Potassium niobate (KNbO3) is a perovskite ferroelectric crystal. It has nonlinear optical coefficient properties, making it common in the manufacture of lasers.

Chemical formula:KNbO3

Molar mass:180.003 g·mol−1

Appearance:White rhombohedral crystals

Density:4.640 g/cm3

Melting point:≈ 1100 °C


Potassium niobate has been found useful in many different areas of materials science research, including properties of lasers, quantum teleportation, and it has been used to study the optical properties of particulate composite materials.

In addition to research in electronic memory storage, potassium niobate is used in resonant doubling, a technique developed at the IBM Almaden Research Center. This technique allows small infrared lasers to convert output into blue light, a critical technology for the production of blue lasers and technology dependent upon them.
