americium dioxide造句

例句与造句

1. Americium-aluminium alloys can be formed by melting americium dioxide with aluminium and an additional fluxing agent.
2. First, americium ( 241 Am ) nitrate solution was coated on a platinum foil, the solution was evaporated and the residue converted by annealing to americium dioxide ( AmO 2 ).
3. Americium is the only synthetic element to have found its way into the household, where the most common type of smoke detector uses 241 Am in the form of americium dioxide as its source of ionizing radiation.
4. Whereas the Am 4 + ions are unstable in solutions and readily convert to Am 3 +, the + 4 oxidation state occurs well in solids, such as americium dioxide ( AmO 2 ) and americium ( IV ) fluoride ( AmF 4 ).
5. Smoke detectors use a very small quantity of 241 Am ( about 0.29 micrograms per smoke detector ) in the form of americium dioxide . 241 Am is used as it emits alpha particles which ionise the air in the detector's ionization chamber.
6. It's difficult to find americium dioxide in a sentence. 用americium dioxide造句挺难的
7. Synthesis of americium dioxide involves precipitating a solution of americium in hydrochloric acid ( HCl ) solution as described by the Oak Ridge National Laboratory The demand for americium dioxide stems from the difficulty of storing the element americium as a liquid in the hydrochloric acid solution because the alpha radiation and hydrochloric acid decomposes storage containers over time.

9. The americium oxalate is then added to a platinum boat to undergo calcination . The americium oxalate precipitate is dried in a furnace and will begin to decompose at 350 癈 . When decomposition begins to occur, the oxalate will turn into the desired black Americium dioxide; to ensure no oxalate remains in the newly forming dioxide, the oven temperature is increased and held at 800 癈 then slowly allowed to cool to room temperature.
