NAC standard
Dear friends! I have a question regarding the NAC transmission diffraction standard, which is Na2Ca3Al2F14. Is this standard safe in use, i.e., do I need any special safety when grinding it?

...don't breathe it in, don't eat, nor drink, and wear safety glasses,... Lovely :) Zitat von Andy FITCH fi...@esrf.fr: Dear ?ukasz, NAC is not a standard as it has never been subjected to any sort of formal procedure to ascertain its characteristics. Indeed each batch can be different. However, it is often highly crystalline, and so gives sharp peaks in a powder diffraction pattern, depending on which batch of sample it is. In terms of safety in handling it, I would suggest using normal safe powder-handling procedures; don't breathe it in, don't eat, nor drink, and wear safety glasses, lab coat, etc. . But why are you grinding it? Won't that affect the nice microstructure you're exploiting? And if it ever were certified as some sort of standard, grinding it is not the thing to do.

Lovely :) OK :-) AVOID breathing it in, don't eat, nor drink IN A LABORATORY, and wear safety glasses... It's not a joke. Those precautions should be second nature, especially in a chemistry or radiation laboratory.

Re: Na2Ca3Al2F14 (NAC) standard
be careful NAC is a great standard, but it is not certified, and different batches of the material have different broadening Nice to calibrate the angles, pay attention to calibrate the FWHM.
