Product description
The fuming
sulfuric acid (containing 15% SO3) is more severely corroded than
concentrated sulfuric acid, immersed in the solution at 130 ° C for 1
year and the surface is etched to a thickness of 15.6 mm. Tantalum
is also corroded by phosphoric acid at high temperatures, but the
reaction typically takes place above 150 degrees Celsius, immersed for 1
year in 85% phosphoric acid at 250 degrees, and the surface is etched
by 20 mm. In addition, tantalum is contaminated with hydrofluoric acid
and nitric acid The mixed acid can quickly dissolve, can also be dissolved in hydrofluoric acid.
