What are ultra-high temperature materials Ultra-high-temperature materials refer to the most heat-resistant high-grade materials that can be used as usual under severe environments such as stress and oxidation, and at an ultra-high temperature of about 2000°C. Research and application of ultra-high temperature materials 1. Refractory metal Refractory metals (W, Mo, Ta, Nb, Zr, etc.) […]
Whether you are looking to purchase a crucible for your laboratory, research, or educational institution, you’ll find that there are several options to choose from. Some of these options include boron nitride, alumina, and zirconia. alumina crucible Compared to Alumina, zirconia crucibles are better in three aspects: high melting point, excellent chemical inertness, and good […]

Refractory ceramics are a material used in a variety of industrial applications at high temperatures. They provide strength, protection from corrosion, and thermal insulation. In fact, refractories are essential for manufacturing everything from hospital beds to ambulances. Not only do these materials provide strength and resistance to heat and chemicals, but they also contribute to […]
Pyrolytic Boron Nitride, abbreviated as Pyrolytic BN or PBN, also known as Chemical vapour-deposited Boron Nitride, Chemical Vapour-deposition of Boron Nitride or CVD-BN, etc. As the name suggests, this is a kind of boron nitride prepared by high temperature pyrolysis reaction by chemical vapor deposition method. Pyrolytic Boron Nitride (PBN) material has high purity, chemical […]

The atomization method is a powder preparation method in which a fast-moving fluid (atomization medium) impacts or otherwise breaks the metal or alloy liquid into fine droplets, and then condenses into a solid powder. The atomized powder particles not only have the same uniform chemical composition as the established molten alloy, but also due to […]
The alloying principle of molybdenum is similar to that of tungsten. All the strengthening methods used to improve the heat resistance of tungsten are basically applicable to molybdenum. There are mainly the following types: solid solution strengthening, precipitation strengthening, dispersion strengthening and composite strengthening. Solution strengthening Solid solution strengthening includes the addition of trace elements […]
