Abstract:
Clay materials useful as binding agents in green sandcasting and other molding processes are discussed, as well as methods of preparing such clay materials. The clay materials may be chemically treated. For example, a natural clay may be combined with one or more reducing agents, such that an amount of iron present as ferric iron (Fe3+) in the natural clay is at least partially reduced to ferrous iron (Fe2+) in the chemically-treated clay. The chemically-treated clay may exhibit greater water absorption, binding properties, and/or sintering properties as compared to an untreated, natural clay.

Abstract:
Procedure for controlling the chemical reaction in multi-layer ceramic decorations, according to interfacial and surface properties, in which the ceramic coating formulation is broken down into two separate compounds: on the one hand, a bottom layer formed by a glaze with part of the necessary oxides to obtain the ceramic effect, applied in the conventional manner over the ceramic substrate, and on the other hand, a top layer formed by an ink with the other necessary part of the oxides, applied by injection over the previous layer. The ceramic product is finished off with a firing process. This procedure has the advantage of regulating the penetration of the oxides of the top layer throughout the profile of the bottom layer, thus achieving an adequate concentration of oxides in the zone nearest to the surface, which permits optimization of the chemical reaction and thus, of the ceramic effect obtained.

Abstract:
The present invention relates to a novel process for producing ceramic materials, in particular refractory materials having a reduced relative density. In particular, the invention relates to a process for producing light, refractory materials having non-contiguous pores based on shaped and unshaped materials. These materials can be used as working lining in high-temperature applications. The process is based on the production of spherical, closed and isolated pores in the microstructure of the material. The pores having a pore diameter which can be set in a targeted manner are generated by use of polymer particles, in particular polymethacrylates, in particular polymers or copolymers prepared by means of suspension polymerization, as pore formers which can be burnt out. The polymers or copolymers are present in the form of small spheres having a defined diameter. The introduction of isolated spherical pores allows the production of ceramic materials having a sometimes significantly reduced relative density and improved corrosion resistance and better mechanical strength compared to the prior art. The specific, closed pore system at the same time contributes to reducing the thermal conductivity of the ceramic materials. In addition, the novel process has the advantage that there is no risk of formation of undesirable black cores, even in the production of thick-walled ceramic products.
