Химические свойства
Aluminum fluoride, AlF3, is an anhydrous crystalline powder with a melting point of 1291 "C. Aluminum fluoride (hydrated), AlF3·31/2H20, is a white crystalline powder that is insoluble in water.
Использование
Aluminum fluoride is used to produce lowmelting
aluminum metal, as a flux in ceramic glazes and white enamels, and as a catalyst in
chemical reactions.
Общее описание
Odorless white powder or granules. Denser than water. Solubility in water at 25°C equals 0.559 g / 100 mL.
Реакции воздуха и воды
Slightly soluble in water
Профиль реактивности
Aluminum fluoride when heated to sublimation condition, emits toxic fumes of fluoride [USCG, 1999].
Опасность
Strong irritant to tissue.
Угроза здоровью
ACUTE: respiratory irritation; possible nose bleeding or vomiting; CHRONIC: aggravates bronchitis/asthma; increased bone density.
Пожароопасность
Special Hazards of Combustion Products: When heated to sublimation condition, emits toxic fumes of fluoride
Профиль безопасности
A poison by ingestion. Moderately toxic by subcutaneous route. A severe eye irritant. Violently impact-sensitive when in contact with Na and K. When heated to decomposition it emits toxic fumes of F-. See also FLUORIDES and ALUMINUM COMPOUNDS.
Возможный контакт
Used as component of electrolyte from which aluminum metal is produced; in the manufacture of ceramics, enamels, aluminum silicate; as flux in metallurgy; as a fermentation inhibitor
