This paper outlines technologies for production of flyash based zeolite (FAZ) A, X & Y with significant reduction in the cost of production of FAZs due to substitution of conventionalraw material, viz. sodium silicate and aluminate with flyash. The cost of production of FAZs is estimated to be 25% lower than the indegenously available commercial zeolites. The high exchange capacity of FAZ-A indicates its potential as a substitute for phosphatic detergent builder. The high surface area and thermal stability of FAZ-Y indicates its suitability as a catalyst in specific areas such as automotive exhaust and detergent.
