Abstract: PURPOSE:To improve heat resistance, chemical resistance, ion exchange ability, antimicrobial property, electrically insulating properties and neutron absorbing ability of a fibrous substance by coating the surface of a fibrous substance with aluminum borosulfate or aluminum borate. CONSTITUTION:One or more compounds selected from sulfuric acid salts of Al, hydroxides of Al, hydroxides of alkali metals, carbonic acid salts of alkali metals, aluminic acid salts of alkali metals, carbonic acid salts of ammonium and ammonium hydroxide are made to react in the presence of a fibrous substance such as fibrous alkali metal salt of titanic acid, a fibrous boric acid transition metal salt, a fibrous alkaline earth metal salt of boric acid or ZnO whisker in an equivalent ratio of 1:(4.5-6.0) at 5-80 deg.C for 1-5hr. Then, a boron compound is added thereto and the fibrous substance is made to react with the boron compound at 10-200 deg.C for 1-8hr and the reactional product is washed with water and dried to coat the surface of the fibrous substance with aluminum borosulfate or aluminum borate.

Abstract: PURPOSE:To selectively and efficiently remove ammonium ion in seawater by the adsorbent by incorporating an ion-exchangeable alkali metal ion in the molar ratio of 0.05-3 to Al2O3 into the adsorbent contg. a 2.5-25 molar ratio of SiO2 and Al2O3. CONSTITUTION:An ion-exchangeable alkali metal ion is incorporated in the molar ratio of 0.05-3 to Al2O3 into the adsorbent contg. a 2.5-25 molar ratio of SiO2 and Al2O3 to obtain the desired selective adsorbent for ammonium ion. The aluminum salt or aluminate and silicate in which the molar ratio of SiO2 to Al2O3 is controlled to 2-20 are dripped into water in an alkaline region at pH8-12, the liq. reactant is then adjusted to pH 4-9 by an acidic soln. to deposit the desired material, and the deposit is separated and dried to obtain the desired material. The material is appropriately calcined at 15-400 deg.C to obtain a better material.

Abstract: PURPOSE:To obtain potassium titanate aluminate whiskers by forming whiskers having a compsn. represented by a specified formula, prescribed fiber diameter, fiber length and aspect ratio. CONSTITUTION:One or more kinds of Al compds. such as Al2(SO4)3 and Al(OH)3 are added to potassium titanate fibers dispersed in water and they are brought into a reaction at 5-80 deg.C to prepare potassium titanate fibers surface-coated with the Al compds. A flux such as K2SO4 is added to the surface-coated fibers by 50-90wt.% of the total amt. and they are mixed, press-compacted, fired at 900-1,300 deg.C and slowly cooled to form a fired compact. This compact is boiled in water, washed with water, separated by filtration and dried to obtain the objective potassium titanate aluminate whiskers having a compsn. represented by the formula KxAlxTi8-xO16 (0.8
