The invention discloses a preparation method for a ceramic plunger and relates to a preparation method for a high-aluminium ceramic plunger pump. The invention is characterized in that: bauxite clinker, Alpha-Al2O3, barium carbonate, quartz, chromium oxide, cooked talc and Lushan clay materials are employed as raw material, grinded, then added with small amount of Arabic gum water solution and water evenly mixed; the next steps are casting, embryonic plant drying and calcinating. By adopting industrial bauxite clinker as raw material to make a high-aluminium ceramic plunger pump, the inventionhas low cost, and by adopting casting, expensive cost for mechanical equipment is saved, thus reducing production cost; in addition, the high-aluminium ceramic plunger pump produced by the method haslong service life and is easy to be popularized in the industrial field.
