Composition for advanced hybrid geopolymeric functional materials and a process for the preparation thereof

Номер: US20140026787A1

The present invention provides a composition for advanced hybrid geopolymeric functional materials possessing very broad application spectrum ranging from cementitious materials to advanced functional materials having “Inorganic-Organic Hybrid” matrix in contrast to the limited application of conventional geopolymeric materials having “Inorganic matrix” only. The invention further relates to a process for the preparation of these materials. The process obviates the need of external addition of sodium silicate which is one of the costliest and main raw materials in conventional geopolymerisation processes. Interestingly, in the present invention the sodium silicate has been synthesized in situ by designing of conditions for synergistic and simultaneous mechano-chemical reactions among the selected raw materials viz. inorganic and organic wastes under alkaline environment. This results in the formation of “Hybrid inorganic-organic frame work” of sodium silicate, which facilitates uniform dispersion of reacting species, thus resulting in the formation of homogeneous geopolymeric matrix with improved characteristics.

METHOD FOR PRODUCING LIGHT CERAMIC MATERIALS

Номер: US20160176765A1
Принадлежит: Evonik Roehm GmbH

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. 1: A process for producing a ceramic material , comprising admixing a ceramic raw composition with from 0.5 to 90% by weight of spherical polymer particles having a diameter in the range from 5 μm to 3 mm , based on the sum of ceramic raw composition and spherical polymer particles , to obtain a mixture , optionally drying the mixture , and optionally thermally treating the mixture , wherein{'sub': 2', '3', '2', '2', '3', '2', '2', '2', '3', '2', '2', '3', '2', '2', '2', '3', '2', '3', '2', '2', '2', '2', '3', '2', '2', '3', '2, 'said ceramic raw composition comprises at least one ...

Particle stabilized foam, and slurries, product, and methods related thereto

Номер: US20140272376A1
Принадлежит: United States Gypsum Co

Disclosed are cementitious product, as well as cementitious slurry, and method of forming the product. To reduce density in the cementitious product, foam is included in the slurry and in the method of forming the product. The slurry includes cementitious particles, water, and air bubbles such as from compressed air. Instead of using detergent chemistry at the gas/water interface of bubbles, the present invention uses a surface modifying agent for the cementitious particles in the slurry. The modified particles act to produce stable foam in the slurry. As an example mode of introduction, the surface modifier can be added (e.g., as solid or solution) directly into a bulk cementitious slurry that forms the product. As another example, the surface modifier can be added in a separate solution with water, air bubbles, and cementitious particles that serve as additive to the main cementitious slurry, where the separate solution is then added to the main cementitious slurry.
