Compositions useful for foundry processes such as green sand casting are discussed. The compositions may comprise an aggregate, at least one inorganic binding agent, and at least one high aspect ratio silicate. For example, the composition may comprise sand, one or more clay materials serving as a binding agent, and a high aspect ratio silicate chosen from mica, talc, or a combination thereof. The composition may be formed into a green sand mold for use in casting molded articles. Incorporation of the high aspect ratio silicate may help to improve the quality of the casted article.

The present invention relates to a dry refractory particulate composition comprising a zeolithic microstructure, to a green body and to a refractory lining formed therefrom, and to uses thereof.

To provide the friction material for the disc brake pad manufactured by forming the NAO friction material composition, enabling to restrain the brake vibration during braking in a high temperature. The NAO friction material composition does not contain the copper component but contains, relative to the entire amount of the friction material composition, 5-9 weight % of the binder with 1-4 weight % of the silicone rubber modified phenol resin as a part of the binder, the fiber base, 1-4 weight % of a cashew dust as the organic friction modifier, 0.5-3 weight % of a fused silica with the average particle diameter of 15-40 m as the inorganic friction modifier, and 0.1-2 weight % of the electromelting zirconium silicate beads with the average particle diameter of 10-30 m as the lubricant.

A gasket material for high pressure high temperature presses, comprising: a proportion of a clay mineral a proportion of a hard material for increasing the viscosity of the clay mineral a proportion of a binder selected from the group of borate binders, phosphate binders, and mixtures thereof.

A full-fiber burner brick and a preparation method thereof, comprising mixing alumina crystal fiber and amorphous ceramic fiber with both of them being a combination of fibers of different lengths gradations, and moreover adding fine powder fillers of different particle size gradations and supplementing other additives. This enables the internal structure of the product more uniform, increases the bulk density of the product, and also benefits the suction filterability of fiber cotton blank, and is conducive to forming and improving the strength of the blank. The surface of the brick body is further provided with a coating, which can effectively protect the cotton fiber of the brick body fiber from harsh environments, improve its high temperature resistance, and help to extend the service life of the burner brick.
