On the other hand, both investigations used powder samples embedded in polyethylene (PE) pellets for the measurements.
Any parent who has used powder formula to feed their baby knows that measuring the formula, making sure the water is clean and at room temperature, and mixing the formula and water is a challenging task.
MgH2 was ball-milled for 10, 30, and 40 h to examine the effect of ball-milling on the properties of the used powder.
The technique uses in-line, non-contact monitoring of the blending process, eliminating the bias introduced by commonly used powder sampling techniques.
Two types of calcite seed were used: powder with a specific surface area of 1.29 m2/g (reported by manufacturer; J.T. Baker) and single Iceland spar crystals of typical dimension 10 mm × 6 mm × 5 mm (Ward's Scientific).
X-ray diffraction analysis of the investigated samples was performed when used powder diffractometer «STADI-MP» (STOE, Germany) with curved Ge (111) monochromator and radiation of CuKα (λ = 1.54056 Å).
