Osmium [SEP] Physical properties
Osmium has a blue-gray tint and is the densest stable element; it is approximately twice as dense as lead and slightly denser than iridium. Calculations of density from the X-ray diffraction data may produce the most reliable data for these elements, giving a value of for osmium, slightly denser than the of iridium; both metals are nearly 23 times as dense as water, and times as dense as gold. Osmium is a hard but brittle metal that remains lustrous even at high temperatures. It has a very low compressibility. Correspondingly, its bulk modulus is extremely high, reported between and , which rivals that of diamond ().
