In literature:

Magnesia (magnesium oxide) is better and is most extensively employed.
"Creative Chemistry" by Edwin E. Slosson
Magnesium oxide, sometimes called magnesia or magnesia usta, resembles lime in many respects.
"An Elementary Study of Chemistry" by William McPherson
It is virtually a compound of the two oxides, aluminum oxide and magnesium oxide.
"A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public" by Frank Bertram Wade
Then, by burning magnesium ribbon, and weighing the product, the student easily finds the relative weight of magnesium and oxygen in the oxide.
"Scientific Culture, and Other Essays" by Josiah Parsons Cooke
The lid of a biscuit box just in front of the frame does very well to catch the white magnesium oxide formed by burning.

In science:

In the visible region of the optical spectrum volume disordered media, e.g. compacted powdered barium sulphate, and freshly smoked magnesium oxide are used as Lambertian diffusers.
Design of one-dimensional Lambertian diffusers of light
The second group of superconductors incorporates low-dimensional and nonmagnetic compounds, such as A-15 superconductors, the metal oxide Ba1−xKxBiO3 , the magnesium diboride MgB2 and a large number of other binary compounds.
Route to Room-Temperature Superconductivity from a Practical Point of View
The discovery of superconductors such as magnesium diboride and iron pnictides[2, 3] opened new horizons in the landscape of superconductivity research, fueling renewed interest in the quest for high-temperature superconductivity in materials other than the copper oxides[4, 5].

The 6He target consists either of a water cooled tungsten core or of a liquid lead core which works as a proton to neutron converter surrounded by beryllium oxide [128], aiming for 1015 fissions per second. 18Ne can be produced by spallation reactions, in this case protons will directly hit a magnesium oxide target.
Future neutrino oscillation facilities
In the next section, the example of the optical response of a thin silver film deposited on a magnesium oxide substrate allows to describe in more details the position of the problem.
