The AZT and AZTn samples (samples “1”) were sintered in air at 1650 °C with a holding time of 2 h. In order to determine suitable thermal conditions for the formation of aluminum titanate (samples “2”), the green bodies prepared from the Al2O3/TiO2 powder mixture were heat-treated in air at two different temperatures (1500 °C and 1650 °C) and holding times (2 h and 4 h). The crystalline phase content in the heat-treated samples was analyzed by X-ray diffraction. Based on the results, which will be presented in the “Results and Discussion” section, 1650 °C and 4 h holding time were chosen for the synthesis of Al2TiO5. The same temperature and holding time were used for sintering the spinel samples containing pre-synthesized Al2TiO5 and the pure spinel samples (samples “3”). For investigating their resistance to thermal shock, the sintered AZT, AZTn, and spinel samples were heated for 15 min at 950 °C, 1150 °C, or 1200 °C and then quenched by plunging in water which had a temperature of 25 °C. The mechanical strength of as-sintered samples and of samples after one and after five quenching cycles were measured by three-point bending tests (testing instrument TIRAtest 2420, Germany). |

AZT和AZTn樣品(樣品“1”) 的燒結(jié)是在空氣中1650°C和保持時間2小時。 為了確定形成鈦酸鋁(樣本“2”) 合適的熱條件，從氧化鋁/二氧化鈦粉末混合物制備生坯(未燒試樣)，在空氣中以兩種不同溫度(1500°C和1650°C)熱處理且保持時間(2 h和4 h)。熱處理樣品的結(jié)晶相含量由X射線衍射分析(確定)�；谶@些結(jié)果，它將在“結(jié)果與討論”部分呈現(xiàn)，1650°C和4h保持時間被選擇做Al2TiO5的合成。 同樣的溫度和保持時間被用于燒結(jié)含預(yù)合成Al2TiO5的尖晶石樣品和純尖晶石樣品(樣品“3”)。 為研究他們的抗熱沖擊，燒結(jié)的AZT，AZTn和尖晶石樣品在950°C、1150°C和1200°C加熱15分鐘，然后浸入25°C水中淬火。該燒結(jié)樣品和1和5淬火周期后樣品的機械強度，由三點彎曲試驗(測試儀器TIRAtest 2420，德國) 測量。 |
