High-strength transparent ceramic and preparation method thereof
The invention relates to the field of ceramic production, and provides high-strength transparent ceramic and a preparation method thereof, which are used for solving the problem of low light transmittance of ceramic plates. The invention provides high-strength transparent ceramic. The preparation method includes steps of: S10, preparing the following raw materials comprising, by mass, 10-15 partsof sodium sand, 5-15 parts of potassium feldspar, 30-50 parts of aluminum oxide powder, 2-5 parts of high-potassium sand, 2-5 parts of potassium-sodium feldspar, 1-3 parts of barium carbonate, 1-3 parts of lithium titanate whiskers, 1-3 parts of potassium titanate whiskers, 1-4 parts of ball clay and 2-5 parts of calcium phosphate; S20, mixing sodium sand, potassium feldspar, aluminum oxide powder, high-potassium sand, potassium-sodium feldspar and the like, performing ball milling to obtain slurry, drying and crushing the slurry to obtain a base material, and mixing lithium titanate whiskers,potassium titanate whiskers and the base material, and uniformly stirring to obtain precursor powder; S30, stamping the precursor powder to form a plate blank; and S40, drying the plate blank until the water content is lower than 1%, and firing the blank in a kiln at 1600-1700 DEG C to obtain the high-strength transparent ceramic. By means of the process, the thickness, the breaking modulus and the breaking strength of the ceramic are improved.
