Summary: In materials research, simultaneously controlling high pressure and extreme temperatures is essential for uncovering novel physical properties and synthesizing new materials.

In materials research, simultaneously controlling high pressure and extreme temperatures is essential for uncovering novel physical properties and synthesizing new materials.

Low temperature and high pressure: primarily used to study superconductivity, quantum phase transitions, and exotic electronic states.

High temperature and high pressure: can simulate planetary interior conditions and synthesize novel high-performance materials, such as ultra-hard materials and new superconductors.

Integrating a microscale thermal‑cold stage into a diamond anvil cell (DAC) or other high‑pressure apparatus enables researchers to generate precisely controlled extreme environments.

Recently, Chongguang Company successfully delivered a high-performance high-pressure heating stage to a leading university. Designed specifically for polarizing microscopes, this instrument enables experiments on acid- and alkali‑containing samples under elevated temperature and pressure conditions—ranging from ambient to 220°C and 0–1 MPa—with temperature control accuracy of ±0.05°C. It is also equipped with a pressure‑relief system to ensure experimental safety and stability.
