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.

Alkali oxide-tantalum, niobium and antimony oxide ionic conductors [PDF]

The phase equilibrium relations of four systems were investigated in detail. These consisted of sodium and potassium antimonates with antimony oxide and tantalum and niobium oxide with rubidium oxide as far as the ratio 4Rb2O:llB2O5 (B=Nb, Ta).

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.

Spray drying granulation of potassium sodium niobate (KNN) for binder jetting: Feedstock preparation and influence on sintered material properties

Open Ceramics
Binder jetting of potassium sodium niobate (K0.5Na0.5NbO3) offers potential for generating shape-dependent responses with high industrial output. However, the printing stage relies heavily on the properties of the dry feedstock, making its performance ...
