Concerning Tantalum Light Weight Aluminum Carbide Ta2AlC Powder:

Physical property

Hardness: tantalum aluminum carbide has a high hardness, second only to diamond and boron carbide. At room temperature, its hardness can reach 8000 ~ 9000kg/mm2, and at 250 ° C, the hardness decreases slightly but still maintains 5000 ~ 6000kg/mm2.

Melting point: The melting point of tantalum aluminum carbide is as high as 3450 ° C, much higher than most metals and alloys. This means that tantalum aluminum carbide can maintain good stability and performance. Under a high-temperature environment.

Conductivity: The conductivity of tantalum aluminum carbide is low, 10-4 ~ 10-3s/cm. Although its conductivity is not high, the stability of tantalum aluminum carbide at high temperatures still has a specific application value in electronics.

Chemical properties

Stability: tantalum aluminum carbide has good chemical stability at high temperatures and can resist the erosion of most acids and bases. In addition, it can also remain stable in high-temperature oxidation environments and is not easily oxidized.

Corrosion resistance: tantalum aluminum carbide is highly resistant to most corrosive media. At room temperature, it is not easily attacked by acids and alkalis, and its corrosion resistance is better at high temperatures.

Oxidation resistance: tantalum aluminum carbide has good oxidation resistance at high temperatures. Its surface will form a dense oxide film in the air, preventing further oxygen penetration and erosion. This allows tantalum aluminum carbide to remain stable under high-temperature oxidation conditions.

Mechanical properties

Strength: tantalum aluminum carbide has very high strength; its tensile strength can reach 1800MPa, and compressive strength can reach 3500MPa. These excellent mechanical properties make it stable when subjected to high loads and complex stress fields.

Toughness: Although tantalum aluminum carbide has a high hardness, its toughness is also relatively good. At low temperatures, its toughness can reach 15 ~ 20MPa·m1/2. At high temperatures, its toughness decreased slightly but maintained a high level.

Fatigue properties: tantalum aluminum carbide has good fatigue properties under cyclic loading conditions. The fatigue limit can reach 10^7 ~ 10^8 cycles at room temperature and high temperature. This gives it a good application prospect in the environment subjected to alternating loads.

How is Tantalum Light Weight Aluminum Carbide Ta2AlC Powder Produced?

Production principle

The tantalum aluminum carbide production principle uses the chemical reaction between aluminum, tantalum and carbon to generate Ta2AlC compounds. The reaction must be carried out at high temperatures, usually above 1000 ° C. The specific chemical reaction is 2Ta + Al + 3C → Ta2AlC.

Production steps

Preparing raw materials: Preparing raw materials for aluminum, tantalum and carbon, usually using metal powder or ceramic particles as raw materials. High-purity metal powder or specially treated alloy powder is usually used for aluminum and tantalum raw materials. For carbon raw materials, graphite or activated carbon are generally used.

Mixing: The raw materials of aluminum, tantalum and carbon are mixed according to stoichiometric ratios to produce the desired compounds in the reaction. Mechanical means such as ball milling and stirring can be used to obtain a uniform mixture.

Molding: The mixed raw materials are put into the mold, and a certain pressure is applied to make a prefabricated part with a specific shape and size. In order to obtain high-density and high-strength prefabricated parts, hot pressing, cold pressing and other forming processes can be used.

Sintering: The prefabricated parts are placed in the furnace for high-temperature sintering so that a chemical reaction occurs between the raw materials to produce Ta2AlC compounds. During the sintering process, factors such as temperature, time and atmosphere must be controlled to ensure that the chemical reaction is entirely carried out and a dense compound is obtained.

Post-treatment: Necessary post-treatment, such as cooling, grinding and polishing, is carried out on the sintered prefabricated parts to obtain the desired surface finish and dimensional accuracy.
