Description
Summary:The changes in particle size distributions in bayerite and magnesium hydroxide on calcination are reported. In general, size distributions in calcined powders very closely resemble those obtained before calcination. Theoretical changes in particle volume, and hence in volume equivalent diameter, can be calculated from weight‐loss data and corresponding densities. Possible reasons for deviation from the theoretical size reduction ratio are also discussed.
