Inorganic pigments based on the structure of hibonite, its process of sufffdntese and their utilizau00c3u017des

摘要

This invenu00c3u2020o is related with an inorganic pigment blue, which is based on the structure of the hibonite, which consists of a hexaluminato calcium fu00cbrmula simplified caal12o19. The structure of the sufffdntese hibonite, with iu017des cromu00cbforos incorporated in the crystalline network (e.g.Ni), in reacu00c3u2020o of state su00cblido, replacing part of the catiu017des Al3 +, enables the obtenu00c3u2020o a pigment of dissoluu00c3u2020o su00cblida with adequate stability quufffdmica and thermal and capable of giving colour to a wide range of products, including ceramic products NEC Essitam to be processed at high temperatures.In this invenu00c3u2020o, sufffdntese this structure when combined with the structure of the anortite still allows a substantial reduu00c3u2020o of processing temperature. In addition, the concentrau00c3u2020o cromu00cbforas species is relatively low, which minimizes the final cost of the pigments.The process of sufffdntese used to obtenu00c3u2020o of said pigment consists of the following steps: dosing, and homogeneizau00c3u2020o of raw materials, calcinau00c3u2020o mixture, washing and milling. The present invention is primarily intended to be produced in the ind...Stria of colorifufffdcios, with aplicau00c3u2020o in the areas of decorau00c3u2020o, in particular in the ind...Stria ceramics.
