烧结莫来石采用优质天然铝矾土为原料,经过多道精选工序和多级均化,经1750℃以上高温烧结而成。莫来石具有含量高、体积密度大,热震动稳定性好、高温蠕变值小和抗化学腐蚀性好等特点,因其良好的质量稳定性能,莫来石是生产各种定型与不定性耐火材料、高级卫生洁具坯体、坩埚、匣钵、精密铸造等产品的理想原料。
Sintered mullite using high-quality natural bauxite as raw materials, is proceeded iwth multi-channel selection process and multistage homogenization, melted and refined with more than 1750 ℃ high temperature. Mullite has the characteristics of high content, large volume density, good thermal vibration stability, low high-temperature creep value and good chemical corrosion resistance. Because of its good quality and stability performance, Mullite is the production of a variety of stereotypes and non-qualitative refractories, advanced sanitary ware billet, crucible, sager, precision casting and other products ideal raw materials.
