The present invention provides a method for manufacturing aluminum hydroxide powder highly fillable in a resin as a filler, comprising the step of grinding raw aluminum hydroxide using a kneader mixer.

Method for manufacturing aluminum hydroxide powder

Aluminum hydroxide is disclosed, wherein a mean particle size of a secondary particle is from 0.1 to 8 .mu.m, a BET specific surface area is not less than about 30 m.sup.2 /g and a pore size distribution has a maximum value within the range from 5 to 100 nm, a method for producing the same, and a method of using the same, comprising containing the same in a rubber, a method for using the same as a filler of a rubber composition for tire tread, and a rubber composition for tire tread using the same.

Aluminum hydroxide, method for producing the same, and method of use of

A method for producing .gamma.-form lithium aluminate powders usable as a material for an electrolyte tile of molten carbonate fuel cells which comprises mixing aluminum alkoxide with one member selected from the group consisting of the lithium salts of inorganic and organic acids, lithium hydroxide and lithium oxide in the presence of a non-aqueous solvent, carrying out reaction with addition of water of 1.5 to 20 moles (including water of crystallization contained in the lithium compound) based on 1 mole of aluminum alkoxide with stirring, and removing the solvent to obtain a solid matter which is then calcined at a temperature in a range of from 650.degree. C. to 1000.degree. C.
