Application of Hafnium Silicide in Material Preparation
Hafnium silicide strength has high melting points, high corrosion resistance and high oxidation resistant, as well as good electrical characteristics.
Hafnium Silicide (transition metal silicide) is a form of refractory Intermetallic Compound. Because of its unique physical and chemical properties, it has been successfully used in complementary metal-oxide-semiconductor components, thin-film coatings, bulk structure components, electric heating Components, thermoelectric materials and photovoltaic materials. These nanomaterials possess unique electrical, optical and magnetic properties. They could also be useful in the field catalysis. The preparation of the transition metal silicides nanomaterials is not possible using traditional methods like metallurgical or physical methods. For the widespread application of transition silicide nanomaterials, it is essential to discover a method that can be controlled easily and has universal applicability.

Hafnium Silicon - Application
1. The preparation of an ablative composite coating made of silicon carbide, hafnium silicide and tantalum silicide. A new high temperature composite material called carbon fiber reinforced carbon is carbon-fiber reinforced carbon. It uses carbon fiber for reinforcement, and pyrolyticcarbon as its matrix. Its high temperature strength and anti-ablation qualities, as well as its good frictional and wear characteristics, led the United States to conduct research on carbon fiber reinforced carbon (C / C) composite materials in the 1970s. This resulted in C /C composite materials development. The thermal and structural properties of C /C composite materials are used in space shuttle nose cone caps, wing edges, gas turbine engine structural parts, as well as for other applications such as the construction of space shuttle nose cone caps or wing leading edges. Many of these parts can withstand high temperatures and oxidation.
Composites of C / C are susceptible to oxidization and should not be exposed to oxidizing conditions above 400. The preparation of antioxidation coats, which are one of the most important protective measures for C/C composite materials, is necessary. Study results have demonstrated that the additions of Zr, Hf and Ta to C / C composite materials can increase their resistance to oxidation. C /C composites' ablation resistance can be improved by adding refractory metals Zr, Hf, Ta and TiB2 to their carbon matrix. Some experiments conducted SiCHfSi2-TaSi2 antiblation coatings by embedding. To better understand the effect of Hf and T on C/C composites' ablation performance, the anti-ablation properties of this anti-ablation coat were measured with an oxyacetylene ablation apparatus.

2. Create an organic electronic luminescent device. You will need an anode with a light-emitting and cathode layers, as well as a package cover. These are ordered in a sequentially stackable fashion. The anode light emitting layer is protected by the package cover. It includes the anode's cathode and the light-emitting layer. It has an extended life span. In the invention, a process is described for making an organic electrodeluminescent device.
3. Prepare a silicon/germanium alloy-based, thermoelectric element. An electrode layer is required, along with a silicon/germanium alloy-based thermal layer. A barrier layer must be placed between the silicon/germanium layer and the silicon/germanium alloy-based temperatureelectric layer. The barrier layer contains silicide as well as silicon nitride. Silicide includes at least one silicide from each of the following: molybdenum and tungsten silicides, cobalt and nickel silicides, cobalt and nickel silicides, nickel silicides, niobium, zirconium, tantalum, hafnium, cobalt or tungsten silicides, as well as cobalt and nickel silicides. It is well-combined, there are no visible diffusion phenomena at the interface, contact resistance is low, thermal contact is good, and it can endure a long-term, high-temperature acceleration test. Additionally, this preparation has no special equipment and can be used for large-scale production.
4. A cermet composite coating that resists oxidation is possible. Refractory metals and intermetallic compound are used to make the composite film. The coating's thickness is between 10 and 50 millimeters. A refractory element is one or several of molybdenum or tantalum and zirconium. One or more hafnium, zirconium or tantalum silicides are included in the intermetallic compounds.
