• 説明

  Strontium Oxide, SrO, is a metal oxide usually produced by the reaction of strontium with oxygen. It can also be prepared by the decomposition of heated strontium carbonate, hydroxide, or nitrate and is used in manufacturing other strontium salts, in pigments, soaps and greases, and as a drying agent. It is commonly used in the glass, ceramics, and electronic industries and has other specific uses, such as fuel cells and sputtering target material. If burn strontium under general conditions with air, strontium oxide and strontium nitride will form. Strontium oxide was once required by law as the material used on old TV face-plates to block harmful X-ray emissions. BaO and SrO were reported for the transesterification of palm oil for the production of biodiesel. The reaction was conducted under ultrasound conditions to ensure the effective production of biodiesel.

• 化学的特性

  white to grayish white; reacts with water, forming Sr(OH)2, with evolution of heat; enthalpy of fusion 75.00kJ/mol [MER06] [CRC10]

• 物理的性質

  Strontium oxide or strontia, SrO, is formed when Sr metal reacts with oxygen:
  2Sr＋ O2→2SrO
  Burning strontium in air results in a mixture of strontium oxide and strontium nitride. It also forms from the decomposition of strontium carbonate SrCO3. It is a strongly basic oxide. It reacts with moisture forming the hydroxide and with carbon dioxide in the air to form the carbonate.

• 使用

  SrO is also used in medicine, pyrotechnics, pigments, greases, soaps, and as a chemical intermediate. It is also produced as high-purity strontium oxide rotatable sputtering targets with the highest possible density and smallest possible average grain sizes for use in semiconductor, photovoltaic, and coating applications by chemical vapor deposition and physical vapor deposition and optical applications.One of the reasons why rare metals are restrained from wide use in production is their high cost.
