Pharma and halogen grade synthetic hydrotalcites (SHT) from bitterns
Implementing Organization
Project Overview
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 20M2/gm and average particle size of 5 micorns and is useful as halogen scavenger and fire retardant
