Overview of Hafnium Carbide HfC Powder:
Hafnium carbide (HfC) is a compound of carbon and hafnium.Its melting point is about 3900°C,which is one of the most refractory binary compounds known.However, its oxidation resistance is very low,and oxidation starts at temperatures as low as 430°C.
Hafnium carbide is a black,gray,brittle solid;high cross-section absorbs thermal neutrons;resistivity 8.8μohm·cm;the most refractory binary material known;hardness 2300kgf/mm2;used in nuclear reactor control rods;It is prepared by heating HfO2 with oil soot under H2 at 1900°C-2300°C.It is used in the form of the crucible to melt oxide and other oxides.
An improved spark plasma sintering (SPS) device was used to synthesize ultrafine carbonized ha powder through the carbothermal reduction reaction of HfO2 at 1600°C.The synthetic powder has a fine particle size of about 125 nm and low oxygen content of less than 0.5% by weight.Except for Zr,the powder purity is> 99.9%;when it contains Zr impurities,the powder purity is 99.6%.Due to the low synthesis temperature,rapid heating/cooling rate and the current influence during the improved SPS process,intermediate reactions and particle growth are minimized.A relatively large amount of HfC powder can be synthesized by a new synthesis method (>175 g/day).After sintering the synthesized powder by SPS at 2300°C for 30 minutes under a pressure of 100 MPa,HfC ceramics with high relative density (>96%) were obtained.Feel free to send an inquiry to get the latest price if you would like to buy Hafnium Carbide HfC Powder in bulk.
