The present invention relates to a coating composition comprising: 10 to 80 wt % of cerium oxide comprising a dopant based upon the total weight of the composition, wherein said dopant is selected from iron oxide, cobalt oxide, chromium oxide, lanthanum oxide, or mixtures thereof, and the atomic ratio of dopant metal to cerium is in the range 0.01:1 to 0.5:1; and 10 to 50 wt % of binder based upon the total weight of the composition.

A pigment granule having an irregular polyhedral shape with rounded edges and a method for the production of the granules by the use of a high speed agitated granulating machine provided with agitating means for agitating a pigment substance for granulation, spray means for spraying or injecting a binding liquid on the pigment substance while the mixture is processed through the turbulizer and drying means for drying the particles, characterized by effecting the production by causing the means to act on the substance for granulation simultaneously thereby performing the agitating and granulation.

Provided are: a coated sand having improved fluidity and being capable of improving a filling rate of a casting mold to be obtained; and a coated sand for advantageously manufacturing a casting mold having excellent strength, which coated sand provides a casting mold with good mold-releasability and collapsibility, gives cast products a favorable casting surface, and effectively improves sand adhesion on cast products. The coated sand is formed as a dry granular material having fluidity at room temperature, in which the surface of a refractory aggregate is coated with a solid layer of a water-soluble inorganic binder, and spherical particles of silicone resin having binder-repellency exist on the surface of the binder layer, or form a layer on the surface of the binder layer, a part of the spherical particles being not covered with the water-soluble inorganic binder and being exposed.

A plaster composition includes a joint compound/drywall mud and from about 0.5 wt % to about 10 wt % silica (e.g., amorphous silica, hydrophilic fumed silica, and/or hydrophobic fumed silica). The plaster composition may be a repair composition. The repair composition may be dispensed as an aerosol using a propellant. The repair composition may be useful for repairing “popcorn” textured ceilings.

An appliance cabinet includes a structural envelope having an exterior surface and an interior surface that defines an insulating cavity, wherein the insulating cavity defines an at least partial vacuum. A plurality of silica-based agglomerates are disposed within the insulating cavity, wherein each agglomerate of the plurality of silica-based agglomerates includes silica-based powder insulation material that is water-densified and is at least substantially free of a material binder. A secondary insulation material is disposed within interstitial spaces defined between the plurality of silica-based agglomerates, wherein the plurality of silica-based agglomerates defines an interior structure that resists inward compressive forces exerted as a result of the at least partial vacuum defined within the insulating cavity.

The invention discloses a bionic laminated thermal insulation material, which imitates a multi-thin laminated and thin-layer micro-pore structure of Sequoia sempervirens bark with fire resistance, corrosion resistance and excellent thermal insulation performance. A low thermal conductivity microporous powder is used as main raw material, while reinforcing agent, plasticizer and porosity agent are added to form microporous thin-layer units, and each thin-layer unit is bonded and laminated to make a laminated thermal insulation material. The thermal conductivity of the finished products is as low as 0.02˜0.05 W/m.Math.k, with good thermal insulation and mechanical properties, which can be used in a temperature range below 1000° C., with better thermal insulation and energy-saving effect and toughness than ordinary thermal insulation materials, significantly reducing the thickness of the insulation layer, and can be widely used in industrial furnaces, thermal engineering devices, insulation pipes and other fields.
