High Temperature XRD Combined with DTA/TGA/DSC Analysis

Thermal analysis and phase evolution - actionable insight for high‑temperature materials

Understanding exactly when thermal events occur and which phases form, transform, or disappear under heat is essential for engineering-dependable, high‑performance materials. Lucideon now offers a unique paired capability: High Temperature Real-Time XRD alongside Simultaneous Thermal Analysis (DTA/TGA/DSC). Together, they reveal both what happens (mass change, heat flow, reaction onset) and how the crystal structure changes at any particular temperature.

XRD

 

Overview

Our High Temperature Real‑Time XRD measures crystal structure changes in situ, while DTA/TGA/DSC pinpoints thermal events (reaction onsets, phase transitions) and mass changes (loss/gain). When run to coordinated temperature profiles, the techniques provide a synchronized view of a material’s behaviour under heat. The data generated will be hugely beneficial to material manufacturers and end users alike, whether ensuring that products are fit for purpose or investigating in cases of process failure.

What this combination reveals

  • Correlated reaction mapping: align DSC/DTA/TGA data with phase formation from XRD
  • Phase stability: determine temperature ranges where phases are stable vs. transforming
  • Crystallization & devitrification: confirm onset temperatures and quantify kinetics
  • Decomposition & volatilization: identify the mechanism and products (mass loss vs. phase formation)
  • Oxidation/reduction pathways: track mass gain/loss with evolving oxidation states and phases
  • Sintering & densification indicators: connect thermal events with peak position changes and phase evolution

Materials we test

Our combined approach suits most inorganic and hybrid materials, including:

  • Ceramics (oxide, non‑oxide), refractories, glass, and ceramic matrix composites
  • Environmental Barrier Coatings (EBCs) & Thermal Barrier Coatings (TBCs)
  • Cements, binders, bricks, & construction materials
  • Powders, granules, pellets, and coated components
  • Pharmaceutical ingredients and actives

 

 

Industries & use cases

  • Aerospace - optimize EBC/TBC systems (e.g., zirconate coatings), confirm phase stability, sintering behaviour, and thermal expansion compatibility for turbine components
  • Defense - qualify high‑temperature ceramics and refractories; assess oxidation/reduction routes under operational atmospheres
  • Pharmaceuticals - investigate active pharmaceutical ingredient (API) or excipients for thermal and phase stability; detect hydration/dehydration events and crystallinity changes
  • Construction - study cements, geopolymers, bricks, and refractory linings - binder burn‑out, carbonation, sulphate attack, and high‑temperature durability
  • Energy - optimize energy storage materials, identify oxidation/reduction and decomposition routes, investigate thermal expansion of materials

Typical questions we can answer

  • At what temperature do phase transformations start, and which phases form?
  • What is the phase stability window for my coating/system under service temperatures?
  • Does the material show undesired devitrification or residual phase formation near my operating temperature?
