The Applications of Hafnium Disilicide Powder

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 12401-56-8) 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. It contains an anode and a light-emitting coating, as well as a cathode. The packaging cover protects the light-emitting layers and the cathode of the anode. The packaging cover contains a silicon oxide layer and a barrier. This layer is formed on top of the silicon carbonitride. The organic electroluminescent devices mentioned have a long lifetime. 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 of an electro layer, a silicon/germanium thermoelectric layer and a barrier layer. The barrier layer is composed 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, reliable, low-cost, requires no special equipment and is suitable for large scale production.

3. A high-temperature, oxidation-resistant metal ceramic composite coating is possible. The composition of the composite film is as follows: the coating is composed of intermetallic compound, refractory carbide, and refractory metal. It is approximately 10-50mm thick. 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.
