The slag test showed that β-Sialon bonded MgAION has good slag resistance. The slag corrosion mechanism is as:β-Sialon and MgAION dissolve in slag and crystallized out acerous Sialon and spinel with near sto-icheome-tric composition, and slag penetrated into the body of sample.

通过对β-Sialon复合MsAION材料的抗渣及抗钢水侵蚀性能的研究发现，该材料抗渣侵蚀性能较好，侵蚀机理为β-Sialon与MgAION溶解于渣中并析出针状Sialon和近化学计量的镁铝尖晶石，同时渣向材料内部渗透。

In the condition of keeping F、 K、Na content fixed, To improve slag structure and raise slag melting point and viscosity, MgO content is raised and TiO〓 is added. the main content is as follows:(1) Keeping CaO/SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature goes up 106℃, the viscosity goe down at bigger than 1425℃, but difference is little; keeping /SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature rises 87℃, the viscosity rises too; adding TiO〓 to 5%, the free running temperature goes up 98℃, the viscosity rise a little.(2) Powder crystal x ray diffraction and microscopic analysis shows: increasing MgO content, the cuspidine will decreace or even disappear, the monticellite goes up with MgO content rising, keeping /SiO〓 fixed, Akermanite content goes up, for high melting point minerals appear or go up, the free running temperature of the slag bearing F is raised; Adding TiO〓, high melting point mineral—Perovskite forms, it can making other minerals'crystalling fast, it is the reason that TiO〓 raises the free running temperature of the slag bearing F.
