Np. Artyunina et al., CORROSION-RESISTANCE OF POROUS BINARY TANTALUM AND TITANIUM CARBIDES OF VARIOUS COMPOSITION, Russian journal of applied chemistry, 66(7), 1993, pp. 1162-1165
Resistance of porous binary tantalum and titanium carbides in solution
s of mineral acids and their mixtures, of several organic acids, and o
f ammonium and potassium hydroxide was studied. It has been shown that
as the content of tantalum in a material increases its resistance in
solutions of oxidizing acids is improved, but it is reduced in solutio
ns of sulfuric and hydrofluoric acids and also in solutions of potassi
um hydroxide.
