【摘要】 采用"成核期积分平均速率法",运用阿累尼乌斯实验定律,求出仲钨酸铵结晶成核的表观活化能E表= 181.400kJ/mol,得出仲钨酸铵结晶成核速率常数与温度的关系式为kN=2.16×1026exp(-181400/RT)。
【Abstract】 According to Arrhenius theory,using the method of nucleation period integral mean rate,the apparent activation energy of ammonium paratungstate is calculated as 181.400kJ/mol.At the same time,the relational expression between ammonium paratungstate crystal nucleation rate and temperature is concluded as kN=2.16×
【Key words】 ammonium paratungstate; cystal; the method of nucleation period integral mean rate; nucleation rate constant; activation energy;
