What material is zirconium carbide?

Zirconium carbid is an extremely hard material that has high melting points and good high-temperature resistance. You can use them to create alloy steel, and as solid fuel in rocket engines. This is also the raw material used to make zirconium metal or zirconium trioxide, as well as fine ceramic materials.

This material has a strong ZrC-C covalent bond which gives it a very high melting temperature (3530degC), high module (440 GPa), hardness (25 GPa). ZrC’s density is 6.73g/cm3 lower than that of other carbides, such as TaC (14.75 g/cm3) or WC (15.8g/cm3). ZrC may be used for supersonic or rocket/hyperjet aircrafts, which require low density and high temperatures load-bearing capacities.

Both technetium oxide (or charcoal) are the raw materials. They are combined, then heated in a hydrogen atmosphere to 2400. Mixing zirconia dioxide or carbon black is also possible. They can be molded under pressure and heated to 1800 in an Induction Heating graphite Crucible. Once the hydrogen atmosphere has passed, they are added to Iy2% carbon noir and annealed at 1600 1900 in vacuum to make zirconium carbonide. You can also mix zirconium dioxide and magnesium, then heat to 750 and pickle with hydrochloric acids to extract byproducts.

Chemical vapor deposition (CVD) is another method of manufacturing. The process involves heating the zirconium sponge, and decomposing any halide gases. The preparation of composite materials is one way to increase the resistance to oxidation. ZrC -ZrB2 is the preferred composite material. These composite materials are capable of working at temperatures above 1800 °C. This situation can be improved by using another material, like TRISO fuel particle as a barrier.

Zirconium carbonide is a cubic, shiny and gray crystalline powder. Lattice constant. 1 0. 46983nm. Melting point 3532. Boiling point 5100. Relative density 6. 73. Mohs hardness 89, microhardness 2700kg/mm. The elastic modulus of 3. 48x10sN/mm2, thermal expansion coefficient 6. The heat of formation for -196 is 73x10s N/mm2. 8kj/mol specific heat potential is 37. 8J/mol (mol-K), and resistance is 42u cm. Hydrochloric acid is insoluble. It dissolves in hydrofluoric, nitric, and hydrofluoric acids. However, it can be soluble or insoluble in hot sulfuric acid with hydrogen peroxide. The chemical reaction with chlorine can cause zirconium dioxide to be formed at higher temperatures.
