    1966-7-1 · The investigation has shown that the wetting of refractory compounds by metals is directly linked with the character of their chemical reaction, as well as with the direction of preferential transport of elements, from the melt to the refractory support or vice versa. The wetting of a support material by a melt can be controlled by means of additions to one of the contacting materials…
