Research on Mechanical Property of Single Panel Fire-Resistant Glass with Cs+ Ion and Rb+ Ion Exchange

The effect of Cs+ ion and Rb+ ion in the molten salt of different proportion on the single panel fire-resistant glass is discussed in this paper. The single panel fire-resistant glass was prepared by the method of ion-exchange, with proper amount of additives and adding KNO3 and CsNO3 , KNO3 and RbNO3 as the main part of molten salt. The proportion of the molten salt was changed separately, a contrast test was performed to measure the flexure strength. The results indicated that the flexure strength of the single panel fire-resistant glass increased firstly and then stabilized as the ratios of w(CsNO3)/w(KNO3) and w(CsNO3)/w(RbNO3) increased respectively. With the ratio of w(CsNO3)/w(KNO3) =1.5%, the mechanical property of the single panel fire-resistant glass was proper and the maximum flexure strength was 274 MPa. In the case of RbNO3, the flexure strength of single panel fire-resistant was 244 MPa with the ratio of w(CsNO3)/w(KNO3) = 0.3%. According to the research, it is found that the method of ion-exchange of Cs+ and Rb+ into plain glass to prepare single panel fire-resistant glass is feasible, the sample melted under the condition of 1 hour and 780 without any trace of thermal explosion.

ABSTRACTThe advantage of self-reinforced silicon nitride is the in-situ control of the microstructure. This control is provided in large degree by the chemistry of glassy phase which can be adjusted to tailor the morphology of silicon nitride grains as well as the matrix - reinforcement interface. The presence of high aspect ratio silicon nitride grains is necessary but not sufficient condition to produce materials with optimum properties. For maximum flexure strength and fracture toughness an optimized glass matrix is required.

Niobium Oxides

Dion-Jacobson type layered perovskite niobium oxides KCa2Nb3O10 and KSr2Nb3O10 were prepared via molten salt method, and the potassium cations were exchanged by protons using nitric acid. Different degrees of proton exchange were adjusted, and the dependence of photocatalytic activity for hydrogen evolution on proton exchange was investigated. Moreover, proton exchange leads to different amounts of water incorporated into the interlayer spaces, also influencing photocatalytic performance significantly. Decoupling water intercalation and proton exchange, the photocatalytic activity of proton exchanged KCa2Nb3O10 and KSr2Nb3O10 can be revealed and tailored for maximum activity.

Abstract For the analysis of the isotopic composition of environmental samples, including transuranic materials there are many methods that exist. This paper describes the development of a high throughput method, which involves dissolving a soil into an aqueous matrix, producing a homogenous mixture, and separating radionuclides to enable the identification of specific isotopes. A standard method was modified via changes in oxidation, chemical exchange, decomposition, or rearrangements to form constituents that are more soluble in acidic aqueous solutions. To accomplish this, a molten-salt fusion, dissolution in dilutes nitric or hydrochloric acids, with subsequent separation using ion exchange, direct deposition, and counting by alpha-spectrometry was used. This method is ideal for silicate samples, but can be modified to accommodate more complex soil samples.
