What is HfC powder?
Hafnium carbide (HfC), a gray solid with a metallic luster, has the highest melting point among known single compounds and is a good material for the lining of melting crucible of high melting point metals. It has excellent characteristics such as a high melting point, hardness, high-temperature strength, good corrosion resistance, low thermal conductivity, etc. It can be used as an additive of hard Chemicalbook alloy and is widely used in cutting tools and dies. It is also suitable for rocket nozzle materials, can be used in the nose cone of rockets, is often used in the aerospace field, and can also be used in the nozzle, high-temperature resistant lining, and electrode for electric arc or electrolysis. It can also be used for control rods of nuclear reactors.

 


 
What is HfC powder used for?
The main purpose of hafnium is to make control rods for atomic nuclear reactors. Pure hafnium is important in the atomic energy industry because of its plasticity, easy processing, high-temperature, and corrosion resistance. Hafnium is an ideal neutron absorber because of its large thermal neutron capture cross-section, which can be used as a control rod and protection device for atomic reactors. Hafnium powder can be used as a rocket propeller. The cathode of an X-ray tube can be manufactured in the electrical appliance industry. Hafnium alloy can be used as the front protective layer of rocket nozzle and gliding reentry aircraft, and Hf-Ta alloy can be used to make tool steel and resistance materials. Hafnium is an additive element in heat-resistant alloys, such as tungsten, molybdenum, and tantalum. HFC can be used as cemented carbide additive because of its high hardness and melting point. The melting point of 4 tac HFC is about 4215, the highest known compound.

Chemical properties of HfC powder
And hafnium and carbon as the main components. Hafnium carbide (HfC) has the highest melting point among known single compounds. The volume resistivity is 1.95× 10-4 Ω cm (2900), and the thermal expansion coefficient is 6.73×10-6/. Usually, hafnium dioxide (HfO2) and carbon are synthesized into powder in an inert or reducing atmosphere, and the reaction temperature is 1900 ~ 2300. High-density ceramic desserts are prepared by hot pressing sintering or hot isostatic pressing. Hafnium carbide can form a solid solution with many compounds (such as ZrC, TaC, etc.). For example, the composite carbide of HfC-4TaC has two phases in microstructure: one phase is hafnium carbide-tantalum carbide eutectic; The other phase is acicular free graphite phase with a shape ratio of 50: 1. This "near eutectic" hafnium carbide (HfC) product has good thermal stability and high melting point. It can be used as a throat material for rocket nozzles. Density: 12.7 Melting point: 3890
