The invention provides a preparation method of a low-expansion ceramic billet. The preparation method comprises the following steps: providing the following raw materials in percentage by weight: 15 to 20 percent of cordierite, 16 to 20 percent of petalite, 16 to 20 percent of talc, 4 to 7 percent of mullite and 40 to 43 percent of kaolin; carrying out wet ball grinding on the talc, the mullite, the kaolin and a solvent, thus preparing an initial billet with particle size distribution D97 being 12 to 15 micrometers; carrying out wet ball grinding on the cordierite, the petalite and the initialbillet, thus preparing the low-expansion ceramic billet with particle size distribution D97 being 60 to 80 micrometers. According to the preparation method, the use amount of the petalite is reduced,and the raw material cost is reduced; furthermore, the prepared low-expansion ceramic billet is applicable to relatively-low-cost rolling forming of equipment, but not limited to isostatic forming.
