Chromium Titanium Aluminum Carbide MAX Phase Powder

Chromium Titanium Aluminium Carbide MAX Phase Powder (Cr-Ti-Al-C) MAX phase powder is a sophisticated material belonging to the MAX phase family, known for combining metallic and ceramic properties. The general formula for MAX phases is Mn_nnAXn−1_{n-1}n−1, where M represents early transition metals (chromium and titanium in this case), A is an A-group element (aluminium), and X is carbon..

Properties and Characteristics

Thermal Stability: Cr-Ti-Al-C MAX phase powders are highly stable at elevated temperatures, maintaining their structural integrity under thermal stress.

Mechanical Strength: These materials exhibit a high degree of mechanical strength and hardness, characteristic of ceramics, while also offering some degree of plasticity and damage tolerance similar to metals.

Oxidation Resistance: The presence of aluminium contributes significantly to the oxidation resistance of Cr-Ti-Al-C Chromium Titanium Aluminium Carbide MAX Phase Powder making them suitable for applications in oxidative and high-temperature environments.

Electrical Conductivity: Unlike many ceramics, Cr-Ti-Al-C MAX phases have good electrical conductivity, allowing for their use in electrical and electronic applications.

Ductility: The material displays good ductility, especially at high temperatures, enabling it to undergo plastic deformation without breaking, a rare trait in ceramics.

Corrosion Resistance: The combination of chromium, titanium, and aluminium contributes to the excellent corrosion resistance of these Chromium Titanium Aluminium Carbide MAX Phase Powder, protecting them from chemical attack in harsh environments.

Synthesis and Processing

Raw Material Selection: High-purity chromium, titanium, aluminium, and carbon sources are chosen to ensure the desired stoichiometry and purity.

Mixing and Milling: The raw materials are mixed in precise stoichiometric ratios and subjected to ball milling to achieve a homogeneous mixture and refine the particle size.

High-Temperature Sintering: The blended powder is sintered at high temperatures (typically above 1200°C) in an inert or reducing atmosphere. This step allows for the formation of the Chromium Titanium Aluminium Carbide MAX Phase Powder structure.

Applications

Aerospace: Due to their high thermal stability, mechanical strength, and oxidation resistance, Cr-Ti-Al-C MAX phase powders are used in aerospace components, such as turbine blades and heat shields.

Electronics: The electrical conductivity and thermal management properties make these materials suitable for electronic components, including conductive coatings and heat sinks.

Energy Sector: These Chromium Titanium Aluminium Carbide MAX Phase Powder are explored for applications in nuclear reactors and other energy systems due to their ability to withstand high temperatures and radiation.
