The invention discloses a formula for reducing the sintering temperature of ceramics, which comprises in parts by weight: 100 parts of alumina, 12-15 parts of sintering aids, 7-9 parts of nano-titanium dioxide, and 1-1.4 parts of lithium oxide; According to mass percentage, the ingredients include: magnesium oxide 11.5%-11.8%, calcium oxide 8.2%-9.3%, nickel oxide 0.1%-0.2%, yttrium oxide 12.5%-23.2%, barium carbonate 0.4%-0.7%, barium oxide 0.3% ‑0.5%, copper oxide 0.3%‑0.5%, and the balance is calcined kaolin. The sintering aid selected by the present invention can form multiple low-temperature eutectic oxides in the sintering process, and when combined with nano-titanium dioxide, not only effectively reduces the sintering temperature of ceramics, reduces energy consumption, but also ensures the mechanical properties of ceramics. |
