摘要： PURPOSE:To obtain stone-like pottery having excellent mechanical strength by mixing feldspar powder with Portland cement, curing resultant aqueous slurry with hydration in a shaping mold and firing resultant molded article. CONSTITUTION:A mixture of inorganic principal components containing 5-40wt.% Portland cement and 60-95wt.% feldspar powder is dispersed into water to prepare an aqueous slurry. Next, said aqueous slurry is cured by hydration in a shaping mold and resultant cured molded article is fired at a temperature of 1000-1600 deg.C to afford the aimed pottery. As used Portland cement, white portland cement is preferable. white Portland cement contains a slight amount of colored substance such as iron and able to improve whiteness of resultant pottery.

摘要： PURPOSE:To make it possible to obtain a water soluble calcium salt composition readily soluble in water and readily absorbable into a living body by mixing a calcium phosphate ingredient with an aqueous solution containing a carboxylic acid compound ingredient and dissolving the calcium phosphate ingredient in the above-mentioned solution. CONSTITUTION:A calcium phosphate compound ingredient consisting of at least one kind selected from a hydroxyapatite obtained from tricalcium alpha-phos phate, tetracalcium phosphate and bone of an animal is mixed and dissolved in an aqueous solution of carboxylic acid compound ingredient consisting of at least one kind selected from citric acid, malic acid, gluconic acid, lactic acid and acetic acid and sodium salt or potassium salt of these specific carboxylic acids so that total content of carboxyl group is >=3mol based on 1mol calcium content to give a mixed and dissolved liquid. Water content of the resultant liquid is evaporated and removed to afford a condensed liquid. Thereby calcium can be readily absorbed into a living body by adding the condensed liquid to a food or taking the condensed liquid in.

摘要： PURPOSE:To obtain an antibacterial antimildew resin article which is a sanitary article such as a toilet seat and can fully exhibit antibacterial antimildew properties by washing a molding made of a resin containing a calcium phosphate compound carrying a specified metallic ion with an acid. CONSTITUTION:The article is obtained by adding an inorganic antibacterial antimildew agent comprising a calcium phosphate compound carrying ions of an at least one metal selected from among silver, copper and zinc to a resin and washing a molding made of this resin with an acid. The antibacterial antimildew effect of the calcium phosphate as a carrier can enhanced by the interaction with the acid, and therefore this compound is effective to give antibacterial antimildew properties to a resin even when added in such a small amount as not to impair the properties of the resin. Therefore, the article can desirably be used as a sanitary article, such as a toilet seat, a bathtub or a washstand, which needs to be kept clean and beautiful.
