Formula for reducing ceramic sintering temperature
The invention discloses a formula for reducing a ceramic sintering temperature. The formula comprises the following components in parts by weight: 100 parts of aluminum oxide, 12-15 parts of a sintering aid, 7-9 parts of nano titanium dioxide and 1-1.4 parts of lithium oxide, wherein the sintering aid comprises the following components in percentage by mass: 11.5%-11.8% of magnesium oxide, 8.2%-9.3% of calcium oxide, 0.1%-0.2% of nickel oxide, 12.5%-23.2% of yttrium oxide, 0.4%-0.7% of barium carbonate, 0.3%-0.5% of barium oxide, 0.3%-0.5% of copper oxide and the balance of calcined kaolin. The selected sintering aid can form a multi-element low-temperature eutectic oxide in the sintering process, and is matched with the nano titanium dioxide, so that the sintering temperature of the ceramic is effectively reduced, the energy consumption is reduced, and the mechanical property of the ceramic is ensured.
本发明公开了一种降低陶瓷烧结温度的配方，按重量份数包括：氧化铝100份，烧结助剂12‑15份，纳米二氧化钛7‑9份，氧化锂1‑1.4份；其中，烧结助剂按质量百分数包括：氧化镁11.5％‑11.8％、氧化钙8.2％‑9.3％、氧化镍0.1％‑0.2％、氧化钇12.5％‑23.2％、碳酸钡0.4％‑0.7％、氧化钡0.3％‑0.5％、氧化铜0.3％‑0.5％、余量为煅烧高岭土。本发明选择的烧结助剂可以在烧结过程中形成多元低温共熔氧化物，配合纳米二氧化钛，不仅有效降低了陶瓷的烧结温度，减少了能耗，还保证了陶瓷的机械性能。
