About Molybdenum
Molybdenum has the sixth-highest melting point of any element. It is an essential trace element in biology, found in certain enzymes. It is primarily used in high-strength steel alloys.
Gebruiks & Programme
High-strength steel alloys, catalysts, lubricants (MoS2), missile and aircraft parts, and fertilizers.
Fun Fact
Molybdenum's name was confused for centuries with lead and graphite because they all left similar dark marks on paper.
