Title: Production of calcium carbonate
Inventor: FUJIWARA TOSHIO
IPC: C01F11/18
Filed: 1986-03-08
Abstract: PURPOSE:To produce columnar CaCO3 having calcite type crystal structure advantageously in industrial scale by adding a specified compd. when gaseous CO2 is allowed to react with Ca(OH)2 by a contact reaction of gas with liquid and aging obtd. CaCO3 slurry. CONSTITUTION:In a gas/liquid reaction of CO2 with Ca(OH)2 to form CaCO3, at least one among Mg salts (e.g. MgCl2, MgCO3, etc.) and chlorine compds. (e.g. NaCl, ZnCl2, etc.) is (are) added before completion of the carbonating reaction, and obtd. CaCO3 slurry is then aged. Thus, calcite type columnar CaCO3 is produced advantageously in an industrial scale. When the obtd. CaCO3 is used as coating pigment for white printing paper, the gloss of the coated paper before and after printing, the ink receptivity, and the viscosity of the coating material at high speed shear plane are all satisfied at the same time. When the CaCO3 is used for filler for tissue paper, expensive TiO2 is saved because the CaCO3 has superior opacity and whiteness as compared to conven tional spindle-shaped CaCO3.

Abstract: PURPOSE:To avoid a disconnection of Al at a through hole by a method wherein the second oxide film having a B density lower than a P density is developed after the through hole is made on an oxide film containing B and P and the whole surface is dry-etched. CONSTITUTION:A substrate 11 is heat-treated after an oxide film 12 containing B and P is developed on it. Then, through holes 14 are made on the substrate by dry etching. After that, an oxide film 15 is developed which contains B and P and which have a B density lower than a P density on the substrate 11. Then the whole surface of the substrate 11 is heat-treated and then dry- etched. Since the second oxide film 15 contacts the substrate 11, an overhang of the though holes caused by a surface tension can be avoided in the thermal treatment. Consequently, a good through hole shape can be attained and a disconnection of Al at the through holes is avoided.
