Abstract

A fireproof material containing aluminum-silicon alloy. the material contains 60-75% corumdum aggregate, 10-20% fine corumdum powder, 5-15% fine powder of aluminum-silicon alloy, 1.5-5% clay, 5-12% aluminum oxide. The fine powder of aluminum-silicon alloy is formed by melting or sintering metallic aluminum and metallic silicon. Due to introduction of fine powder of aluminum-silicon alloy, in producing corundum brick, the coupling phase could be quickly formed, the coupling strength between the coupling phase and brown corumdum aggregate will be improved. Compared the burning temperature of 1500degree C in the conventional process, the burning temperature of the invention is reduced to about 1430degree C , which improves the capacity of resisting rupture and high temperature.

Description

technical field [0001] The invention relates to a sialon bonded refractory material. Background technique [0002] G. Ervin first discovered the practicability of SiC-AlN solid solution in 1970 and applied for a patent for the first time. [0003] In the early 1970s, British and Japanese researchers discovered that Al 2 o 3 Added to Si 3 N 4 Hot pressing in Si 3 N 4 Solid solution of Al in the lattice 2 o 3 up to 60-70% (weight), and found that Si in this solid solution 3 N 4 The silicon atoms and N atoms in the system are replaced by Al atoms and oxygen atoms respectively, forming a new Si-Al-O-N system, which is named Sialon in order of their first letters. [0004] Jacques.P.R. proposed a method of adding 23-90% of the metal silicon powder with a particle size of less than 150 μm, and 9-62% of the particle size with a particle size of less than 20 μm in high melting point raw materials such as corundum, mullite, zircon mullite, and magnesia. sintered alumina po...
