2002 NAICS Definitions
327125 Nonclay Refractory Manufacturing
This U.S. industry comprises establishments primarily engaged in manufacturing nonclay refractory, mortar, brick, block, tile, and fabricated nonclay refractories such as graphite, magnesite, silica, or alumina crucibles. A refractory is a material that will retain its shape and chemical identity when subjected to high temperatures and is used in applications that require extreme resistance to heat, such as furnace linings.
Cross-References. Establishments primarily engaged in manufacturing clay refractories are classified in U.S. Industry 327124, Clay Refractory Manufacturing.
