The present invention relates to the synthesis of luminophores and of reflective alumina for optimizing the emissive properties of a fluorescent layer.

Alumina, luminophores and mixed compounds, and associated preparation processes

The invention relates to a heat-transporting fluid and to the use thereof. The heat-transporting fluid of the invention is formed of an aqueous colloidal sol including water and up to 58.8 wt %, relative to the total fluid weight, in a-Al2O3 particles, the thickness of which is the smallest dimension and less than or equal to 30 nm 90% to 95% of said a-Al2O3 particles have a size less than or equal to 210 nm, among which 50% have a size less than or equal to 160 nm. The invention is of use in the field of cooling, in particular nuclear reactor backup cooling.

Colloidal dispersion of aluminum oxide

The present invention provides a slurry composition for chemical mechanical polishing comprising spinel particles having the formula AO&bull;xZ,O,wherein A is at least one divalent cation, Z is at least one trivalent cation, and 0.01&lE;x&lE;100. The present invention also includes a method of chemical mechanical polishing the surface of a substrate using slurry compositions that include these spinel particles. The slurry compositions of the present invention provide the desired level of planarization and selectivity for both metal and oxide surfaces. In addition, the slurry compositions of the invention can be prepared such that they are substantially free of alpha phase alumina particles and other high hardness particles to produce a scratch-free polished surface.
