Specific Surface Area of Swaged UO2 Compact
Journal of Nuclear Science and Technology, 1965Specific surface area was measured on swaged UO2 compacts by B.E.T. method using Kr as adsorbate. The procedure for specimen preparation of swaged UO2 compact is discussed in the report. Measured values of cold swaged UO2 compact (88% T.D.) were mostly 0.51–0.70 m2/g, while those of hot swaged UO2 compact (94% T.D.) mostly 0.05∼0.13 m2/g.

The specific surface area of γ-Al2O3
Surface Science, 1972Abstract The specific surface area of γ-Al 2 O 3 (Alon) has been determined by three methods: A typical sample was 129 m 2 g by the BET (N 2 adsorption) method, 118 m 2 g by negative adsorption of sodium ion from dilute aqueous solution, and 117 m 2 g by differential capacity.

Specific surface area determination by TG/DSC
Thermochimica Acta, 1999Abstract The specific surface area is an important feature, greatly affecting the sintering behavior of ceramics and metallic powders. It is usually reported as a BET measurement. Similarly, for UO 2 powders, the stoichiometric O/U ratio also has an influence on the sinterability and can be measured by thermogravimetry.

Specific surface areas of new carbon adsorbents
Solid Fuel Chemistry, 2010We report on a mathematical description of the specific surface area of a carbonaceous adsorbent as a function of the specific surface area of the precursor carbonized material and as a function of percent burn-off during the gas-vapor activation of the carbonized material with carbon dioxide and steam for carbonized materials of various natures.

Abstract A method for the measurement of the specific surface area of powder samples weighing between 1 and 50 mg is described. The method is based on 85 Kr adsorption. A ratio test demonstrated that the method gives self-consistent data for samples of less than 10 mg. A cross-check, using 50-mg samples of uranium dioxide, demonstrated agreement to ±

Specific surface area and surface charges of some argentinian soils
Zeitschrift für Pflanzenernährung und Bodenkunde, 1997AbstractThe specific surface areas of nine argentinian soils obtained by adsorption followed the order N2 < ethylene glycol < H2O, attributed to the presence of smectites (verified by XRD analysis) and some organic coating. The H2O2 treatment of these soils modified the former order of surface area determined by different absorbents.

Rate of Evolution of the Specific Surface Area of Surface Snow Layers
Environmental Science & Technology, 2002The snowpack can impact atmospheric chemistry by exchanging adsorbed or dissolved gases with the atmosphere. Modeling this impact requires the knowledge of the specific surface area (SSA) of snow and its variations with time. We have therefore measured the evolution of the SSA of eight recent surface snow layers in the Arctic and the French Alps, using
