calcium turnings ; magnesium turnings

Protocol number:	M090150
Industry:	Chemistry, Metallurgy
Feed Size:	2,5cm
Desired Fineness:	---
Quantity:	< 10 g
Recommendation:	A grinding with a planetary ball mill (as desired) is not possible. Both samples use to be too ductile (became flat out).

Result 1

	Planetary Mill PULVERISETTE 5 classic line with 2 grinding bowl fasteners main disk speed: 400 rpm
Equipment:	250 ml Zirconium oxide (ZrO2) grinding bowl + 6x 30 mm grinding balls made of ZrO2
Feed quantity:	7,1 g
Feed Size:	2,5 cm
Additive:	40ml Hexane
Grinding time:	5 min
Final fineness:	ductile - flakes
Comments:	The elemental Calcium uses to be very ductile. The pieces will flat out and stick to the balls. The size of the balls becomes increased by the covering Calcium flakes. A further grinding in a ball mill is not possible. See attached photos. The elemental magnesium uses to conduct the same way as Calcium does (the same mechanical characteristics). Therefore, we did not test the sample and send it back untouched.
