WebThe optical basicity addresses the ability of oxide glass in contributing the negative charges in the glass ma-trix. In other words it defines the electron donating power of the oxygen in the oxides glass. The theoretical opt-ical basicity can be calculated by the equation proposed by duffy and Ingram [23] WebOptical basicity was proposed by Duffy and Ingram [1,2] is used as a measure of acid- base properties of oxides and glasses. Dimitrov and Sakka [3] have estimated the optical …
WebFeb 26, 2015 · A new method (named as DASF: Derivation of absorption spectrum fitting) is proposed for the determination of optical band gap and the nature of optical transitions in semiconductors; this method only requires the measurement of the absorbance spectrum of the sample, avoiding any needs to film thickness or any other parameters. WebBasicity (in metallurgy), the ratio (in percent by weight) of basic and acidic oxides in iron ore materials (iron ore, sinter, and pellets), and also in blast-furnace and steel-smelting slag. Basicity defines the chemical composition and metallurgical properties of such materials.
