The invention discloses a high alumina full ceramic ball arch, comprising following raw materials: calcined alumina, active alumina, feldspar powder, Qingyuan petuntse, Fujian petuntse, Zuoyun soil and Handan soil. The preparation method of the high alumina full ceramic ball arch comprising the following steps: firstly, adding the calcined alumina, the active alumina, the feldspar powder, the Qingyuan petuntse, the Fujian petuntse, the Zuoyun soil and the Handan soil into a globe mill in a certain proportion and evenly mixing the mixture; secondly, mixing and ball milling the mixture with dolomite; thirdly, milling with proper amount of water to form sizing agent; and finally staling, extracting, molding, drying and firing the sizing agent to obtain the high alumina full ceramic ball arch.The high alumina full ceramic ball arch greatly improves the intensity of the ball arch, can lighten the weight of the ball arch, reduces the depth of small brick body, increases the superficial areaof holes in the ball arc,
