Silicon Nitride in Energy Applications

Many new technologies for energy production and storage require new materials that can withstand high temperatures and corrosive environments. Ceramics are key materials for many different products used for energy conversion, storage, transfer, and distribution. Because ceramics—especially silicon nitride—have superior strength, wear, temperature and corrosion resistance, and insulating, conducting, or superconducting characteristics, they are extremely suitable for energy applications1.

Corrosion and Temperature Resistant

In energy conversion, ceramics are found in solar cells and solar collectors that transform solar energy to electricity. In fuel cells and batteries that change chemical to electrical energy, ceramics can withstand the corrosive nature and high temperatures required to operate2. In thermoelectric generators that convert heat to power and in gas turbines that produce mechanical energy from chemical energy, the strength and toughness that ceramics provide allow these systems to operate at peak efficiency.

Silicon nitride is an ideal material for these applications due to its excellent thermal shock resistance, strength, toughness, and chemical inertness.
