A method for post-processing a colored zirconium oxide ceramic, the method comprising: putting the colored zirconium oxide ceramic along with a deoxidant into a heating device, conducting a firing process at a preset temperature, and a colorant containing Pr.sup.3+ is used for the coloring, and the deoxidant is excessive with respect to a stoichiometric amount of oxygen in the heating device. The technical solution can completely replace Fe.sup.3+ with Pr.sup.3+ to color the zirconium oxide ceramic yellow.

A system, method and kit for coloring dental ceramics. The system, method, and kit resulting capable of adjusting the shade of a dental restoration milled from a colored zirconia porcelain block from one color value of the VITA shade guide to a different color value of the VITA shade guide.

The present invention relates to the use of fine ground calcium carbonate having a weight median particle diameter d50 of 0.5-5 m in combination with an inorganic pigment in concrete or mortar in order to improve the workability of the mixtures as well as the properties of the resulting cement-based products.

Cement, concrete, stucco, and plaster that are have black ceramic polymer derived pigment included as an encapsulated water soluble sacket added to the powered or wet materials. A ceramic black SiOC additive encapsulated in a water soluble sacket and having a particle size of about 0.1 m to 3 m.

A ceramic body is provided that is suitable for use in dental applications to provide a natural aesthetic appearance. A colorized ceramic body is formed that has at least one color region and a color gradient region. A ceramic body is formed having at least two color regions and a color gradient that forms a transition region between two color regions. A method for making the colorized ceramic body includes unidirectional infiltration of a coloring composition into the ceramic body.

The method for manufacturing a ceramic component, in particular component containing zirconia and/or alumina, for a timepiece or a jewelry piece, is characterised in that it includes a step (E3) of depositing at least one additional element or compound on a ceramic powder, optionally bound, by atomic layer deposition (ALD).

A tintable cement-based composition that includes a cement-based powder component and a pigment component. The powder component includes Portland cement, a filler, calcium sulfate hemihydrate, aluminum oxide, and Sepiolite clay; and the pigment component includes at least one pigment. The components can be packaged separately and mixed with water at the point of use.

The present invention relates to fiber cement flooring products. In particular, the present invention provides fiber cement flooring products, at least comprising cement and fibers, characterized in that these fiber cement flooring products comprise amorphous silica in an amount of between about 2 weight % and about 15 weight % compared to the total dry weight of the fiber cement composition of said fiber cement flooring product. The present invention further relates to methods for the production of such fiber cement flooring products as well as uses of such fiber cement flooring products in the building industry. The present invention further relates to fiber cement formulations and fiber cement materials, which are suitable for the production of fiber cement products for flooring applications.
