I-About Rhodium

Rhodium is ultra-rare, silvery-white, hard, and corrosion-resistant. It has the highest reflectance of any metal and is one of the most expensive metals in the world.

Iinkqubo

Iinkqubo zokutshintsha i-catalyst, ukuhombisa iimpahla, i-laboratory crucibles, kunye neezixhobo ezibonakalayo.

Inyathelo 1:

Ii-80% ze-rhodium yehlabathi isetyenziswa kwii-catalytic converters, kwaye ibiza kakhulu kunegolide okanye iplatinum.
