Evaluating Plasma Torches as a Low‐Decarburization Preheating Method for MgO–C Refractory Linings

open access: yessteel research international, EarlyView.
This study evaluates direct current (DC) plasma torches using nitrogen as an alternative preheating method for magnesia‐carbon (MgO–C) refractory‐lined ladles. Full‐scale trials at 0.7 and 1.5 MW are compared to conventional gas burner. Plasma‐heated samples show lower decarburization and improved surface integrity due to partial sintering and reduced ...

Between the Sheets: CH3SO3H Molecules Intercalating B2O3 Layers

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The intercalation compound B6O9·CH3SO3H can be seen as the stabilization of a new B2O3 modification by methanesulfonic acid. The structure elucidation was performed by X‐ray diffraction and solid‐state NMR measurements. The reaction of boric acid and methanesulfonic acid yielded single crystals of B6O9·CH3SO3H (monoclinic, I2/a, Z = 8, a = 873.19(3), b
