REACTION AND MIGRATION OP SODIUM IN THE SYSTEM SODIUM OXYGEN ~ ALUMINA
… diffusion or reaction was observed for sodium metal in the absence of oxygen over the entire temperature range. When oxygen was Included in the above forms, a large corrosion reaction to form Na20A1203 occurred wherever liquid sodium oxide was in contact with alumina, and above I3OOK B …

Thermal Performance Study of Liquid Metal Fast Breeder Reactor Insulations
… was further selected to be examined in sodium and sodium oxide environments. The emissivity of stainless steel 304 used in comprising the insulations was measured by employing infrared technology.

Alkali Silica Reaction Mitigation Using High Volume Class C Fly Ash
… acid) and a basic pH pore solution (Calcium Oxide, Potassium Oxide, and Sodium Oxide). ASR causes deleterious expansion within concrete, which can cause durability issues decreasing the life span of concrete. ASR in concrete has been found in increasing quantities since its discovery in 1940 …

Corrosion by molten mixtures of sodium carbonate and vanadium pentoxide
… of heavy petroleum fuels which contain sodium and vanadium becomes very severe when the temperature of the metal exceeds 550 to 600°C, thus placing undesirable limitations on both the manufacturers and users of heavy fuel oil fired boilers and turbines. To contribute to the understanding …

The performance of a blended PFA/GGBS alkali-activated concrete using a silica fume-based activator
… activated using an alkali source. Nevertheless, sodium silicate is an attractive ‘alkali activator’ but has been reported to contribute up to 75% of the total embodied carbon in AAC. This research reports on the development of an eco-friendly alternative (sodium silicate) activator derived from …

Electrochemistry of systems containing aluminum phosphate dissolved in fused borate and phosphate mixtures
… most frequently used. It is known that aluminum oxide is peptized by aluminum chloride. Severe corrosion is expected on articles electroplated in the presence of aluminum chloride. In the present investigation, the use of aluminum halides was avoided. Aluminum phosphate was employed in the system …

Interaction of Na, O₂, CO₂ and water on MnO(100): Modeling a complex mixed oxide system for thermochemical water splitting
… for thermochemical water splitting based on sodium and manganese oxides (Xu, Bhawe and Davis, PNAS, 2012). The key steps are thought to be hydrogen evolution from a Na₂CO₃/MnO mixture, and oxygen evolution by thermal reduction of solids formed by Na⁺ extraction from NaMnO₂. Our work is aimed …
