Product Information - Mullite Rulaistar

Mullite is an alumino silicate with high refractoriness. Refractory grade calcined bauxite and kaoline are homogeneously mixed in a ratio according to the required chemical and mineralogical composition. Our standard grades have 45/47/60/70 % Al2O3. The products are calcined in modern rotary kilns, the length and calcining temperature ensure a complete mullitezation. Rulaistar Mullites have a high thermal volume stability and high thermal shock resistance. Rulaistar Mullites ar characterized by an excellent high temperature creep and corrosion resistance.
