Abstract:
A maintenance-free stone tile is provided in which a super hard coating film having a pencil hardness corresponding to 12H or more (preferably to 12 to 15H) is used to produce a finish having a deep material feeling and a high quality, and glossiness of 80 or more, and be further able of keeping the coating layer good in water resistance, antifouling property, slipperiness, adhesiveness and no crack, over a long term, on a surface of a stone tile, such as a marble, artificial stone, terrazzo or ceramic tile. The tile is a stone tile having an inorganic coating layer causing a surface of the stone to have a pencil hardness of 12H or more and a mirror surface glossiness of 80 or more.
Abstract:
Provided is a production method of a β-sialon phosphor that europium ions are solid-solved in β-sialon, including a mixing process for mixing raw materials of the β-sialon phosphor; a burning process for burning the raw materials after the mixing process to form the β-sialon phosphor; a HIP treatment process in which the β-sialon phosphor after the burning process is subjected to a HIP treatment; an annealing process in which the β-sialon phosphor after the HIP treatment process is subjected to an annealing treatment; and an acid treatment process in which the β-sialon phosphor after the annealing process is subjected to an acid treatment. According to the production method of a β-sialon phosphor, a β-sialon phosphor excellent in luminescence intensity is obtained.
Abstract:
To provide a treatment agent for asbestos, which has a less influence on human body, the construction and the surrounding environment and can render the asbestos harmless evenly up to the inside of the bulky covering materials, which cover the wall, or the slate materials, and a treatment method of the asbestos using the same.A treatment agent for asbestos, which contains phosphoric acid of 0.5 through 3.0% by weight, hydrogen peroxide of 1 through 20% by weight, alcohol of 0.5 through 20% by weight and pure water and a treatment method of the asbestos using the same are described.

Abstract:
A method for producing a Si—SiC member for heat treatment of semiconductor, which is suitable for heat treatment of a semiconductor wafer with a large diameter and capable of reducing the contamination of the semiconductor wafer as much as possible is provided. Further, a method for producing a Si—SiC member for heat treatment of semiconductor capable of reducing the contamination of the semiconductor wafer as much as possible and causing no slip is provided. This method comprises the first step of kneading a SiC powder having a total metal impurity quantity of 0.2 ppm or less with a molding assistant; the second step of forming a compact from the kneaded raw material; the third step of calcining the compact; the fourth step of purifying the calcined body; and the fifth step of impregnating the purified body with silicon within a sealed vessel provided in a heating furnace body.
Abstract:
The application relates to a method for creating a pattern on a surface of a hydraulic binder-based composition, comprising applying by printing a deactivating composition (D1) or acidic composition (A1) to a part or to the whole surface of a hydraulic binder-based composition.
Abstract:
