Process for preparing hydrotalcite and brucite type posite charged layers |
| 摘要 |
An improved process is described for the preparation of surface modified hydrotalcite. The process comprises reacting a precursor of magnesium and aluminium in the presence of suitable alkali carbonate at high temperature. The product has a BET surface area of <=20 M<SUP>2</SUP>/gm and average particle size of <=0.5 mum and is useful as halogen scavenger and fire retardant.
