串联速率法研究仲钨酸铵晶体线生长速率
Study on the Linear Growth Order of AmmoniumParatungstate Crystal by the"Method of Series Rate
【摘要】 将结晶成核期后晶体的生长阶段作为线生长速率测定的时间范围,采用“串联速率法”研究了仲钨酸铵(APT)的晶体线生长级数。NH4Cl—NH3·H2O—H2O系和NH3·H2O—H2O系测定的APT晶体线生长级数分别为0.69和0.82。
【Abstract】 The crystal growth period after the crystal nucleation period is performed as the measuring time range of crystal growth rate. The method of series rate is used to study the linear growth order of ammonium paratungstate (APT) crystal. The measured linear growth order is 0.69 and 0.82 respectively in the NH4Cl-NH3·H2O-H2O system and NH3·H2O-H2O system.
