Thaethaniamo diboride
CAS: 12045-63-5
Matlotlo:
qhibiliha ntlha: 2900-3225 ° C
segokanyipalo; 4.52 g / ml ka 25 ℃ (hotetsa)
e tiile ka peroxide ea hydrogen le acid e sulfuric
thepa ea lik'hemik'hale:

Sehlahisoa sena ke kristale e bohlooho e mahlakore a tšeletseng e nang le letsoalo le lekanang la 4.50 le ntlha e qhibilihisang 2900 ℃. E na le thatafalo e phahameng le matla, e ntle mocheso ho hanyetsa, ho hanyetsa motlakase o tlase ebile ha ho bonolo ho senngoa ke tšepe e qhibilihisitsoeng.

Phofo e sebelisoa ka rokete nozzle, ho ikopanya le motlakase le phahameng mocheso lintho tse bonahalang eleketrode, hape e ka sebelisoa e le khorofo .; li-ceramics tse tsamaisang thepa, lisebelisoa tsa letsopa, ts'ebeliso e sa sebetseng ea ho roala V ts'ebeliso thepa conductive le likarolo tse ngata. conductive boron nitride (steamboat), E hlahisitsoeng ka titanium diboride (TiB2) le boron nitride (BN), ke karolo ea mantlha ea lisebelisoa tsa alumine e hloekisang. Lisebelisoa tsa ho itšeha ka letsopa le likarolo. Li-ceramics tsa thaethaniamo diboride li etsoa bakeng sa lefu la ho taka terata, extrusion ea shoa, lisepa tsa sandblasting, likarolo tsa ho tiisa, lisebelisoa tsa ho itšeha, jj. Titanium diboride e ka sebelisoa e le karolo ea bohlokoa ea lisebelisoa tsa likarolo tse ngata. Titanium diboride e ka sebelisoa e le sesebelisoa sa ho itšeha k lisebelisoa tse kopaneng tse nang le tic, tin, SiC le lisebelisoa tse ling. E ka sebelisoa hape e le karolo ea ho etsa thepa ea ts'ireletso ea lihlomo. Ke lisebelisoa tse ntlehali bakeng sa likarolo tse fapaneng tsa mocheso o phahameng le lisebelisoa tse sebetsang. Lisebelisoa tsa Cathode tsa aluminium electrolysis.

E ka sebelisoa e le lisebelisoa tsa cathode tsa sele ea phokotso ea aluminium, TiB2 e na le mongobo o motle o nang le aluminium e qhibilihisitsoeng, e fokotsang ts'ebeliso ea matla ea aluminium ea elektrolytic mme e lelefatsa bophelo ba sele ea elektrolytic.

E ka etsoa hape ka lisebelisoa tsa ho futhumatsa tsa PTC le lisebelisoa tse fetohang tsa PTC, e leng moemeli ea matlafatsang oa A1, Fe, Cu le lisebelisoa tse ling tsa tšepe. Kopo: e sebelisoa e le nozzle ea rocket, ho ikopanya le motlakase, thepa ea eleketrode; Mokhoa oa boron carbide, o tsejoang hape e le mokhoa oa phokotso ea carbothermal, o ka lokisoa ka ho sebelisa TiCl4 le BCl3 e le lisebelisoa tse tala, tlasa boemo ba H2, mocheso oa phepelo ke 800 ~ 1000 ℃, TiCl4 + 2bcl3 + 5h2 = TiB2 + 10hcl, ts'ebeliso ea siloa le lihlahisoa tsa boemo ba motlakase.
