High-thermal-conductivity transparent ceramic and preparation method thereof
The invention relates to the field of ceramic production, and provides a high-thermal-conductivity transparent ceramic and a preparation method thereof. The problem that a ceramic plate is relativelyweak in thermal conductivity is solved. The preparation method comprises the following steps: S10, taking, by mass, 7-10 parts of sodium sand, 5-8 parts of potassium feldspar, 40-60 parts of aluminumoxide powder, 1-3 parts of high-potassium sand, 1-3 parts of potassium-sodium feldspar, 0.5-2 parts of barium carbonate, 10-12 parts of cordierite and 1-3 parts of calcium phosphate; S20, mixing the sodium sand, potassium feldspar, aluminum oxide powder, high-potassium sand, potassium-sodium feldspar, barium carbonate, calcium phosphate and cordierite, carrying out wet ball milling to prepare slurry, drying and smashing the slurry to obtain a base material, mixing alumina microspheres, 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 in a kiln at the temperature of 1600-1700 DEG C to obtain the high-thermal-conductivity transparent ceramic. The light transmittance of the ceramic is improved, and meanwhile, the thickness and the heat conduction capability of the ceramic are improved.
