FORMATION OF ZEOLITE CRYSTAL
PURPOSE:To improve adhesiveness by immersing a porous material in an aqueous solution or gel to form zeolite and heating the porous material in a pressure container at a specific temperature. CONSTITUTION:An aqueous solution of NaAlO2 is mixed with an aqueous solution of Na2SiO3 to form a gel. An in...

| description | PURPOSE:To improve adhesiveness by immersing a porous material in an aqueous solution or gel to form zeolite and heating the porous material in a pressure container at a specific temperature. CONSTITUTION:An aqueous solution of NaAlO2 is mixed with an aqueous solution of Na2SiO3 to form a gel. An inorganic porous material such as Al2O3 is immersed in the gel and the porous material is heated in a pressure container at about 150-200'C for about 5-20 hours to give analcime of spherical crystal having excellent adhesiveness on the porous material. An aqueous solution of NaAlO2 is mixed with an aqueous solution of Na2SiO3 and an aqueous solution of NaOH to prepare an aqueous solution. An inorganic porous material is immersed in the aqueous solution and heated in a pressure container at about 150-200 deg.C for about 5-20 hours to give cancrinite of prismatic crystal having excellent adhesiveness on the porous material. |
