity is raised by the glass ceramic frit additions whereas viscosity is generally decreased. This process known as fritting was developed to render any soluble and or toxic components insoluble and or nontoxic.

The multiple applications and various baking methods of the products which are used under different names have made it so that over the years the frits family has gained numerous members many of them very different. The glass frit is a composition expressed in terms of weight. Ferro offers a wide variety of specialty ceramic frits that include frits for engobes and compound glazes and frits for all different ceramic tile bodies and firing technologies. Ceramic frits frit is a ceramic composition formed by fusing inorganic materials into a glass by heating them in smelters and quenching them in water.

This proximity implies that the glaze composition will change because there is a migration of elements from body to glaze and vice versa.
