<p><b>New page</b></p><div>'''Osmium tetroxide''' (also known as '''osmium(VIII) oxide''') is a chemical compound with the formula OsO<sub>4</sub>. The compound is noteworthy for its many uses, despite the rarity of osmium. It also has a number of interesting properties, some of which have important implications for its safety and handling.<br />
<br />
==Properties==<br />
Osmium tetroxide is a volatile, crystalline solid that sublimes at room temperature. It has a strong, unpleasant smell. The compound is highly toxic and can cause severe burns. It is also a powerful oxidizing agent.<br />
<br />
==Preparation==<br />
Osmium tetroxide can be formed by the direct combination of osmium and oxygen. It can also be produced by the oxidation of osmium with nitric acid or by the action of hot concentrated sulfuric acid on an osmium salt.<br />
<br />
==Uses==<br />
Osmium tetroxide has many uses. It is used in microscopy as a stain for lipids and in organic synthesis as an oxidizing agent. It is also used in the preparation of other osmium compounds.<br />
<br />
==Safety==<br />
Due to its high toxicity and volatility, osmium tetroxide should be handled with care. It can cause severe burns and eye damage, and may be fatal if inhaled. Appropriate safety measures should be taken when handling this compound.<br />
