Description of the invention (ι ·) The present invention relates to a kind of granular carbonic acid. People use carbonic acid to paste the mixture as a mixture, and the box is mixed with other materials. It is used to prepare contact glass, electric glass, and used to prepare high-temperature superconductor materials. ° Used as gas preparation International patent case WO state and other case publications < Barium carbonate) It has a surface area of 3G m2 / g. The area of the silk layer ^ indicates that the reactivity is not corrected. This is prepared by using barium hydroxide solution and carbon dioxide in a mixture of fibrinogens and f inhibitors. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The task is to provide a method for preparing-granular micronized barium carbonate with a relative surface area. These tasks are solved by the method of the present invention. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs for preparing granular, barium carbonate with a relative surface area of at least 32mV. The barium solution is mixed with carbon dioxide to form a reaction mixture, wherein about 12 liters to 2 liters of carbon dioxide gas per liter of solution is used to introduce the reaction mixture through a continuously operating mixing reactor, in which the shear force, thrust force and friction force The tools interact with each other at high relative speeds and act on the reaction mixture according to the Rotor-Stator principle. At the same time, a crystallization inhibitor is used in a portion of at least 1.8% by weight, relative to 100%. It is calculated based on the total number of carbonic acid and crystallization inhibitor, and the mixed reactant is directly added to the mixed reactor. After the reaction, the formed soil is taken out to test the carbonate, separated and dried. The size of this paper is applicable to China National Standard (CNS) A4 (210 X 297 public directors) -6-539648 A7 Printed by S, Invention Description of Employee Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, etc. And the miscellaneous force, it is the carbon dioxide that enters into the hydroxide infusion in the finest clear form. The carbon dioxide gas shown here in liters is under normal conditions. The minimum amount of crystallization inhibitor added is calculated as follows: In the amount of barium hydroxide, after accepting a stoichiometric reaction, the amount of silk carbonate generated is calculated. During the reaction, 'at least the crystallization inhibitor is added to the sum of the calculated barium carbonate plus the crystallization inhibitor, Its amount is at least U% by weight. For example, if the amount of barium hydroxide used is as much as 982 grams of barium carbonate, then at least 1.8 grams of crystallization inhibitor is added. The value of L8% by weight is reached by definition. The inventors have determined during experiments that crystallization inhibitors must often be found only partly in the precipitated product. When performing the method of the invention, micronized carbonic acid is obtained Among them, the BET-surface layer & is 32 m2 / g. Preferentially, it is between 32 and 60 m2 / g; higher rotation speed, higher concentration, and immediate addition of medium will result in higher surface area. Very suitable are some devices in which the rotor rotates at a high number of revolutions. The number of revolutions of the rotor is preferably between 2500 and 8000 revolutions per second. The residence time of the reaction mixture in the mixing and homogenizing device is preferred. For up to 5 seconds. From the formation of barium carbonate particles to their contact with the crystallization inhibitor, it takes up to two seconds, preferably one second. BET_The determination of surface area is based on a micropore-calculating Micr〇Mentics company The instrument is completed. The adsorption gas is nitrogen, and the measurement is in the liquid nitrogen temperature range of 0.001 to 0.1 Prel, which is completed using the BET equation.
