Ferrophosphorus 化学特性,用途語,生産方法
使用
In preventing thin sheets from sticking together when rolled and annealed in bundles.
定義
An alloy of iron and phosphorus used in the steel industry for adjustments of phosphorus content of special steels.
一般的な説明
A solid alloy of iron and phosphorus used in the steel industry (. Usually either 18% phosphorus or 25% phosphorus.
反応プロフィール
Ferrophosphorus, a less reactive metal alloy, is a reducing agent. Can react exothermically with oxidizing acids to form noxious gases. May catalyze polymerization and other reactions, particularly when finely divided. May react with halogenated hydrocarbons, sometimes forming explosive compounds Less reactive in bulk form (sheet, rod, or drop) than when finely divided. May form irritating vapors and toxic gases, such as phosphorus oxides or phosphoric acid when involved in fire.
健康ハザード
Exposure can cause irritation of eyes, nose and throat.
火災危険
Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as phosphorus oxides or phosporic acid, may be formed when involved in fire.
工業用途
This substance is an iron containing a high percentageof phosphorus, used for adding phosphorusto steels. Small amounts of phosphorusare used in open-hearth steels to make themfree-cutting, and phosphorus is also employedin tinplate steels to prevent the sheets fromsticking together in annealing. Ferrophosphorusis made by melting phosphate rock togetherwith the ore in making pig iron. There is alsoa master alloy, ferroselenium, for adding seleniumto steels, especially stainless steels, togive free-machining qualities.
