MULLITE 70 (M70)
Mullite 70 (M70)
Using fine quality natural bauxite as the raw material , M70 is multi-homogenized after fine selection, and is sintered at high temperature. It is characterized with high content of mullite, high bulk density, high thermal shock resistance, low creep value at high-temperature and good chemical corrosion resistance. It’s the optimal material for producing various shaped and unshaped refractories and precision casting products.
XRD analysis shows
M70 sample mainly contains mullite phase(83-88%) and a little amount of corundum (≤3%),
and traces of rutile (TiO2) and the rest is glass phase.
