| titleOfInvention | Method for producing plate-shaped alpha alumina |
| abstract | The present invention relates to a method for producing plate-shaped alumina, and more particularly, to a method for economically and efficiently producing plate-shaped alpha alumina having no narrowing and agglomeration, having a narrow particle size distribution, and having excellent dispersibility. According to the manufacturing method of the plate-shaped alumina by the flux method, after heating the aluminum salt or transition alumina to 700 ~ 950 ℃ at a heating rate of 80 ~ 1800 ℃ / hr, and maintained for 0.1 to 5 hours, again 30 ~ 600 ℃ / After reheating to 1000-1400 degreeC at the temperature increase rate of hr, it is hold | maintained for 1 to 10 hours, and then furnace-cooled to room temperature, The average particle diameter is 10-50 micrometers, The particle thickness is 0.1-0.8 micrometer, A method for producing a plate-shaped alpha alumina having an aspect ratio of 50 to 500 is provided, and the plate-shaped alpha alumina prepared by the method of the present invention is free from twins, agglomerates, fine particles or fragments, and has a narrow particle size distribution. It has a particle size of 10 to 50 µm, a thickness of 0.1 to 0.8 µm, an aspect ratio of 50 to 500, and suspension suspension in water gives a beautiful streamline. It can be suitably used as a raw material for white pigments, resin fillers, polishing pads and the like.n n n n Plate, Alpha Alumina, Dispersibility |
