What are 70 percent alumina fire bricks?
High alumina fire bricks and refractory mortars build and repair hot linings in furnaces, kilns and boilers. More alumina generally means better resistance to high temperature and slag.
Mortar must match the brick. Therefore, use the refractory mortar or castable the maker recommends for the lining.
