What is tantalum carbide used for?
What is tantalum carbide used for?
Tantalum carbide is widely used as sintering additive in ultra-high-temperature ceramics (UHTCs) or as a ceramic reinforcement in high-entropy alloys (HEAs) due to its excellent physical properties in melting point, hardness, elastic modulus, thermal conductivity, thermal shock resistance, and chemical stability, which …
How strong is tantalum carbide?
By testing Vickers hardness, fracture toughness, and relative density of a series of samples, it can be confirmed that the TaC possesses the best mechanical properties under 5.5 GPa and 1300 °C. The relative density, fracture toughness, and Vickers hardness of TaC are 97.7%, 7.4 MPa m1/2 and 21.0 GPa, respectively.
How hard is tantalum carbide?
Tantalum carbide (TaC) nanoparticles exhibit hardness which is greater than that of diamond. These particles are produced by the process of sintering. Another distinction associated with tantalum carbide is that it is a stoichiometric binary compound having the highest melting and boiling points.

Is tantalum heavier than tungsten?
tungsten, the biggest difference comes down to hardness. Tungsten has that natural gunmetal color, but it is not as heavy or scratch-resistant as tantalum; whereas tantalum is shatter-resistant, standing up to whatever you put it up against, tungsten is shatterproof.
What is the melting point of tantalum carbide?
7,016°F (3,880°C)Tantalum carbide / Melting point
How much does hafnium carbide cost?
Ta4HfC5 was manufactured by Goodfellow company as a 45 µm powder at a price of $9,540/kg (99.0% purity).
Can tantalum break?
Few metals are as durable as tantalum. Tantalum is highly resistant to scratching and breakage, making it perfect for people with active lifestyles and busy hands.
Is tantalum better than titanium?
The primary difference between titanium and tantalum comes down to weight and scratch-resistance. Titanium is much lighter than tantalum, and some men might prefer having a heavy ring they can feel on their fingers. On the other hand—well, not really—tantalum is not as scratch-resistant as titanium.
How much does tantalum carbide and hafnium carbide cost?
How strong is Tantalum hafnium carbide?
Tantalum hafnium carbide has high resistance to oxidation, has a high intensity, the degree of hardness is very high, its thermal conductivity based on the individual conductivities of its components, being that of tantalum 57 W/m-K, that of hafnium 23 W/m-K, and that of carbon 129 W/K-m, is very good.
Is tantalum stronger than steel?
Tantalum: “Ta” is stronger and heavier than most other metals used in wedding bands. Tantalum wedding bands are both rare and highly corrosion resistant. Stainless Steel: “SS” is a great choice for a wedding band. Its very durable, tarnish and corrosion resistant, hypo allergenic.
