解説硫酸コバルトとは、コバルトの硫酸塩の無機化合物です。 硫酸コバルトには、硫酸コバルト (II) と硫酸コバルト (III) の2種類が存在します。硫酸コバルト (II) には、無水物、一水和物、七水和物が知られています。 硫酸コバルト (II) の七水和物は、濃紅色の柱状結晶です。別名、赤バン (英: bieberite) とも呼ばれています。日本で赤バンは、奈良県の堂ヶ谷鉱山や山梨県の鳳来鉱山などで確認されています。

用途メッキ添加剤、触媒

用途磁性体用、金属石けん?顔料原料、塗料?インキ乾燥剤、防錆材原料、飼料添加物、メッキ薬、触媒

使用Usual source of water-soluble cobalt since it is the most economical and it shows less tendency to deliquesc or dehydrate than the chloride or nitrate. Used in storage batteries; in Co-electroplating baths; as drier for lithographic inks, varnishes; in ceramics, enamels, glazes to prevent discoloring; in Co pigments for decorating porcelain.

一般的な説明Pink to red monoclinic prismatic crystals or red granular solid. Odorless. Becomes anhydrous at 788°F.

使用用途硫酸コバルト (II) は、コバルトめっきや磁性材料、陶磁器の釉薬、コバルト塩の製造などに用いることが可能です。また、防錆材原料や各種や、ぺイント・インキの乾燥剤、や陶磁器の彩色用顔料、触媒、金属せっけん、不可視インク原料など、幅広い用途が挙げられます。 硫酸コバルト (II) は、医薬品分野では、貧血用薬にミネラル成分として配合されています。さらに、農業分野においても、同様の目的で、飼料添加物として使用可能です。 それに対して硫酸コバルト (III) は、強い酸化剤として使用されています。

調製方法 · 1 件

純化方法Crystallise it three times from conductivity water (1.3mL/g) between 100o and 0o depending on which hydrate is required. The heptahydrate crystallises below 44o and is efflorescent with m 97o . Between 44o and 70o the monoclinic hexahydrate CoSO4.6H2O m 41.5o is formed, and above 70o the monohydrate CoSO4.H2O m 71o is obtained. The pale reddish or lavender-coloured anhydrous salt is obtained by heating the hydrate above 250o, boiling with conc H2SO4 or heating with (NH4)2SO4).

化学的性質

化学的特性Cobalt sulphate appears as pink or red crystals. It is stable, non-flammable, and hygroscopic and undergoes dehydration at 41°C and 71°C.

Reactive GroupSalts, Acidic
EC ClassificationSymbol: T, N; R: 49-22-42/43-50/53; S: (2)-22-53-45-60-61; Note: E
Reactivity Profile · 1 件

Acidic salts, such as COBALT SULFATE HEPTAHYDRATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

Chemical DangersDecomposes above 100 °C . This produces toxic fumes of sulfur oxides. The dust reacts with strong oxidants. This generates fire and explosion hazard.
Air and Water ReactionsWater soluble. The resulting solution is acidic.
