  1. High pure hafnium
    • Appearance and description
      • High purity hafnium is also known as the crystalline hafnium, it is the sliver metal crystal with metallic luster.
    • Product properties
      • It ensures good anti-corrosive property, it is not susceptible to the erosion of acid and alkali solution, soluble in hydrofluoric acid to form a fluoride complexes. At high temperature,hafnium can be directly combined with oxygen, nitrogen and other gases to form the oxide and nitride ;Hafnium is stable in the air, powdered hafnium is easy to burn; the capture cross section of hafnium thermal neutron is large, hafnium with prominent nuclear power, it is indispensable rare materials to develop the atomic energy industry.
    • Application
      • It is mainly for the production of hafnium alloy material, because hafnium has fast endothermic and exothermic performance(1 time faster than zirconium and titanium),thus it can be made the structural material of jet engines and missiles. The refractory of hafnium, making it can be used as the turbojet aircraft vane, used in freezing the point pressure jet engine. Also can be used to make valve, nozzle and other high temperature parts.
  2. Sponge zirconium
    • Appearance and description
      • Zirconium metal is also known as zirconium sponge, it is sliver metal, looks like steel, and it is glossy.
    • Product properties
      • Metal zirconium has strong corrosion resistance, it is not susceptible to the erosion of acid and alkali solution, it is soluble hydrofluoric acid and aqua regia, with ultra high hardness and strength.
    • Application
      • Firearms level zirconium sponge: be used for artillery burners, also can be applied to alloy additives, metallurgical deoxidization, chemical industry, civil flash fireworks, etc.
      • Industrial-grade zirconium sponge: it is mainly used in the production of chemical corrosion resistant equipment, electron industry, Pipeline valve material, Special high strength and high temperature alloy material, electric vacuum and lighting bulb industry getter.
      • Nuclear grade zirconium sponge: it is mainly used in nuclear power plant, nuclear-powered aircraft carrier、structure material and uranium fuel rod cladding material of nuclear reactor in a nuclear submarine、also be used as nuclear reactor core structure material, positioning framework, plug, moderator, etc. It is a kind of important strategic metal.
  3. Sponge hafnium
    • Appearance and description
      • Metal hafnium is also known as sponge hafnium, hafnium is silver metal, with metallic luster.
    • Product properties
      • It ensures good anti-corrosive property, it is not susceptible to the erosion of acid and alkali solution, soluble in hydrofluoric acid to form a fluoride complexes. At high temperature,hafnium can be directly combined with oxygen, nitrogen and other gases to form the oxide and nitride ;Hafnium is stable in the air, powdered hafnium is easy to burn; the capture cross section of hafnium thermal neutron is large, hafnium with prominent nuclear power, it is indispensable rare materials to develop the atomic energy industry.
    • Application
      • Physical condition: hafnium and zirconium look the same, nature is similar, the major difference is that the nuclear properties is quite different, for example, the thermal neutron capture cross section of zirconium is smaller hundreds of times than hafnium. Be used in atomic energy industry and aerospace industry, be used for the control rod material in the nuclear reactor, can be made for the small size and large energy rocket booster.
    • Packaging :
      • Galvanized barrel:the bags lined with double layer plastic pressurized sealing, 20 kg/ barrel 。
      • If the customers have special packaging requirements, we can pack the goods according to customers’ requirements.
  4. Nuclear grade zirconium oxide
    • Appearance and description
      • Zirconium oxide is the main oxides of zirconium, it is the white odorless and tasteless crystal in normal circumstances.
    • Product properties
      • Zirconium oxide is the non-toxic and tasteless white solid, it is poorly soluble in water, hydrochloric acid and dilute sulphuric acid (except hot H2SO4、HF and H3PO4) ;they are chemically inert, its excellent properties is high-melting point, high resistivity, low heat expansion coefficient, so it has a wide range of end-uses.
    • Application
      • Metal zirconium and its compound material.
      • Domestic ceramics, refractory material; zirconium brick, zirconium tube, crucible, etc ( for precious metal smelting).
      • Thermal barrier coating for aerospace and industrial gas turbine;
      • Zirconium oxide can also be used as polishing agent, abrasive grain, piezoelectric ceramics, precision ceramics, the host materials of ceramic glaze and high temperature pigment, X-ray radiography, can also be made for the light lamp of infrared absorbance, also it is the main raw material of artificial diamond.
  5. Nuclear grade hafnium oxide
    • Appearance and description
      • Hafnium oxide is the main oxides of hafnium, it is the white odorless and tasteless crystal in normal circumstances.
    • Product properties
      • Hafnium oxide is a kind of non-toxic and tasteless white solid, not dissolve in water, hydrochloric acid and nitric acid, be soluble in concentrated sulfuric acid and hydrogen fluoride acid; They are chemically inert, with thin film properties: transparent range~220~12000nm; refractive index(250nm)~2.15 (500nm)~2, with high melting point, so it has a wide range of end-uses.
    • Application
      • Metal hafnium and its compound materials
      • Refractory materials, anti-radiation coatings and special catalyst
      • High strength glass coating.
  6. Zirconium tetrachloride
    • Appearance and description:
      • Zirconium tetrachloride is white shiny crystal or powder, it is highly deliquescent.
    • Product properties:
      • Solubility: Be soluble in water, ethanol, diethyl ether, insoluble in benzene, carbon tetrachloride, carbon disulfide.
      • Zirconium tetrachloride will be smoke in the damp air,it will be Strong hydrolysis when wet,hydrolysis is not completely, the hydrolyzate is zirconium oxychloride: ZrCl4+H2O─→ZrOCl2+2HCl
    • Application:
    • Be used as analytical reagent, organic synthesis catalyst, waterproofing agent, tanning agent, also it is material for producing metal zirconium in the industry.
