Sebopi sa elektrone sa Tungsten,
Lithunya tsa Tungsten E-Beam
Li-liner tse hloekileng tsa tungsten (W), tse sebelisetsoang mohloli oa mahlaseli a elektrone, mocheso o sebetsang ho fihlela ho 2400℃. Khanyetso ea mocheso o phahameng, le khanyetso ea mafome, li ka thibela ka katleho tšilafalo e ka bang teng ea ho roala nakong ea ts'ebetso ea ho roala.
Re fana ka li-liner tse hloekileng tsa tungsten tsa 4cc, 7cc, 15cc, 25cc, 30cc, 40cc, le 100cc, tse loketseng lisebelisoa tsa mouoane oa mahlaseli a elektrone, ebang ke mohloli oa mahlaseli a elektrone a pokotho e le 'ngoe kapa lipokotho tse ngata tse ka kenngoang le ho sebelisoa.
Li-liner tsa rona tsa tungsten crucible li fana ka bohloeki bo phahameng, ho hanyetsa mocheso o phahameng, le ho hanyetsa ho thekesela le ho bola ho babatsehang. Ka hona, nako ea mouoane e ka khutsufatsoa, bophelo ba ts'ebeletso bo ka lelefatsoa, 'me litšenyehelo tsa tlhahiso li ka bolokoa.
Theknoloji ea mouoane oa mahlaseli a elektrone e ka fihlella mocheso o phahameng haholo, e leng se lumellang sekhahla se potlakileng sa ho beoa le mefuta e mengata ea thepa ho mouoane. Thepa e lokelang ho mouoane (evaporator) e beoa ka har'a sebōpi se ka har'a onto, e futhumatsoe ebe e mouoane ka har'a onto, ebe e beoa holim'a substrate ho etsa filimi e hlokahalang.
Tungsten e na le ntlha e phahameng ea ho qhibiliha le ho belisa, matla a matle a mocheso o phahameng, ho hanyetsa ho tsofala le ho hanyetsa ho bola, ho khanna mocheso o phahameng, coefficient e nyane ea katoloso ea mocheso, le ho tiea ho hotle. Li-crucible tsa Tungsten li sebelisoa haholo ho qhibilihiseng ha lefatše le sa tloaelehang, khalase ea quartz, ho fafatsa ka elektroniki, kholo ea kristale le liindasteri tse ling.

• Khetho ea phofo ea tungsten ea boleng bo holimo ho netefatsa bohloeki.
• Tlhahiso ea litsebi, boholo bo nepahetseng ba sehlahisoa, bokaholimo bo khanyang.
• Theknoloji e utloahalang, nako e khutšoanyane ea ho tlisa thepa le theko e khethehileng.
• E etselitsoe ho latela litšoantšo, esita le likotoana tse peli li ka hlahisoa.
Ka boiphihlelo ba lilemo tse fetang leshome, re ka hlahisa li-crucible tsa Tungsten tse nang le bongata bo phahameng haholo le bohloeki, litekanyo tse nepahetseng, bokaholimo bo boreleli le khanyetso e ntle ea ho thekesela.
Li-crucible tsa rona tsa tungsten li sebelisoa ke bareki ba bangata lefatšeng ka bophara ka katleho e kholo. Ebang ke sebopi se senyenyane bakeng sa tšebeliso ea laboratori (bophara ba 10mm) kapa sebopi se seholo bakeng sa tšebeliso ea indasteri (bophara ba 300mm), re ka khotsofatsa tlhoko ea hau.
