硒化锶 制备方法及用途

制备方法

1.将硒酸锶SrSeO4在氢气流中还原,温度为600℃,可得到纯白色的硒化锶结晶。2.亚硒酸锶在较高温度下用氨还原。亚硒酸锶是由溶于水的纯的SeO2与硝酸锶热溶液反应,加氨水中和后有亚硒酸锶沉淀析出,过滤,用水洗涤至不含硝酸盐(约洗6次)为止。在200℃下干燥。将亚硒酸锶在NH3气流中于860℃还原2~3h,可得硒化锶。

  Most important symptoms and effects, both acute and delayed
    Acute selenium poisoning produces central nervous system effects, which include nervousness,
    convulsions, and drowsiness. Other signs of intoxication can include skin eruptions, lassitude,
    gastrointestinal distress, teeth that are discolored or decayed, odorous ("garlic") breath, and partial loss of
    hair and nails. Chronic exposure by inhalation can produce symptoms that include pallor, coating of the
    tongue, anemia, irritation of the mucosa, lumbar pain, liver and spleen damage, as well as any of the other
    previously mentioned symptoms. Chronic contact with selenium compounds may cause garlic odor of
    breath and sweat, dermatitis, and moderate emotional instability., To the best of our knowledge, the

  Respiratory protection
    Where risk assessment shows air-purifying respirators are appropriate use a full-face particle
    respirator type N99 (US) or type P2 (EN 143) respirator cartridges as a backup to engineering
    controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use
    respirators and components tested and approved under appropriate government standards such
