Siliceous domestic ceramic with high light transmittance and high whiteness and preparation method thereof

The invention belongs to the technical field of domestic ceramics, and particularly discloses a high-transmittance and high-whiteness siliceous domestic ceramic and a preparation method thereof. The siliceous domestic ceramic comprises a green body layer and a cover glaze layer, wherein the green body layer comprises the following components in parts by weight: 20-22 parts of aluminum washing mud; 5-10 parts of silica fume; 10 to 15 parts of diatomite; 24 to 26 parts of siliceous frit; 12 to 15 parts of aluminous potassium feldspar; 5 to 10 parts of transparent sillimanite; 7 to 9 parts of bentonite; and 2-4 parts of calcium phosphate. According to the invention, the silica fume, the siliceous frit and the diatomite are used as main silicon sources to prepare the high-siliceous domestic ceramic; aluminum potassium feldspar, aluminum washing mud and transparent sillimanite are added for introducing an aluminum source and a low-temperature flux, a certain amount of calcium phosphate is added, and all the raw ma
