Influences of Neutralization Crystallization on the Particle Size of Ta_2O_5 Powder AITranslate
Abstract AITranslate
Ta2O5 powder was prepared by neutralization crystallization and calcination.The influences of the six factors in the process of neutralization crystallization on the Ta2O5 particle size were studied including the concentration of tantalum solution,the initial pH of tantalum solution,crystallization temperature,ammonia concentration,ammonia flow rate and stirring speed.The optimal experimental conditions are as follows：the concentration of tantalum solution is 95 g/L,the initial pH of tantalum solution 1.80,crystallization temperature 60 ℃,ammonia concentration 8.0 mol/L,ammonia flow velocity 1.0 mL/min,and stirring speed 40 r/min.Prepared under the above conditions,Ta2O5 powder has the largest average particle size of 1.80 μm and fully meets with the production requirement.
