Wetting and Spreading Kinetics between Liquid CaO–SiO<sub>2</sub> Slags and a Solid SiO<sub>2</sub>

چکیده
Wetting and spreading phenomena between SiO2 single crystal CaO–SiO2 slags with difference composition; saturated non-saturated at 1600°C were investigated by using the dispensed drop technique (DDT) a high-speed camera (1000 frames/s). The apparent contact angle height of slag significantly smaller than those slag. radii different after 0.01 s. change in volume was analyzed spherical cap model. constant, but that decreased because film type spreading. After quenching, verified, dissolution reaction occurred slag, whereas no such observed For kinetics fit well non-reactive viscous model suggested previous study. However, could not be applied to due

Wetting and spreading
Wetting phenomena are ubiquitous in nature and technology. A solid substrate exposed to the environment is almost invariably covered by a layer of fluid material. In this review, the surface forces that lead to wetting are considered, and the equilibrium surface coverage of a substrate in contact with a drop of liquid. Depending on the nature of the surface forces involved, different scenarios ...

the present study was an attempt to conduct a contrastive analysis between general english (ge) and english for specific purposes (esp) texts in terms of cohesion and cohesive devices. to this end, thirty texts from different esp and ge textbooks were randomly selected. then they were analyzed manually to find the frequency of cohesive devices. cohesive devices include reference, substitution, ...

the relation between bilingualism and translation: a case study of turkish bilingual and persian monolingual translation students
translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...
