What is it?

Hafnium Powder


Hafnium Silicide is a silica of transition metals, which can also be used as an intermetallic compound.

The key features of

Hafnium Disilicide Pulver

Hafnium silicide, HfSi2 dust (CAS 12401-56-08) has high melting points, high corrosion resistances, high oxidation resistants, and good electrical conductivity.

The applications

Hafnium Disilicide Pulver

1. Prepare an organic electronic luminescence device. The anode, the light-emitting and cathodes are all included. A packaging cover is stacked in order. The packaging cover protects the light-emitting layers and the cathode of the anode. The packaging cover includes a silicon oxide layer and a barrier layers formed on the silicon carbonitride. The above-mentioned organic electronluminescent device has a very long life span. The invention provides a method to prepare the organic electrodeluminescent device.

2. Preparation of a silicone-germanium alloy-based thermoelectric device. The silicon-germanium alloy-based thermostatic element is composed a silicon-germanium thermoelectric layer, an electrode layer and a silicon–germanium layer-based thermal layer. A barrier layer lies between the electrode and the silicon–germanium layer-based temperatureelectric layer. This barrier layer is made up of silicides and silicon nitride. The silicon-germanium-alloy-based thermoelectric element provided has an excellent combination of interfaces. There are no cracks or visible diffusion phenomena at the interface. It can also withstand long-term high temperatures accelerated tests. Additionally, the provided preparation method is easy to use, cost-effective and reliable. It can also be used for large-scale production.

3. A high temperature, oxidation resistant ceramic composite coating can be prepared. The composition of the composite film is as follows: the coating is made of refractory, refractory, and intermetallic compounds. The coating thickness is 10-50 mm. The refractory metallic is one or many of molybdenum and tantalum as well as zirconium, zirconium, and hafnium. The intermetallic compounds are composed of one or two of molybdenum and tantalum silicides and zirconium carbides. The crystal structure of the coating is made up of non-composition of crystalline or polycrystalline nanoparticles.
