摘要： A white reflective powder is used as the final grinding medium for preparing the surfaces of inorganic scintillation crystals. After grinding to final tolerances, a certain amount of the grinding powder is left embedded in the surface of the crystal. This powder minimizes absorbance and enhances the energy and spatial resolution in the detection of scintillation events.

摘要： Used frying oils and fats are regenerated and made suitable for re-use by treating them with a composition consisting of a mixture of activated bentonite clay or magnesium silicate with a gel-derived alumina. The treating composition contains from about 15% by weight to about 75% by weight gel-derived alumina, balance activated clay or magnesium silicate.

摘要： A light-reflective flowable and curable composition comprises a resin containing light-reflective solid particles in an amount and of average particle size sufficient to provide the desired light reflectance/transmittance characteristics to the cured composition. Preferably, the composition is self-levelling and the solid particles comprise magnesium oxide, barium sulphate, aluminium oxide or mixtures thereof. The compositions of the invention are useful as reflective coatings in various applications, such as for radiation detector devices including scintillator crystals. For instance, a scintillator crystal block (1), mounted on a base (4) within a housing (7), has channels or grooves (3) separating it into elements (2) and these are optically isolated from one another by means of the light-reflective curable composition.
