INDUSTRIAL CERAMIC PIGMENTS
Ferro's specialty industrial ceramic pigments are designed to color all types of special glazes and bodies used for industrial ceramics. Our ceramic pigment range contains 25 ceramic stains that exhibit high purity, intensity and brilliance.
Ferro's industrial ceramic pigments are designed to color all types of special glazes and bodies used for industrial ceramics. Our InstantColor® ceramic pigment stains offer 25 shades that result in an infinite number of colors that exhibit high purity, intensity, and brilliance within the complete color spectrum. Significant cost savings can be achieved as colors are easily adjusted right in the barrel.
Our ceramic inclusion pigments create shining red, brilliant orange, and intense yellow color shades of ceramic bodies and glazes at high firing temperatures. This adds much more versatility to the traditional spectrum of colors available to the ceramic world. The chemical and thermal stability of our inclusion pigments also ensures both a high level of production safety and excellent end-product profitability.
A significant environmental advantage of our cadmium-based inclusion pigments is the low amount of cadmium that is able to achieve the desired brilliant color at high firing temperatures. These pigments are stabilized by encapsulation in chemically and thermally stable crystals.
Proven Quality
All the ceramic stains in our InstantColor® range consist of extremely fine, uniformly minute particles that are dissolved instantly. These colors are readily dispersed in standard slurries, requiring no ball milling, as practically all primary grains are smaller than 32 μm with no coarse agglomerates that need grinding for slurry preparation.
FERRO INSTACOLOR®ADVANTAGES
Optimum Glaze Compatibility
Even in opaque glazes, InstantColor® stains create uniform, defect-free surfaces in both fast-firing and traditional firing conditions.
Extremely Fine and Uniform Particles
Easier dispersibility, no ball mills, less production time, and less waste. InstantColor® stains can also be prepared using a traditional ball mill.
Cost Effectiveness
InstaColor® ceramic stains are designed to significantly reduce production through the combined use of slurry preparation and fast-firing. By eliminating ball milling there is minimal waste, reduced capital investment, decreased cleanup time, and less disposal water.
Environmental Compatibility
Our lead-free* stains (with the exception of some sphenes) are particularly suitable for lead-free glazes.
Stains using cadmium to achieve brilliant reds and oranges encapsulate the color crystals in zirconium silicate, creating inert inclusion pigments.
Enables Flexible Production
Without the need for ball mills, small batches can be easily prepared, and colors can be switched from to another quickly, enabling just-in-time production.
