Global Hydrogen Mass Flow Meter Market Growth 2025-2031

The global KNN-based Piezoelectric Ceramics market size is predicted to grow from US$ 14.9 million in 2025 to US$ 37.6 million in 2031; it is expected to grow at a CAGR of 16.7% from 2025 to 2031.

The impact of the latest U.S. tariff measures and the corresponding policy responses from countries worldwide on market competitiveness, regional economic performance, and supply chain configurations will be comprehensively evaluated in this report.

Potassium sodium niobate (KNN) is a perovskite-structured material with the chemical formula (K,Na)NbO3. KNN is a lead-free ferroelectric material with excellent piezoelectric properties, used in sensors, actuators, and energy harvesting devices. It is a promising alternative to lead-based piezo ceramics in the field of electromechanical conversion.

Key Market Trends:

High-performance Material Optimization: Ongoing research focuses on improving piezoelectric coefficients and thermal stability through doping strategies (e.g., Li, Sb) and advanced sintering techniques like two-step sintering (TSS), which reduces alkali metal volatility and enhances densification.

Policy-Driven Market Growth: Stricter environmental regulations (e.g., EU RoHS, China's "Dual Carbon" policy) mandate lead-free alternatives, accelerating KNN adoption in consumer electronics and industrial sectors.

Key Market Drivers:

Driver 1: Regulations are in place to restrict the use of lead in commercial products and these are expected to become even stricter in the future. For example, the draft revision of the EU RoHS Directive has clearly tightened the lead content limit of piezoelectric materials from the current 0.1% to 0.05%. The search for lead-free alternatives to Pb(Zr, Ti)O3 (PZT) piezoelectric ceramics has become a major topic in functional materials research due to legislation in many countries that restricts the use of lead alloys and compounds in commercial products.

Driver 2: At present, the development of lead-free piezoelectric ceramics is that a variety of materials coexist, and different lead-free materials have their own characteristics. However, KNN is the material closest to PZT and is very likely to replace the currently widely used PZT ceramics.

Key Market Restraints:

Technical Performance Gaps: KNN ceramics still lag behind lead-based materials (e.g., PZT) in piezoelectric coefficients, temperature stability, and mechanical durability, limiting applications requiring high precision or extreme environments.
