It has excellent resistance to corrosion, is stable at high temperatures and has stable electrical properties. which country was the first to discover it? UNANSWERABLE do people invest in it? Yes, as it finds use in jewellery, usually as a 90–95% alloy, due to its inertness. what makes it more malleable? By alloying it with gold, dissolving the alloy in hot "aqua regia", precipitating the platinum with ammonium chloride, igniting the ammonium chloroplatinate, and hammering the resulting finely divided platinum to make it cohere.

Platinum [SEP] Health problems
According to the Centers for Disease Control and Prevention, short-term exposure to platinum salts may cause irritation of the eyes, nose, and throat, and long-term exposure may cause both respiratory and skin allergies. The current OSHA standard is 2 micrograms per cubic meter of air averaged over an 8-hour work shift. The National Institute for Occupational Safety and Health has set a recommended exposure limit (REL) for platinum as 1 mg/m over an 8-hour workday. As platinum is a catalyst in the manufacture of the silicone rubber and gel components of several types of medical implants (breast implants, joint replacement prosthetics, artificial lumbar discs, vascular access ports, etc.), the possibility that platinum could enter the body and cause adverse effects has merited study.
