Zn-Co-Al Cobalt Blue Ceramic Roller Printing Stain

FULLN CHEMICAL Zn-Co-Al Cobalt Blue Ceramic Roller Printing Stain (Cobalt aluminum blue) FU-534R is a kind of inorganic ceramic pigment blue color composed of zinc oxide, cobalt oxide, alumina and other raw materials by mixing, calcining and micro powder processing. This series of blue is suitable for ceramic rotor printing.In the process of high temperature calcination, zinc oxide, cobalt oxide, alumina disperse in the form of ion diffusion according to the different proportion, then form spinel crystal structure. Its composition may contain one or several group of boric acid, halide. It's suitable for oxidizing atmosphere firing. This series of ceramic roller printing pigment Cobalt Blue are suitable for various of glazes.

Zn-Co-Al Cobalt Blue FU-534R is a high-temperature inorganic ceramic printing pigment based on zinc-cobalt-aluminum composite spinel crystal structure. Through the characteristic color development of Co²⁺ ions in the spinel lattice, it presents a bright and vivid blue tone. Specially designed for ceramic roller printing decoration, this product features pure color, strong tinting strength, excellent transferability, and high print clarity. It is widely used for roller printing decoration on ceramic tiles, mosaics, and other building materials.

Co²⁺ ions occupy tetrahedral or octahedral coordination positions in the spinel structure. Under ligand field effects, their 3d electrons undergo d-d transitions, generating characteristic bright blue absorption spectra. Zn²⁺ and Al³⁺ serve as lattice stabilizers, effectively regulating crystal field strength to ensure vivid and pure color development while enhancing high-temperature stability and chemical inertness. After printing and high-temperature firing, the pigment fuses with the glaze layer to form a durable and stable blue decorative effect.

FULLN CHEMICAL ceramic roller printing pigment Cobalt Blue series is dedicated to the roller printing products. According to the characteristics of the roller printing process, the fineness of the rotor color products is required to be over 400 mesh and the moisture content is less than 0.5%. The color categories of this series of products cover all the current ceramic decoration colors, but also matched according to the customer's requirements. In the usage of rotor colors and printing powder, printing oil is mixed evenly in proportion. FULLN ceramic roller printing pigment Cobalt Blue products can get through 325 mesh screen. Our ceramic roller printing color can be used in ceramic products such as archaize brick, porcelain, all - cast glaze, microspar, etc.
