Titanium, Physical and Chemical Properties | SpringerLink
Physical Properties. Titanium is one of the most abundant metals in the Earth's crust, was discovered in 1791 but was produced on industrial scale only in the 1950s because of the difficulties in obtaining it in a pure form due to its reactivity. It is a light metal of high melting point and excellent corrosion resistance.

Barite Mineral | Uses and Properties
Physical Properties of Barite. Barite is generally easy to identify. It is one of just a few nonmetallic minerals with a specific gravity of four or higher. Combine that with its low Mohs hardness (2.5 to 3.5) and its three directions of right-angle cleavage, and the mineral can usually be reliably identified with just three observations.
