| Abstract: | Through one step method of neutralizing and polymerizing,the PTTP is prepared from both superphosphoric acid and potassium carbonate raw materials.The influences of reactant's mixture ratio and neutralization value on product quality are studied to obtain optimum technological parameters.With the reactant's mixture ratio n(K_2O)/n(P_2O_5) of 1.85,and neutralization value of 64%,the product w(K_5P_3O_10) of more than 93% is obtained. |
