<p>A METHOD FOR PRODUCING BOEHMITE PARTICLES INCLUDES SUBJECTING POWDER OF ALUMINUM HYDROXIDE TO HYDROTHERMAL REACTION TOGETHER WITH A NUCLEATION AGENT, THEREBY OBTAINING BOEHMITE PARTICLES HAVING AN AVERAGE PRIMARY PARTICLE SIZE OF 0.6 µm OR LESS AND INCLUDING PRIMARY PARTICLES EACH HAVING A HEXAHEDRAL SHAPE. A METHOD FOR PRODUCING ALUMINA PARTICLES INCLUDES: DRYING THE BOEHMITE PARTICLES PRODUCED BY THE ABOVE DESCRIBED METHOD; CALCINING THE BOEHMITE PARTICLES, WHICH HAVE BEEN DRIED, TO OBTAIN ALUMINA PARTICLES; AND DISINTEGRATING THE OBTAINED ALUMINA PARTICLES.</p> |
