Overview of Niobium Boride NbB2 Powder
The chemical formula of niobium boride is NbB2 and the molecular weight is 114.528. It is a gray-black powder, niobium boride (NbB2) has the characteristics of high melting point, high hardness, good electrical and thermal conductivity, corrosion resistance to molten metal, superconductivity, etc., and can be used to produce ultra-high temperature structural materials And superconducting materials have important applications in extreme environments such as ultra-high temperature and metal smelting. Niobium diboride (NbB2) is a highly covalent refractory ceramic material with a hexagonal crystal structure.
Preparation of Niobium Boride NbB2 Powder
1. Raw material preparation
The first step: uniformly mix niobium pentoxide powder with a particle size of 0.1 μm, 3 μm boron carbide powder and 3 μm B2O3 powder at a ratio of 70:14:3 to obtain raw material powder 1.
The second step: the above-mentioned raw material powder 1 and phenolic resin are mixed uniformly in a mixer at a weight ratio of 5:0.5, cured at a temperature of 80°C, and then crushed in a powder mill to obtain an average particle size of 10μm raw material powder 2.
The third step: the above-mentioned raw material powder 2 and phenolic resin are mixed uniformly in a mixer at a weight ratio of 5:1, cured at a temperature of 50°C, and then pulverized in a powder mill to obtain an average particle size of 20μm raw material powder 3.
The fourth step: the above-mentioned raw material powder 3 and phenolic resin are mixed uniformly in a mixer at a weight ratio of 5:2, cured at a temperature of 40°C, and then pulverized in a powder mill to obtain an average particle size of 50μm raw material powder 4.
2. Synthesis of niobium boride powder
The raw material powder 4 was compacted under a pressure of 0.5Mpa, and then fired in an argon atmosphere at a temperature of 1350°C for 6 hours to obtain a niobium boride block.
3. Decarbonization treatment
The niobium boride block is kept in an oxidizing atmosphere at a temperature of 350° C. for 12 hours to decarburize, and then pulverized to obtain a niobium boride powder after cooling.
