Tantalum carbide upfu, TaC

Ruzivo rwekufungidzira ndi1.44, nzvimbo inonyungudika ndeye 3730-3830 ° C, coefficient yekuwedzera kwekushisa ndeye 8.3 × 10-6, elastic modulus is 291GPa, coefficient of thermal conductivity is 0.22j / cm · S · C.
Zvimiro uye KUSHANDISA
Yakanaka makemikari kugadzikana, isina insoluble mune acids. Yakasimba antioxidant chinzvimbo. TaC inowanzogadzirwa kubva ku tantalum pentoxide uye kabhoni nhema mune inert kana kudzikisira mhepo kuburitsa poda yemhangura.

Zvimiro uye KUSHANDISA
Yakanaka makemikari kugadzikana, isina insoluble mune acids. Yakasimba antioxidant chinzvimbo. TaC inowanzogadzirwa kubva ku tantalum pentoxide uye kabhoni nhema mune inert kana kudzikisira mhepo kuburitsa poda yemhangura. Izvo zvigadzirwa zvine huwandu hwakakura uye esimbi kubwinya kunogona kuitwa nekupisa kudzvanya sintering nzira. Inoshandiswa sechibatanidziro kumuchina weaerospace uye maalloys akaoma.
Tantalum kabhodhi
Hunhu hwe
Chiedza chakajeka chesimbi cubic crystalline poda, ndeyesodium chloride cubic crystal system. Insoluble mumvura, isingasviki mune inorganic acids, inogadziriswa mune yakasanganiswa acids yehydrofluoric uye nitric acids uye inogadziriswa mukuora. Strong oxidation kuramba, nyore kuti fused uye kuora ne potassium pyrosulfate. Kuitisa kwemagetsi kwakakura, iine 30 Ω kuramba pakamuri tembiricha, superconducting zvivakwa.

Inoshandiswa muhupfu hwesimbi, maturusi ekucheka, maceramics akajeka, makemikari emhepo deposition, yakaoma kusakara isingagumi chiwanikwa maturusi, maturusi, mafuru uye kupfeka inodziviririka yehurongwa hwezvinhu zvinowedzeredza, kugadzirisa kuomarara kwesimbi. Iyo sintered muviri we tantalum carbide inoratidza yegoridhe ruvara uye inogona kushandiswa sechishongo chewachi. Tantalum carbide sintered zviyo kukura inhibitor inoshandiswa zvakare kudzivisa kukura kwezviyo, iine huwandu hwe14.3g / cm3.
