What is ZrC powder?
Zirconium carbide is a kind of high melting point material with high hardness and excellent high temperature refractory. Used as a raw material for solid propellant in rocket engines.Used to produce alloy steel. It is also a raw material for the production of zirconium metal and zirconium tetrachloride, as well as promising fine ceramic materials.
ZrC powder synthetic method
Use berkelium oxide and charcoal as raw materials. Mix the two, put them into graphite crucible of carbonization furnace, heat in a hydrogen atmosphere to 2400ºC, make it react, then produce zirconium carbide. Zirconia and carbon black can also be fully mixed, pressurized molding, in the induction graphite crucible, also heated to 1800ºC in a hydrogen atmosphere, adding 1% ~ 2% carbon black, and then annealing in vacuum at 1700 ~ 1900ºC, that is, zirconium carbide. Or zirconia and magnesium metal as raw materials, mix the two, into a recyclable reactor, continuous methane gas, and temperature to 750ºC, and hydrochloric acid pickling to remove the by-products, zirconium carbide.
Auxiliary metal bath method. Cobalt was used as the auxiliary metal, and the metal bath was composed of zirconium and cobalt, which were added to the graphite crucible in a ratio of 1:6, covered with graphite powder, and heated in a Taman furnace with hydrogen as the protective gas. The temperature was rapidly increased to 1500℃ within 5 minutes, and then to 2000℃ within 15 minutes. The temperature was maintained for 30 minutes, and then cooled to room temperature for 2 hours. The product of the reaction is crushed and treated with hot hydrochloric acid to dissolve the cobalt. Excess graphite is separated by hydrofluoric acid treatment.
Gas reaction method. Zirconium tetrafluoride vapor and hydrocarbon (methane, benzene, etc.) gas with hydrogen mixed evenly, through the direct electrical heating to 1700 ~ 2400℃ tungsten wire, so that the reaction, you can precipitate zirconium carbide, its crystal morphology with different reaction conditions and different.
ZrC powder application
Zirconium carbide is an important high-temperature structural material with a high melting point, high strength, and corrosion resistance. It can be used as an electrode, the refractory crucible, and cathode electron emission material. Used in multiple alloys to improve mechanical strength, but also the production of metal zirconium, zirconium tetrachloride raw materials.
Used for multiple alloys to improve mechanical strength, it is an important intermediate product for preparing zirconium from zirconium ore and is also the raw material for producing zirconium metal and zirconium tetrachloride. Zirconium carbide ceramics are used for power supply, heat crucible, and cathode electron luminescence materials.
