Applicant's summary and conclusion

Conclusions:
The measured density of Neodymium fluoride oxide, magnesium doped was 6.9 g/mL.
The relative density of Neodymium fluoride oxide, magnesium doped is 6.9.

Executive summary:

A known weight of the test item was placed in the sample cell and its volume determined by fluid displacement. The density of the test item was calculated from its weight and volume.

The measured density of Neodymium fluoride oxide, magnesium doped was 6.9 g/mL.

The relative density of Neodymium fluoride oxide, magnesium doped is 6.9.
