Marietta Magnesia Specialties LLC, a subsidiary of Martin
Marietta Materials, is a leading U.S. producer of magnesia-based
chemical products used in a variety of industrial, chemical
and environmental applications.
Chemical-grade magnesia is marketed as a process additive,
used as raw material for products we use every day, such as
ceramics, paper and sugar. Magnesia Specialties markets agricultural
grades of magnesium oxide for use in mineral premixes and
animal feed, environmentally friendly air and water treatments
and a new flame-retardant product.
In addition, at its Woodville, Ohio, facility, dolomitic
lime is produced. A significant amount of this product is
sold to the steel industry as a fluxing agent to help purify
steel and extend refractory lining life.
