Chinese Refractory raw material resources are abundant, which are suitable for the production of various grades of insulating firebrick. Limiting temperature of use range from 900℃ to 1650℃.Each grade of insulating firebrick is formulated to meet specific thermal and physical requirements.

Top grade insulating firebrick are made from high-purity refractory clays, with graduated additions of alumina for the higher temperature products, and a carefully graded organic filler, which burns out during manufacture to give a controlled, uniform lacuna structure. Each brick machined to precise size on all six faces. The maximum continue use temperature depends on application.
