Optimization of Intensified Silicon Deoxidation
steel research international, 2012AbstractFor demanding wire applications steel cleanliness should be very high and the inclusions inevitably found in steel should be harmless. This means strict control of inclusions' size, quantity, and composition, pursuing deformable inclusions in rolling conditions. Primary inclusions are formed during steel treatment in the ladle.

Deoxidation and subsequent densification of sintered titanium by Ca deoxidizer
Metals and Materials International, 2016In this study, a sintering process involving simultaneous deoxidation and sintering was developed, using the vapor of a deoxidizer (Ca) to produce low-oxygen, high-density titanium. Compared to a series of reference titanium powder samples, the bodies sintered with Ca exposure had an ∼1,400 ppm lower oxygen content, resulting in an ∼2% increase in ...

Electrochemical deoxidation of titanium
Metallurgical Transactions B, 1993Removal of oxygen in titanium using an electrochemical technique was examined at temperatures around 1223 K with the purpose of obtaining nearly oxygen-free titanium. Titanium and carbon electrodes, immersed in molten CaCl2, served as cathode and anode, respectively, with an external DC source. CaCl2 was employed to produce the deoxidant calcium and to

Copper deoxidizing by elements such as phosphorus and lithium is common in industry, but when copper is deoxidized with phosphorus, leaving a residual phosphorus greater than 0.01%, electrical conductivity is rapidly reduced. Copper deoxidizing by lithium in industry is not common because of the high cost.

Deoxidation of Titanium Using Mg as Deoxidant in MgCl2-YCl3 Flux
Metallurgical and Materials Transactions B, 2019To reduce the oxygen level in titanium (Ti) to less than 1000 mass ppm O, using magnesium as the deoxidant at 1300 K (1027 °C), the activity of the deoxidation product (MgO), i.e., aMgO, in the system must be reduced to less than 0.04, from a thermodynamic viewpoint.

Surfaces of oxides used as catalysts at low temperatures (below about ¼ of the melting point in K) contain various defects (steps, vacancies, interstitials, etc.) which may be privileged sites for the catalytic reaction (Gravelle and Teichner, 1969). Satisfactory correlations may be then obtained between a defect surface structure of the catalyst and ...
