Answer:

Hardness, non-molecularity, high melting point.

Explanation:

Boron nitride is isostructural and isoelectronic with carbon graphite. It has many crystalline modifications. One form is used as a lubricant, precisely as you would use carbon graphite. When pure the stuff is white; as a lubricant it goes dark grey very rapidly.
