B-1 type insulating firebricks are made from high refractory clays with graduated addtions of alumina for the higher temprature products,and a carefully graded organic filler,which burns out during manufaturing to give a controlled,uniformed lacuna structure.Each brick machined to precise size on all six faces.The maxmium continue use tempreture depends on application.(900)

recommended for use as primary hot face refractory lining or as back-up insulation behind other refractory in furnace,kins,flues,refining vessels,heaters,regenerators,gas producers and main soaking pits,annealing furnace,catalyst case and similar high temprature industrial equipment.
