BORSERKUNI

BORSERKUNI, ravandi korkardi kimiyoiyu harorati, ser gardondani sathi filizzu khulaho bo unsuri bor va dar vaqti garmkuni va dar muhiti faoli kimiyoi nigoh donshtan. Borserkuniro bo maqsadi ziyod namudani sakhti, garmitobovari va ba khurdashavi tobovar shudan meguzaronand. Borserkuni inchunin ba zangzani tobovar shudani khulahoi ohani dar muhithoi gunoguni faol va garmitobovariro dar harorati pasttar az 850°S tamin menamoyad. Borserkuni bo tarz va usulhoi gunogun anjom doda meshavad. Dar sanoat Borserkuni bo usuli mahlulhoi khoka, elektroliz, elektrolizi bemoe, ioni va molidani hamiraho amali megardad. Le­kin aksar vaqt Borserkuni dar elektrolizi borati gudokhta (N₂B₄O₇, tetraborati natriy) anjom doda meshavad. Dar in ravand masoleh chun katod va grafit chun anod khidmat mekunad. Dar harorati 930-950°S va muhlati 2-6 soat masoleh ba qabati az bor sershudai 0,15-0,25 mm sohib meshavad (qabati beruna az FeV, dokhili az Fe₂V). Borserkuniro dar vaqti rekhtani masoleh niz anjom dodan mumkin ast. Dar in holat ba sathi qolabi rekhtagari qabati makhsusi khamirai az bor sershudaro memoland. Chunin khamiraho hangomi pukhtan dar kura ba sathi masoleh molida meshavand. In tarzi Borserkuni bo samaranoki va sodagiash farq mekunad. Pas az Borserkuni ustuvorii masoleh 2-10 bor va garmitobovariash to 900-950°S meafzoyad. Sakhtii qabati bo bor sershuda dar pulodi perliti 15000-20000 MPa-ro tashkil medihad.
