The silicophosphoaluminates are crystallized out from the two-phases reaction mixtures comprising the resoures of silicon oxide aluminium oxide and phosphorus oxide, and a suitable orienting reagent. The silicon, phosphorus and aluminium in the silico-phosphoaluminates can be optionally substituted by other elements with valency of positive four, five and three. The resulting crystalline oxides possess ion -exchange activity and are easily changed into material having catalytic activity. |
