The invention relates to the technical field of glazes, in particular to a composite zirconium white opaque frit, a preparation method thereof, an ultra-white glaze using the composite zirconium white opaque frit and a ceramic tile. The composite zirconium white opacifying frit comprises the following raw materials in parts by weight: 25-40 parts of quartz, 5-10 parts of calcined alumina, 20-35 parts of potassium feldspar, 3-10 parts of talc, 5-10 parts of calcite, 5-10 parts of calcium phosphate, 1-5 parts of calcined shells, 7-15 parts of zirconium boride, 3-10 parts of zircon sand, 1-5 parts of kaolin and 3-10 parts of zinc oxide. By adopting the raw materials of the composite zirconium white opacifying frit, the composite zirconium white opacifying frit can have a relatively high whitening effect; meanwhile, two cooling and heat preservation procedures are adopted in the cooling and heat preservation stages, the content of SiO2, P2O5 and MgO in the chemical composition of the composite zirconium white opa
