Effect of different granulation processes and powder particle sizes on uniformity of diamond distribution in the mixed powder
Published 2025-04-01“…The actual numbers of diamond particles in each sample were counted manually, the actual numbers of particles were compared with the calculated theoretical numbers of diamond particles and the deviation values were obtained. The averages and the ranges of the deviation values were used to determine the uniformity of diamond distribution in the mixed powder containing diamond.Results(1) From the morphology of the powder particles, it can be seen that the circular granulation produces spherical-shaped powder, the cold press crushing granulation produces irregularly shaped powder with distinguishable original particle morphology on its surface, and the diffusion crushing granulation produces irregularly complex shaped powder. (2) The loose packing ratio of powder produced by cold press crushing granulation is the highest, while the loose packing ratio of powder produced by disk granulation and diffusion crushing granulation is not significantly different. …”

Influence of the material of weighing bottles on loss-on-drying reproducibility
Published 2022-07-01“…Results: Four batches of model samples were prepared and standardised in terms of average mass using Shewhart’s charts. The effect of weighing bottle materials was most pronounced at low residual moisture contents (less than 0.5%), with the relative standard deviation (RSD) values for the results obtained with glass and metal weighing bottles reaching 76% and 35%, respectively. …”
