Abstract: PROBLEM TO BE SOLVED: To provide a method for synthesizing a tubular aluminum silicate inexpensively, safely and in a large quantity, applicable for a fuel storage material, an autonomous humidity control material, a deodorizing material, an organic contaminant adsorbing material or the like. SOLUTION: The objective high purity tubular aluminum silicate is produced by forming a precursor from a solution prepared by mixing an inorganic silicon compound solution having 1-500 mmol concentration with an inorganic aluminum compound solution having 1-1,000 mmol concentration to be a prescribed silicon/ aluminum molar ratio and, after removing coexisting ions to reduce the concentration of the ions in the solution, the aging by heating and recovering and cleaning the formed and deposited solid portion. The tubular aluminum silicate is synthesized more inexpensively, safely and in a large quantity compared to the conventional method.

Abstract: PROBLEM TO BE SOLVED: To inexpensively produce an antibacterial porous structure by coprecipitating metal ions having antibacterial properties at the time of precipitating a hydroxide by adjusting the hydrogen ion concn. of a metal salt aq. soln. with an alkaline soln. and heat treating the hydroxide gel obtained by agitating the coprecipitated matter in hot water bath. SOLUTION: In the case of producing a moisture regulating material having the function of preventing the propagation of bacteria etc., even under the wet condition in which steam is absorbed, a gal in which the hydroxide is uniformly dispersed is prepared by executing, for example, a treatment such as agitation in a hot water bath after adjusting the aq. soln. to the hydrogen ion concn. at which the hydroxide is precipitated by adding a hydrogen ion concn. adjusting agent the metal salt aq. soln. containing the metal ion having antibacterial properties. The gel is converted to a porous oxide by causing a dehydration reaction by keeping the gel at a prescribed temp. for a prescribed time after drying the gel in a thermostatic bath of 100 deg.C, for example. The porous material is obtained by executing particle size adjustment by mechanical crushing by using, for example, a mortar etc., and by sifting etc., and by executing washing treatment etc., at need after the heat treatment.

Abstract: PROBLEM TO BE SOLVED: To provide the inexpensive production method of the moisture regulating material exhibiting the autonomous moisture regulating function usable over a long period of time. SOLUTION: A porous oxide is produced by precipitating hydroxide by adjusting the hydrogen ion concn. of metallic salt aq. soln. with ammonia aq. soln. etc., and subjecting the hydroxide gel obtained by agitating the hydroxide in a hot water bath to heat treatment. In this way, the moisture regulating function is exhibited by autonomously executing the absorption and emission of steam under the humidity condition of about 50-70% relative humidity. Then the autonomous moisture regulating function repeatedly usable over a long period of time is supplied.

Abstract: PROBLEM TO BE SOLVED: To inexpensively obtain interior wall material that can prevent dew condensation, secure the comfortable space by controlling the humidity indoor and has antifungal properties by molding and calcining a plastic kaolinite mineral and making it porous by soaking it in an alkali solution. SOLUTION: Kaolinite mineral is adjusted in its particle size, for example, less than 30 mesh, preferably 70 mesh, molded, calcined, peferably at 900-1,100 deg.C for 1-24 hours to effect the phase separation into the alumina phase and the amorphous silica phase, then soaked in an alkali solution of strong alkalinity (for example, KOH solution), for example, at 50-90 deg.C for 12-48 hours thereby selectively dissolving the alkali-soluble components as the amorphous silica and the like to a porous form, washed, dried thereby producing a porous structure body. In another embodiment, a suspension of kaolinite mineral is sprayed to the surface of an unglazed pottery in a suitable shape to form the surface layer of the kaolinite, the calcined in a similar manner and treated with alkali.

Abstract: PROBLEM TO BE SOLVED: To provide a porous material which has good water resistance, heat resistance, and corrosion resistance and keeps the humidity of living environment optimum in an energy saving manner by absorbing/desorbing water in a living space autonomously. SOLUTION: A humidity conditioning material is composed of a composition of a porous material having an autonomous humidity conditioning function. The composition which is formed using an organic substance having a surfactant or a long chain alkyl group as a casting mold is made from one or more kinds of substances selected from a group consisting of aluminosilicate and transition metal elements. The porous material is prepared by a process in which an organic substance having a surfactant or a long chain alkyl group, after being enclosed with silicon dioxide or transition metal oxide, is polymerized, and the product is burned or extracted to remove the organic substance. The average diameter of the pores is 2-6nm, and the material has an autonomous humidity conditioning function at a relative humidity of 40-70%.

Abstract: PURPOSE:To solidify MgCO3 or a material consisting essentially of MgCO3 under mild conditions. CONSTITUTION:MgCO3 or a material consisting essentially of MgCO3 is solidified by adding a solubilizing material such as alkali salt, etc., to it or using the solubilizing material as the autoclave treating solution and subjecting the resulting mixture to autoclave reaction under consitions of comparatively low temp. and low pressure. Thus, MgCO3 or a material consisting essentially of MgCO3 is easily and efficiently solidified under mild conditions of comaratively low temp. and low pressure by only treating it through using a conventional device, i.e., an autoclave. Accordingly, the reduction in energy consumption and cost in the MgCO3 solidification technique can be attained.

Abstract: PURPOSE:To solidify CaCO3 and/or MgCO3 or a material consisting essentially of them under mild conditions. CONSTITUTION:CaCO3 and/or MgCO3 or a material consisting essentially of them are mixed with at least one Ca or Mg based material selected from CaO, Ca(OH)2, MgO and Mg(OH)2 and a silica based material and thereafter, the resulting mixture is solidified by utilizing an autoclave reaction. Thus, these raw materials are easily and efficiently solidified under mild conditions of comparatively low temp. and low pressure by only treating them through using a conventional device, i.e., an autoclave to obtain a high strength solidified body and accordingly, the reduction in energy consumption and cost can be attained by using this method. Therefore, CO2 in a waste combustion gas can be fixed and recovered as CaCO3 and/or MgCO3 and the recovered material is solidified at a low treating cost to effectively utilize the solidified product for construction and civil work materials, etc.
