Tantalum hafnium carbide is a refractory chemical compound with a general formula Ta x Hf y C x+y, which can be considered as a solid solution of tantalum carbide and hafnium carbide. It was originally thought to have the highest melting of any known substance but new research has proven that hafnium carbonitride has a higher melting point.
Hafnium carbide (Hf C) is a chemical compound of hafnium and carbon.Previously the material was estimated to have a melting point of about 3,900 °C. [2] More recent tests have been able to conclusively prove that the substance has an even higher melting point of 3,958 °C exceeding those of tantalum carbide and tantalum hafnium carbide which were both previously estimated to be higher.

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 makes it a desirable ...

The mixed carbide tantalum hafnium carbide (Ta 4 HfC 5) possesses the highest melting point of any currently known compound, 4,263 K (3,990 °C; 7,214 °F). [21] Recent supercomputer simulations suggest a hafnium alloy with a melting point of 4,400 K. [22] Hafnium forms both a hafnium(III) and a hafnium(IV) nitride.
Hafnium carbide is the most refractory binary compound known, with a melting point of 3890 °C. [8] [9] The ternary compound tantalum hafnium carbide has one of the highest melting points of all known compounds (4215 °C). [10] [11] Molybdenum disilicide has a high melting point of 2030 °C and is often used as a heating element.
Seed oils — plant-based cooking oils often used in processed, packaged foods — have been linked to an increased risk of colon cancer, according to a new study published in the medical journal Gut.
It’s important to store and use cooking oil properly, says Czerwony. Choose oil in dark, opaque bottles which protect it from light. Store oil in a dark, cool place to avoid oxidation or ...
