Synthesis and characterizations of lead free KNNT & Ni doped KNNT ceramics [PDF]

, 2012
In order to replace the lead based ceramics with the same properties of piezoelectricity and other electrical properties, lead free ceramics like KNNT perovskites were developed.. The samples with KNNT and Ni-doped KNNT ceramics were prepared.

Highly transparent lead-free piezoelectric haptic device

Communications Materials
Acoustic haptic technology adds touch sensations to human-machine interfaces by integrating piezoelectric actuators onto touchscreens. Traditional piezoelectric haptic technologies use opaque lead-containing ceramics that are both toxic and visible.

Hydrothermal synthesis of KNbO_3 and NaNbO_3 powders [PDF]

, 2003
Orthorhombic KNbO_3 and NaNbO_3 powders were hydrothermally synthesized in KOH and NaOH solutions (6.7–15 M) at 150 and 200 °C. An intermediate hexaniobate species formed first before eventually converting to the perovskite phase.
