Boron nitride components engineered by Precision Ceramics USA are ideal for high temperature runner systems in hot metal casting |
Boron Nitride Industrial Powders are pure, white, ceramic materials with a hexagonal crystal structure similar to graphite.
Commonly known as 'white graphite', hexagonal BN (hBN) is a man-made ceramic produced by reacting boric acid or boron oxide and nitrogen at temperatures above 1600°C. The resulting product is a slippery white powder that has excellent high temperature stability (oxidation resistant up to 850°C) and lubricating properties.
Boron nitride is white
(clean appearance), non-toxic and a non-conductor of electricity,
and is an excellent substitute for other commonly used lubricants
in metals processing such as graphite, molybdenum disulfide, and
organic waxes and oils. In most cases, boron nitride substantially
improves the efficiency of these applications.
Boron Nitride Industrial
Powder is supplied in coarse and fine mesh sizes in standard and
high purity grades.
There are many
Boron Nitride Industrial Powder grades from which to select.
