非氧化物玻璃形成能力的化学键方法 总被引:4,自引:0,他引:4
本文采用化学键方法对卤化物及硫卤玻璃的化学键特性进行了探讨。所有的玻璃组成均可分为3类:硬质玻璃组分,如氟化物;软质玻璃组分,如溴化物、碘化物、硫系化物;中间玻璃组分,如氯化物。具有高正电荷,小离子半径的阳离子适合形成硬质玻璃,而那些低氧化态、大离子半径的阳离子则适合于形成软质玻璃。导致硬质玻璃组分与软质玻璃组分具有不同“赠-受”键的原因是这两种玻璃组分具有不同的聚合机理,玻璃结构中簇间化学键力平衡和热能(温度)平衡也得到了讨论。 相似文献

The volatilities of simulated, high-level nuclear waste glasses have been measured using thermogravimetric analysis (TGA). These volatilities were measured in the region of the glass transition temperature ( T g ) of the waste glasses, which is between 450° and 500°C. These data were obtained because the Waste Acceptance Preliminary Specifications require that no foreign materials be released into the canistered waste form upon heating of the canister to this glass transition temperature. In fact, all of the waste glass samples studied actually exhibited a net weight gain upon heating. This weight gain was shown to be due to oxygen uptake through oxidation of FeO. Powdered glass samples did show a small weight loss which was smaller in magnitude than the weight gain and was associated with water desorption. No true volatility was detected to the level of sensitivity (0.01 wt%) of the TGA instrument. This converts to a sensitivity of 330 μ g/m2 of glass surface and a corresponding minimum value of 41 mg of volatiles for each Defense Waste Processing Facility conistered waste form. TGA experiments carried out at higher temperatures (800°C) revealed that organic concentrations in the waste glasses are less than 0.01 wt%. Thus, these results demonstrate that the Defense Waste Processing Facility will be able to comply with the Waste Acceptance Preliminary Specifications on the exclusion of foreign materials from the canistered waste forms, after exposure to T g . 相似文献
