Zirconium nitride (ZrN) is an insoluble compound, insoluble in water, only slightly soluble in inorganic acids, has good physical and chemical stability, high hardness, high melting point, high temperature resistance, corrosion resistance, w

Zirconium nitride compounds have various crystal structures depending on the composition. For example, in the Zr-N alloy system, the alloy compounds found are ZrN, O-ZrN and C-ZrN.

Cobalt boride is an inorganic compound with the general formula CoxBy. There are two main types of cobalt boride CoB and Co2B. Cobalt boride is a compound with excellent oxidation resistance and can be used for high corrosion resistance and

Hafnium, chemical symbol Hf, atomic number 72, melting point 2233℃, is a high melting point rare metal. Metal hafnium forms a layer of oxide film in the air, with strong corrosion resistance and stable chemical properties. Metal hafnium p

Zirconium carbide (ZrC) is one of the important high-temperature structure materials with various physical-chemical properties, such as high melting point (3 550℃), high hardness (25 GPa),high corrosion and wear resistance, and high elect

Due to their excellent properties such as high melting point, high electrical conductivity, high oxidation resistance and good chemical stability, transition metal diboride (ZrB2, HfB2) based ceramics have good potential for various aviation

Important properties of powders can be grouped into four categories: (1) physical properties, (2) chemical composition, (3) phase composition, and (4) surface properties.

LaB6 powder (lanthanum boride) was originally mainly used in military industry, aviation, aerospace and some high-tech fields. With the maturity of manufacturing technology, the reduction of production cost and the wider range of applicatio
