High-aluminum egg-shell reinforced celadon and preparation method thereof

The invention discloses a high-aluminum egg-shell reinforced celadon and a preparation method thereof. The high-aluminum egg-shell reinforced celadon is prepared from a high-aluminum egg-shell reinforced celadon blank and high-aluminum egg-shell reinforced celadon green glaze. The high-aluminum egg-shell reinforced celadon blank is prepared from high-aluminum egg-shell reinforced celadon slurry. The high-aluminum egg-shell reinforced celadon slurry comprises, by weight, 25-35% of Baoxi porcelain clay, 13-23% of Zhuxiang porcelain clay, 25-35% of Yuandi porcelain clay, 20-35% of alpha-Al2O3 micro-powder, 2-4% of zirconia micro-powder and 0.5-2% of PVA. The celadon green glaze comprises, by weight, 30-45% of Huangshixuan glaze clay, 20-30% of Xiyuan glaze clay, 15-25% of limestone, 4-8% of quartz and 10-20% of potassium feldspar. Through use of a proper amount of alpha-Al2O3 micro-powder and zirconia micro-powder as toughening materials in blank materials and use of PVA as a plastic adjusting agent, blank stren
