What is Hafnium Disilicide Powder?
Hafnium silicide is a transition metal silicide, a refractory intermetallic compound.
The main features of Hafnium Disilicide Powder
Hafnium silicide HfSi2 powder (CAS 12401-56-8) has high melting point, high corrosion resistance, high oxidation resistance, good electrical conductivity, high temperature ductility, a binary alloy systemthe intermediate phase, dual characteristics of metals and ceramics.
The applications of Hafnium Disilicide Powder
1. Prepare an organic electroluminescence device. It includes an anode, a light-emitting layer, a cathode, and a packaging cover stacked in sequence. The packaging cover encapsulates the light-emitting layer and the cathode on the anode. The packaging cover includes a silicon carbonitride layer and a barrier layer formed on the surface of the silicon carbonitride layer The material of the barrier layer includes silicide and metal oxide, the silicide is selected from at least one of chromium silicide, tantalum disilicide, hafnium silicide, titanium disilicide, molybdenum disilicide and tungsten disilicide, the The metal oxide is selected from at least one of magnesium oxide, aluminum oxide, titanium oxide, zirconium oxide, hafnium oxide, and tantalum pentoxide. The above-mentioned organic electroluminescent device has a long life. The invention also provides a method for preparing the organic electroluminescent device.
2. Preparation of a silicon-germanium alloy-based thermoelectric element. The silicon-germanium alloy-based thermoelectric element is composed of an electrode layer, a silicon-germanium alloy-based thermoelectric layer, and a barrier layer between the electrode layer and the silicon-germanium alloy-based thermoelectric layer, and the barrier layer is a mixture of silicide and silicon nitride, The silicide is at least one of molybdenum silicide, tungsten silicide, cobalt silicide, nickel silicide, niobium silicide, zirconium silicide, tantalum silicide, and hafnium silicide. The provided silicon-germanium alloy-based thermoelectric element has a good combination of interfaces, no cracks and obvious diffusion phenomena at the interface, low contact resistance, good thermal contact state, and can withstand long-term high-temperature accelerated tests. In addition, the provided preparation method has the characteristics of simple process, high reliability, low cost, no need for special equipment, and suitable for large-scale production.
3. Prepare a high temperature and oxidation resistant metal ceramic composite coating. The composite film is characterized in that the coating is composed of refractory metal, refractory carbide and intermetallic compound, and the thickness of the coating is 10 μm-50 μm. The refractory metal is one or more of molybdenum, tantalum, zirconium and hafnium; the composition of the refractory carbide is silicon carbide, and one or more of tantalum carbide, zirconium carbide and hafnium carbide The composition of the intermetallic compound is one or more of molybdenum silicide, tantalum silicide, zirconium silicide, hafnium silicide, tantalum silicide, zirconium carbon silicide and hafnium silicide; the crystal structure of the coating is composed of non- Composition of crystalline and/or polycrystalline nanoparticles.
