In-situ silicon carbide whisker reinforced lightweight alumina clinker and preparation method thereof
The invention relates to an in-situ silicon carbide whisker reinforced lightweight alumina clinker and a preparation method thereof. According to the technical scheme, the preparation method comprisesthe following steps of by taking 80-92wt% of alumina raw material micro powder, 5-11wt% of carbon black and 3-9wt% of silicon dioxide micro powder as raw materials, firstly, mixing the carbon black and the silicon dioxide micro powder in a planetary ball mill to obtain a mixture, adding the alumina raw material micro powder into the mixture, uniformly mixing in a planetary ball mill, and carryingout mechanical pressing under the condition of 100-200 MPa to obtain a green body, and finally, drying the green body for 12-36 hours under the condition of 110-200 DEG C, and preserving heat for 3-8hours under the condition of carbon burying at 1550-1750 DEG C to obtain the in-situ silicon carbide whisker reinforced lightweight alumina clinker. The prepared in-situ silicon carbide whisker reinforced lightweight alumina clinker has the characteristics of small pore diameter, high strength, good thermal shock resistance and strong slag resistance.
本发明涉及一种原位碳化硅晶须强化轻量矾土熟料及其制备方法。其技术方案是：以80～92wt％的矾土生料微粉、5～11wt％的炭黑和3～9wt％的二氧化硅微粉为原料，先将所述炭黑和所述二氧化硅微粉在行星球磨机中混合，得到混合料；再将所述矾土生料微粉加入到所述混合料中，在行星球磨机中混合均匀，然后在100～200MPa条件下机压成型，得到生坯；最后将所述生坯在110～200℃条件下干燥12～36小时，在1550～1750℃埋碳条件下保温3～8小时，即得原位碳化硅晶须强化轻量矾土熟料。本发明制备的原位碳化硅晶须强化轻量矾土熟料具有孔径小、强度高、抗热震性能好和抗熔渣能力强的特点。
