The Periodic Element Guys present a 99.95% pure 0.5 grams plus melted platinum bead in sealed glass ampoule in labeled glass vial.
Platinum is used in jewelry, wire, to make crucibles and vessels for laboratory work, electrical contacts, thermocouples, for coating items that must be exposed to high temperatures for long periods of time or must resist corrosion, and in dentistry. Platinum-cobalt alloys have interesting magnetic properties. Platinum absorbs large amounts of hydrogen at room temperature, yielding it at red heat. The metal is often used as a catalyst. The platinum wire will glow red-hot in the vapor of methanol, where it acts as a catalyst, converting it to formaldehyde. Hydrogen and oxygen will explode in the presence of platinum.
