In general, furnace lining materials and structures are increasingly focused on their energy saving properties in addition to their high temperature resistance. Energy saving apart from a reasonable heating system and control system, the following requirements are mainly made for the furnace lining materials: (1) the heat insulation performance is good, and heat can be effectively prevented from diffusing outside the furnace; (2) the heat storage amount is small, the energy consumption required by heating the furnace lining is low, and the material with small heat storage amount has very remarkable energy-saving effect particularly for batch furnaces. It has been found that reducing the density of the material meets the above-mentioned energy saving requirements, and therefore a wide variety of lightweight materials have been produced for use as furnace lining materials, such as the more common foam lightweight bricks, hollow sphere lightweight bricks, ceramic fiber products, and the like. Among the light materials, the energy-saving effect of ceramic fiber materials and products is the best, so that most kilns with lower use temperature adopt ceramic fiber products as lining materials; however, ceramic fiber materials also have a number of fatal disadvantages: (1) the strength is very low, the furnace wall can not bear load, and the furnace wall is easy to damage; (2) the surface is easy to melt and corrode and easy to pulverize after bearing high temperature for a long time; (3) the corrosion resistance is poor, and the corrosive gas cannot be contacted; (4) are expensive, and particularly expensive to sell for higher temperature ceramic fibers.
