THE MANUFACTURING METHOD OF HIGH PURITY ALUMINA CERAMIC BALLS USING WASTE ALUMINUM DROSS

摘要

Aluminium scrap slag is utilized the present invention relates to a kind of manufacture high-purity alumina ceramic ball. More particularly, this method comprises: step 1 is rapid, aluminium hydroxide is recycled from waste aluminum dross; The aluminium hydroxide of second step grinding and sintering recycling is to prepare aluminium powder; Third step mixes aluminium powder, and inorganic bonding agent, organic bond and solvent, which prepare ceramic pellet and generate ceramic ball, passes through purification; Four steps, the dry ceramic ball generated; 5th step calcines the ceramic ball of the drying, 800 to 1000& deg; C; And the 6th step, heat treatment ceramic ball is fired, 1500 to 1700& deg; C. The present invention can effectively recycle aluminum metal from above-mentioned waste aluminum dross, and high-purity alpha-alumina manufacture high-purity alumina ceramic ball surface is made using identical. The minimum dross of energy of the present invention handles aluminum dross by recycling waste and old industrial waste, reduces costs, environmental correclation is protected to join. The present invention can also reduce the progress environmental protection of ceramic cost manufacture high-purity alumina ceramic ball, economy. ;The 2015 of copyright KIPO submissions
