<p>PURPOSE:To provide the ceramics for prepn. of various kinds of aq. solns. as calcination for primary utilization and to provide the vessel, etc., for changing the taste as the calcination for secondary and ternary utilization by controlling the calcination temp. of a stock prepd. by adequately compounding zeolite, clay, etc. CONSTITUTION:The vessel is formed by compounding 10 to 90% zeolite, 10 to 70% clay, and 0 to 40% fossil animal and plant components. This vessel is calcined at 500 to 1150 deg.C, 500 to 1280 deg.C and 900 to 1280 deg.C to form the porous ceramics for primary, secondary and ternary utilization. Glaze, etc., are applied thereon to eliminate leakage. Such vessel is utilized for holding and transferring of the aq. soln. The pH and mineral components of various kinds of the aq. solns. are controlled by utilizing the exchange and adsorption of ions in the primary calcination. The ceramics is used as the vessel for changing the taste in the secondary and ternary calcination.</p> |
