“…Wetting is expected to be affected by chemistry and temperature, but surface roughness and time of exposure are significant variables for refractories. Comeforo and Hursh 129 have measured contact angles between liquid glass and aluminosilicate refractories, and powerful effects of both are illustrated in Fig. 16.…”

A common theme over the past 100 years in refractories science and technology has been to generate a protective refractories layer in a high-temperature container, often by reaction of the refractory materials with the contents (glass, slag, or atmosphere). The history of refractories during the 20th century is used in this review to illustrate how techniques-such as slag splashing, in situ spinel generation in castables, magnesia dense layer formation in magnesiacarbon brick in steelmaking, clinker adhesion in cement kilns, and viscous boundary layer generation in glass tanks-have evolved to their present status.

“…A number of studies have evaluated the wettability of oxide ceramics by glasses and metals [52][53][54][55] and the wettability of nitride ceramics by molten metals [56][57][58][59]. Far fewer studies have examined the wettability of nitride ceramics by glasses [30,31,60].…”

The use of aluminum nitride (AIN) as a substrate and packaging material for microcircuit applications is of present interest due to its many advantageous physical properties. A limitation to the widespread use of AIN is the lack of an adequate metallization system. In this paper, the indirectbonded metallization of AIN will be reviewed-in particular, thick-film metallization, where the intermediate material is often a glass, and brazing, where the intermediate material is an active metal. Requirements which must be considered in producing successful metallizations include wetting of the substrate and the metal by the intermediate phase, and the reactivity between the intermediate phase and the substrate. In the case of thick-film metallization, these reactions can often be deleterious to the properties of the metal layer. In brazing, reaction between the active metal and the substrate is essential for achieving wetting of the ceramic surface by the molten braze and, thus, for producing high-strength joints. The reactions which occur in many of the systems considered can be predicted by examination of thermodynamic data.

“…[5][6][7][8][9][10][11][12][13][14][15] Wetting studies using SiO 2 have also been conducted, but not with liquid slag. [16][17][18] Many factors affect the contact angle, including the solubility of the two materials. Wetting studies based on the dissolution of two materials have been widely carried out regarding the system between liquid metals and solid metals or solid ceramics.…”

Wetting and Spreading Kinetics between Liquid CaO–SiO2 Slags and a Solid SiO2

Wetting and spreading phenomena between SiO 2 single crystal and CaO-SiO 2 slags with difference composition; SiO 2 saturated and non-saturated slags at 1 600°C were investigated by using the dispensed drop technique (DDT) with a high-speed camera (1 000 frames/s). The apparent contact angle and height of non-saturated slag were significantly smaller than those of saturated slag. The apparent radii of saturated and non-saturated slags were significantly different after 0.01 s. The change in the apparent volume of the slags was analyzed by using a spherical cap model. The apparent volume of the saturated slag was constant, but that of the non-saturated slag decreased because of film type spreading. After quenching, the film type spreading was verified, and a dissolution reaction occurred in the non-saturated slag, whereas no such phenomena were observed in the saturated slag. For the saturated slag, the spreading kinetics fit well with the non-reactive viscous model suggested by a previous study. However, nonsaturated slag could not be applied to spreading kinetics due to the film type spreading.
