High-precision Thermal Expansion Measurement for Ceramics & Solids AZA1269
The AZA1269 High-Performance Dilatometer is an advanced thermal analysis instrument engineered for precise measurement of linear thermal expansion and contraction of solid materials at temperatures up to 1400 °C. Designed for demanding laboratory and industrial environments, the system delivers high accuracy, repeatability, and long-term thermal stability, making it ideal for material characterization, research, and quality assurance.
This instrument is widely used in ceramics, refractories, advanced composites, polymers, and sintered materials, where understanding dimensional change under heat is critical to product performance and safety.
Description
Purpose of Linear Thermal Expansion Testing
Thermal expansion analysis is essential for evaluating how materials behave when exposed to elevated temperatures. Improper expansion characteristics can lead to cracking, warping, loss of mechanical integrity, or system failure in real-world applications.
The AZA1269 enables accurate determination of:
-
Linear thermal expansion coefficient
-
Expansion and contraction behavior over temperature
-
Phase transitions and structural changes
-
Material suitability for high-temperature applications
High-Temperature Furnace System
At the core of the AZA1269 is a robust silicon carbide heating furnace (I Squared R, USA), capable of continuous operation at 1400 °C. The furnace is mounted on a guided rail movement system, allowing smooth, controlled travel for easy specimen loading and unloading while maintaining precise alignment during measurement.
