Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
This article from the 1928–1936 Soviet medical encyclopedia details the chemical and physical properties of titanium, including its atomic weight, melting point, and occurrence in nature. It specifically describes the medical applications of its salts, particularly the use of titanium sulfate and titanium oxide in treating tuberculosis, skin conditions, and eye diseases.
Encyclopedia entry (1928–1936)
TITAN, Titanum, chemical symbol Ti, occupies the 22nd place in the periodic system (Group IV). A homologue of silicon (Group IV). Atomic weight 47.90. T. has a metallic luster, is brittle but very hard. Specific gravity 4.8. Melting point 1800–1850°. T., despite its large occurrence in nature, is obtained in small quantities. In medicine the following salts of T. are applied: 1) Sulfuric T., internally in tuberculosis, externally in scrofulous skin lesions, conjunctivitis, keratitis, lupus in solutions of 0.05–0.1 in 100.0 water. 2) Oxide of T. (Titan, oxyd.), TiO2, titanium white, in ointments and powders in all respects replaces oxide of zinc. Oxide of T. can be applied in the form of a 10–20% ointment on a lanolin-vaseline basis in eczema, sycosis (non-parasitic), in skin diseases with itching and completely replaces oxide of zinc; it is also applied with the addition of 5% salicylic or boracic T.
