Metallic crucibles
nitric acid, nitrate and potassium permanganate. Good resistance to concentrated alkaline
solutions. Average resistance to acetic acid, hydrogen sulphide diluted, phosphoric
low concentration, and solutions of sulphites, boric acid, organic acids and
bromides.
NICKEL unalterable in the air and stainless up to temperatures of 500 °C, good resistance
to molten alkali and seawater.
Excellent performance in the presence of wet chlorine or hydrochloric acid gas up to
500 °C. Slowly attacked by organic acids, hydrochloric and sulfuric acids.
Low resistance to diluted nitric acid.
THE ZIRCONIUM unalterable in the air and clean, resistant up to 550 °C in an oxidizing
atmosphere at 1500 °C in inert gas (argon or nitrogen), in many cases to replace
platinum crucibles in all melting and in particular the sodium peroxide and
carbonates. About 100 melting per crucible, making them very economical with
reference to the others, either porcelain crucibles, steel or nickel. Resistant to most
alkali solvents (Na, K, Li), carbonates, hydroxides, peroxides, borates, nitrates, chlorides,
some fluorides and sulfuric acid up to 75% concentrate.
Hydrofluoric acid attacks it.
STAINLESS STEEL is usable at temperatures from -180 °C to +500 °C. Resistant to
nitric acid, nitrate and potassium permanganate. Good resistance to concentrated alkaline
solutions. Average resistance to acetic acid, hydrogen sulphide diluted, phosphoric
low concentration, and solutions of sulphites, boric acid, organic acids and
bromides.
NICKEL unalterable in the air and stainless up to temperatures of 500 °C, good resistance
