Sepheo sa titanium diboride ke eng?

Sepheo sa Titanium diboride e entsoe ka titanium diboride. Titanium diboride ke ntho e 'mala o moputsoa kapa o moputsoa o nang le sebopeho sa kristale sa hexagonal (AlB2), sebaka se qhibilihang se fihlang ho 2980 ° C, boima ba 4.52g/cm³, le microhardness ea 34Gpa, kahoo e thata haholo.ess. E na le oximocheso oa ho hanyetsa mocheso oa ho fihla ho 1000 ℃ moeeng, 'me o lula o tsitsitse ho HCl le HF acids, ho bontša ho hanyetsa ho bola ha asiti.Lisebelisoa tsa thepa ke tse latelang: coefficient ea ho atolosa mocheso: 8.1 × 10-6m / m · k; Thermal conductivity: 25J / m · s·k; Ho hanyetsa: 14.4μΩ · cm;

Thepa ena e boetse e na le conductivity e ntle ea mocheso le motlakase, ka hona e sebelisoa haholo libakeng tse fapaneng tsa indasteri, joalo ka vacuum coating, lisebelisoa tsa ho itšeha ka ceramic le hlobo, crucible e phahameng ea mocheso, likarolo tsa enjene joalo-joalo. Ka nako e ts'oanang, sepheo sa titanium diboride e boetse e le sepheo sa bohlokoa bakeng sa ho lokisoa ha li-alloys tsa titanium, li-ceramics tse thata tse phahameng le ho matlafatsa konkreite.

 Mokhoa oa ho hlahisa sepheo sa titanium diboride?

Mokhoa oa 1.Direct synthesis: Mokhoa ona ke ho kopanya ka ho toba titanium le phofo ea boron ka mocheso o phahameng oa mocheso ho hlahisa titanium diboride. Leha ho le joalo, mocheso oa karabelo ea mokhoa ona o hloka ho feta 2000℃, theko ea thepa e tala e phahame, mokhoa ona ha o bonolo ho o laola, karabelo ha e phethehe, TiB2 e hlahisoang e tlaase ka bohloeki, 'me ho bonolo ho hlahisa TiB, Ti2B le metsoako e meng.

2.Mokhoa oa Borothermal: Mokhoa ona o sebelisa TiO2 (bohloeki bo phahameng ho feta 99%, sebopeho sa ase, boholo ba likaroloana 0.2-0.3μm) le amorphous B (bohloeki ba 92%, boholo ba likaroloana 0.2-0.3μm) e le lisebelisoa tse tala, ka karolelano e itseng le mokhoa oa ho sila bolo (hangata o etsoa tlas'a vacuum), ka mocheso oa karabelo o sa feteng 1100 ° C ho lokisa titanium. diboride.

3.Ho qhibiliha electrolysis: Ka mokhoa ona, li-oxide tsa titanium li sebetsana le borate ea tšepe ea alkali (kapa alkaline) le fluorates tlas'a maemo a ho qhibiliha ha electrolysis ho etsa titanium dib.oride.
E 'ngoe le e' ngoe ea mekhoa ena ea tlhahiso e na le litšobotsi tsa eona, khetho e khethehileng ea ts'ebetso e itšetlehileng ka tlhokahalo ea tlhahiso, maemo a thepa le litšenyehelo tsa moruo le lintlha tse ling.

Ke likarolo life tsa ts'ebeliso ea sepheo sa titanium diboride?
