Lapho kushisa, ukungcola kwe-inorganic kusampula kuzinzile (njenge-sodium chloride, i-potassium chloride, i-sodium sulfate, njll.), uma kungenjalo ngenxa yokushiswa nokuhwamuka, le ndlela ingasetshenziswa ukucacisa umlotha osesampula.

[Indlela Yokunquma] Faka ikhava ye-ceramic crucible (noma i-nickel crucible) esithandweni sikagesi esinezinga lokushisa eliphezulu (okungukuthi, isithando somlilo) noma ilangabi legesi, lishise libe isisindo esingaguquki cishe (cishe ihora elingu-1), liyise endaweni yokomisa i-calcium chloride. futhi kuphole ekamelweni lokushisa. Isivalo se-crucible sabe sesikalwa ndawonye kubhalansi yokuhlaziya futhi sasethwa ku-G1 g.

Ngo crucible kakade enesisindo, thatha isampula efanele (kuye ngokuthi umlotha isampula, ngokuvamile ebizwa ngokuthi 2-3 amagremu), wathi 0.0002 amagremu, umlomo crucible lid cishe izingxenye ezintathu kwezine, ngomlilo ongaphakeme kancane bafudumale crucible, wenze isampula kancane kancane carbonization. , ngemva kwe-crucible esithandweni sikagesi (noma ilangabi legesi), hhayi ngaphansi kuka-800℃ukusha kuze kufike esisindweni esingaguquki (cishe amahora ama-3), kuthuthelwe endaweni yokomisa i-calcium chloride, epholile ekamelweni lokushisa, enesisindo. Kungcono ukushisa emva kwamahora angu-2, upholile, ulinganise, bese ushisa ihora elingu-1, bese upholile, ulinganise, njengesisindo esiphindwe kabili ngokulandelana, isisindo cishe asishintshiwe, kusho ukuthi kushiswe ngokuphelele, uma isisindo sincishiswa. ngemva kokushiswa kwesibili, khona-ke kufanele kube ukushiswa kwesithathu, ukushisa kuze kufane nesisindo esingaguquki, setha ama-G amagremu.

(G-G1) / isisindo sesampula x100= grey%

[Qaphela] - -Usayizi wesampula unganqunywa ngokuya ngenani lomlotha kusampula, isampula lomlotha omncane, lingabizwa cishe ngamagremu angu-5 wesampula, isampula lomlotha omningi, lingabizwa cishe ngamagremu angu-2 wesampula.

2. Isikhathi sokushiswa sincike esisindweni sesampula, kodwa ukushisa kufana nesisindo esingaguquki.

3. Umehluko wesisindo osha kabili ngokulandelana bekungcono ube ku-0.3 mg ngezansi, umehluko omkhulu awukwazi ukudlula i-1 mg, bheka njengokulinganiselwa kwesisindo esingaguquki okungukuthi.
