The Effect of Addition of the Spinel or Spinel with TiO_2 on the Performance of Magnesia Material

In this paper,by taking the fused magnesia,fused magnesium aluminate spinel and fused spinel with TiO2 as raw materials,we studied the effect of adding 15% magnesium aluminate spinel or spinel with TiO2 on the performance of magnesia material respectively.The results indicate that after adding 15% magnesium aluminate spinel or spinel with TiO2 in magnesia material,the sintering character and penetration resistance of samples improved,but the bend strength and corrosion resistance of samples decreased.At the same time,the magnesia material adding spinel with TiO2 has better performance than the magnesia material adding magnesium aluminate spinel.
