The potassium sodium niobate (KNN) single crystal was successfully prepared by the seed-free solid-state crystal growth method, and the effect of cooling rate on the structure and electricity properties of KNN single crystal was systematically studied. The results show that optimizing the cooling rate can promote the growth of single crystals, and it is easy to grow single crystals with larger sizes; when the cooling rate is lower, the crystal surface is flatter and the quality of the crystal is higher; The effect of the crystal structure of the single crystal is small; when the temperature reduction rate is 2.0 ℃/min, the prepared potassium-sodium niobate piezoelectric single crystal exhibits excellent piezoelectric properties, and its positive piezoelectric coefficient d33 reaches 510 pC/N, the inverse piezoelectric coefficient d*33 is 1 425 pm/V, and the crystal also has a lower dielectric loss tanδ=0.02, a higher Curie temperature TC=416 ℃, and a larger remanent polarization Pr=20 μC/cm2. This shows that the potassium-sodium niobate-based single crystals grown by seed-free solid-state crystal growth method by optimizing the cooling rate is a promising piezoelectric ferroelectric single crystal material and has great potential application value.

采用无籽固相晶体生长法制备了铌酸钾钠基压电单晶,研究了晶体生长降温阶段的冷却速率对该单晶的结构和性能的影响。结果表明:通过优化降温速率有利于单晶的生长,易生长尺寸更大的单晶体;当降温速率较低时,晶体表面更平坦,晶体质量较高;在研究范围内,降温速率的改变对单晶的晶体结构的影响较小;当降温速率为2.0 ℃/min时,所制备的铌酸钾钠基压电单晶表现出优异的压电性能,其正压电系数d33达510 pC/N,逆压电系数d*33达1425 pm/V,同时晶体还具有较低的介电损耗tanδ=0.02,且Curie温度较高TC =416 ℃,和剩余极化强度Pr=20 μC/cm2。通过优化降温速率采用无籽固相法生长的铌酸钾钠基单晶是一种较有前景的压电铁电单晶材料,具有较大的潜在应用价值。

采用无籽固相晶体生长法制备了铌酸钾钠基压电单晶,研究了晶体生长降温阶段的冷却速率对该单晶的结构和性能的影响。结果表明:通过优化降温速率有利于单晶的生长,易生长尺寸更大的单晶体;当降温速率较低时,晶体表面更平坦,晶体质量较高;在研究范围内,降温速率的改变对单晶的晶体结构的影响较小;当降温速率为2.0 ℃/min时,所制备的铌酸钾钠基压电单晶表现出优异的压电性能,其正压电系数d33达510 pC/N,逆压电系数d*33达1425 pm/V,同时晶体还具有较低的介电损耗tanδ=0.02,且Curie温度较高TC =416 ℃,和剩余极化强度Pr=20 μC/cm2。通过优化降温速率采用无籽固相法生长的铌酸钾钠基单晶是一种较有前景的压电铁电单晶材料,具有较大的潜在应用价值。

The potassium sodium niobate (KNN) single crystal was successfully prepared by the seed-free solid-state crystal growth method, and the effect of cooling rate on the structure and electricity properties of KNN single crystal was systematically studied. The results show that optimizing the cooling rate can promote the growth of single crystals, and it is easy to grow single crystals with larger sizes; when the cooling rate is lower, the crystal surface is flatter and the quality of the crystal is higher; The effect of the crystal structure of the single crystal is small; when the temperature reduction rate is 2.0 ℃/min, the prepared potassium-sodium niobate piezoelectric single crystal exhibits excellent piezoelectric properties, and its positive piezoelectric coefficient d33 reaches 510 pC/N, the inverse piezoelectric coefficient d*33 is 1 425 pm/V, and the crystal also has a lower dielectric loss tanδ=0.02, a higher Curie temperature TC=416 ℃, and a larger remanent polarization Pr=20 μC/cm2. This shows that the potassium-sodium niobate-based single crystals grown by seed-free solid-state crystal growth method by optimizing the cooling rate is a promising piezoelectric ferroelectric single crystal material and has great potential application value.
