For enforcing the different applications on ceramics, various kind of special pigments are available. How much of which pigment will have to use depends upon the desire color intensity. But, the quantity of pigments that is used for these applications can vary from 1% to 10%. this variation does not make any noticeable impacts on the substances. Enamel (colorful) can be produced by coloring the melt during manufacturing. Enamel can be also generated by mixing coloring stains during the milling process.

Enamel (colorful) can be produced by coloring the melt during manufacturing. Enamel can be also generated by mixing coloring stains during the milling process.
To color ceramic products and glass products, heavy metal
oxides are either dissolved in the ionic coloration (melts) or can be
incorporated into the melt like pigments or pigmentation process can be
adopted. On several factors, the coloring effects of the pigments and stains
depend. These factors are: nature of the raw materials, the firing
temperature, dwell time and kiln atmosphere. For coloring the sanitary
ceramics, a number of inorganic pigments are required.
Cadmium, Tin-Oxide, Nickel-hydroxycarbonate, Ceramic
Glaze Pigments etc., are the some other important pigments that are used for
ceramics. Cadmium pigments provide a wide range of rich color to the
ceramics, like red, orange and yellow. Cadmium pigments are highly
resistance to heat and pressure and very less soluble. So, these pigments
are exposed to high temperature or pressure during the application process
to ceramics.
Tin oxide pigments are versatile materials for ceramics. The thermal stability and chemically inert nature of tin oxide enable it to generate a board palette of durable ceramic colors.

Cobalt as a pigment for ceramicsThe color imparting capacity of cobalt containing
minerals is very old. It has been utilizing as a pigment from the
ancient period. This property of cobalt has been used in glass,
ceramics, paints, inks, porcelain etc. But, as a pigment, cobalt is more
famous for ceramics. Some unique properties, those are present in
cobalt, have make it the most widely applicable pigment for ceramics.
These unique properties of cobalt are: solubility, stability, coloring
effects etc. |
