Platinum is one of the nine precious metals found on the periodic table. It has a high melting point of 1,772°C and a density of 21.4 grams per cubic centimeter. When heated to around 1,747°C, its vapor pressure reaches about 10⁻⁴ Torr. This lustrous, silvery-white metal closely resembles palladium in appearance. Known for its density, malleability, ductility, and excellent resistance to corrosion in air, platinum is widely used across various industries. Its most well-known commercial application is in automotive catalytic converters. Additionally, platinum is evaporated in vacuum conditions for producing components in semiconductors, fuel cells, and batteries. It is also employed as a thin film in optical coatings. Beyond industry, platinum is often seen in jewelry and scientific instruments.

I received the platinum target for my magnetron sputtering system about a month ago. The tolerance (±0.005") was spot-on, and it fit perfectly into my holder without any modifications. I processed films at 1850-1900°F under vacuum, and the thin films showed uniform thickness and excellent adhesion, thanks to the high purity (99.99%) and density of the target.
Got the 2" × 0.25" platinum sputter target last week. Packaging was solid—double wrapped with foam and plastic sealed, so no damage. The metal is super dense and clean, matches the 99.99% purity claim. Used it for thin film deposition at around 1800°F, adhesion so far is great. Just a heads-up, edges were a bit sharp, so be cautious when unpacking. Overall, very satisfied for the price and quality.
So much high quality for such a cheap price. Came exactly as described and good quality.
