Abstract:

Using zircon billet as aggregate，zircon powder as powder and aluminum dihydrogen phosphate liquid as binding component，this paper studied how different amount of micro zircon powder as admixture affects the performance of zircon ramming mass.With the help of scanning electron microscope，this paper also found the performance of the material under high temperature was  improved as zircon powder amount was increased.The best case scenario occured with addition of 5% zircon powder to the mass.Micro level zircon powder will form a kind of heterogeneous plate-shape ceramic bond,improving mechanics performance of the material to a great extent.
