Abstract

A mechanically driven graphite fiber microbalance is used to investigate the wetting behavior of argon on graphite. We found evidence of complete wetting above the bulk triple point T₃ and incomplete wetting below. Below T₃ the thickness d of the saturated adsorbed film is found to obey the power law d ∝ (t)^x, with x=-1/3, in the reduced temperature range 10^-5<=(T₃ - T)/T₃<10^-2. Above T₃ the film thickness diverges as d ∝ [ln (P₀/P)]^x, with x=-1/3.
