Breaking the 500°C Limit! SICCAS Publishes in Top Journal Featuring MatMeas/Partulab High-Temperature Testing Systems

Recently, the prestigious Journal of the American Ceramic Society (JACerS) published a groundbreaking research paper from the team led by Prof. Zhiyong Zhou at the Shanghai Institute of Ceramics, Chinese Academy of Sciences (SICCAS).

The research team successfully developed a novel Cr2O3-doped NBT-based (Na0.5Bi4.5Ti4O15) high-temperature piezoelectric ceramic (CNBT-Cr20). In cutting-edge fields such as aerospace and automotive electronics, sensors are often required to operate flawlessly in extreme thermal cycling environments exceeding 500°C, placing immense demands on core piezoelectric materials. This newly engineered material not only achieves an impressive Curie temperature (Tc) of 655°C and a nearly doubled piezoelectric coefficient (d33 of 29 pC/N), but also maintains an exceptional DC resistivity of over 10⁶ Ω·cm at a blistering 500°C, showing immense potential for industrial applications.

🔬 The Ultimate "Touchstone" for Extreme Environment Data: MatMeas (Partulab) Testing Systems

Capturing the subtle changes in dielectric constant, dielectric loss, and resistivity under such extreme ultra-high temperatures pushes the anti-interference capabilities and temperature-control precision of testing equipment to their absolute limits. In this heavyweight research, the core high-temperature electrical characterization data was reliably secured and validated by MatMeas (Partulab) testing equipment:

1. DMS-1000 Impedance Material Analyzer

To verify the material's Curie temperature (Tc) and dielectric stability, the researchers utilized the DMS-1000 to precisely measure the dielectric constant and loss versus temperature. With its highly stable wide-temperature heating zone and high-precision shielding design, the DMS-1000 helped the researchers perfectly capture the sharp dielectric peaks around 655°C and accurately confirmed the material's excellent low dielectric loss characteristics after doping.

Data acquired via Partulab (MatMeas) DMS-1000 system. In the extreme temperature region exceeding 500°C, the dielectric curves remain smooth and precise.

2. HRMS-900 Conductivity Measurement Device

When exploring the internal defect concentration and the complex transition of conduction mechanisms (from hole conduction to ionic conduction) at elevated temperatures, the team relied on the HRMS-900 system. This device accurately tracked the DC resistivity and activation energy (Ea) of the samples at extreme temperatures up to 500°C and beyond. The precise data successfully proved that the novel ceramic maintains extremely low leakage currents at ultra-high temperatures, providing robust data support for its practical applications.

📈 More Scientific Research Data & Characterization

To obtain comprehensive and reliable piezoelectric and electrical responses, the research team conducted multi-dimensional characterizations using the MatMeas systems. These high-precision curves systematically reveal the deep modulation effects of Cr2O3 doping on internal structural defects and electrical conduction mechanisms of the novel high-temperature piezoelectric ceramics:

Top-Tier Research Requires Top-Tier Infrastructure

As the saying goes, "Good tools are prerequisite to the successful execution of a job." The continuous breakthroughs published in international top-tier journals by leading research institutions like SICCAS serve as the strongest testament to the irreplaceable reliability and high precision of MatMeas (Partulab) systems in the field of "Extreme Environment Electrical Characterization."

Whether it is the DMS-1000 series covering room temperature up to 1000°C, or the DMS-2000 system designed for cryogenic vacuum environments, MatMeas is dedicated to providing global material scientists with world-class, ultra-precise electrical testing infrastructure.
