Contact Angle of Zinc on Some Ceramic Materials and Metals.
J Testing and Mat 1974 Jan; 2(1):40-43
Measurements were made of the contact angle of molten zinc drops on 15 ceramic materials and 4 metals in high-purity helium and carbon monoxide atmospheres. Zinc of 99.9999-percent purity did not wet the oxide materials, glass-type coatings, or graphite; all contact angles were greater than 90 degrees at 500 deg. to 700 deg. C in helium and 500 deg. to 800 deg. C in carbon monoxide. Materials tested that were most resistant to wetting by zinc were zno sinter, glazed fireclay, graphite, and mullite.
