Method for synthesizing cordierite refractory raw material by solid-phase reaction sintering method
The invention relates to a method for synthesizing a cordierite refractory raw material by a solid-phase reaction sintering method, which comprises the following steps: by using binding clay, talcum powder, flint clay powder and alumina which are wide in source and low in cost as raw materials, mixing, drying, grinding, forming and sintering to prepare the cordierite refractory raw material. The cordierite refractory raw material prepared through the method is low in thermal expansion coefficient, a refractory material prepared from the refractory raw material has good thermal shock resistancestability, and the comprehensive quality of the synthesized refractory material can be improved when the refractory raw material prepared through the preparation method is applied to the aspect of refractory material synthesis.
本发明涉及一种固相反应烧结法合成堇青石耐火原料的方法，以来源广泛、成本低廉的结合粘土、滑石粉、焦宝石粉、矾土为原料，经混料、干燥、研磨、成型、烧成，制备堇青石耐火原料。本发明方法制备的堇青石耐火原料热膨胀系数低，由此种耐火原料所制成的耐火材料具有较好的抗热震稳定性，通过本发明的制备方法制备的耐火原料应用在耐火材料合成方面，能够提高合成的耐火材料的综合品质。
