Preparation of Niobium Boride Powder
1. Raw material preparation
Step 1: Set the granularity to 0.1 μ M niobium pentoxide powder, 3 μ M Boron carbide powder and 3 μ The raw material powder 1 was obtained by uniformly mixing the mB2O3 powder in the ratio of 70 ∶ 14 ∶ 3.
Step 2: Mix the above raw material powder 1 and phenolic resin in a mixing mill with a weight ratio of 5:0.5, cure them at 80 ℃, and then crush them in a pulverizer to make an average particle size of 10 μ M raw powder 2.
Step 3: Mix the above raw material powder 2 and phenolic resin at a weight ratio of 5:1 in a blender, cure them at 50 ℃, and then crush them in a pulverizer to make an average particle size of 20 μ M Raw powder 3.
Step 4: Mix the above raw material powder 3 and phenolic resin at a weight ratio of 5 ∶ 2 in a blender, cure them at 40 ℃, and then crush them in a pulverizer to make an average particle size of 50 μ M Raw powder 4.
2. Synthesis of Niobium Boride Powder
The above raw material powder 4 is pressed into blocks under the pressure of 0.5Mpa, and then fired in argon atmosphere at 1350 ℃ for 6h to obtain niobium boride blocks.
The application of niobium boride NbB2 powder
NbB2 is an ultra-high temperature ceramic (UHTC) with a melting point of 3050°C. Its relatively low density (approximately 6.97 g/cm3) and good high-temperature strength make it a candidate for high-temperature aerospace applications (such as hypersonic flight) or rocket propulsion systems. Ceramic has high thermal conductivity and electrical conductivity (resistivity of 25.7ΩYbcm, Cte of 7.7 Yb10 -6°C-1), and has the same.
Titanium diboride, zirconium diboride, ha diboride and tantalum diboride with the same structure of NboB2 have the same performance. The parts are usually hot pressed or spark plasma sintered (applying mechanical pressure to the heated powder), and then processed into shapes. The covalent nature of NbB2 and the presence of surface oxides hinder the sintering of NbB2, which then makes the particles coarser and then densify during the sintering process. By using sintering additives such as boron carbide and carbon, NbB2 can be sintered without pressure. These sintering additives react with surface oxides to increase the sintering force, but the mechanical properties of NbB2 decrease compared with hot press sintering.
