Experiment on determination conditions of particle size of lithium manganate by laser particle size analyzer

Determination conditions of particle size of lithium manganate sample were studied by malvern laser particle size analyzer(Mastersizer 2000).The influences of the main factors,such as obscuration,pump speed,intensity,and time of ultrasound were analyzed,and the appropriate determination conditions were selected according to the results.The suitable conditions were using deionized water as dispersant,ultrasonic time of 1 min,ultrasonic intensity of 8.00,pump speed of 2 400 r/min, and obscuration 5%.By replicate test,it could be concluded that the repeatability and reliability of the data were fine,and it was feasible to use malvern laser particle size analyzer to determine the particle size of lithium manganate in these conditions.
