(1) Atkar\u012bb\u0101 no s\u016bk\u0146u da\u017e\u0101dajiem tipiem tos var iedal\u012bt centrb\u0113dzes s\u016bk\u0146os ar magn\u0113tisko piedzi\u0146u, zobratu s\u016bk\u0146os ar magn\u0113tisko piedzi\u0146u, skr\u016bves s\u016bk\u0146os ar magn\u0113tisko piedzi\u0146u u. c., no kuriem centrb\u0113dzes s\u016bk\u0146i ar magn\u0113tisko piedzi\u0146u ir galvenais pa\u0161laik izmantoto magn\u0113tisko s\u016bk\u0146u veids;<\/p>\n

Magn\u0113tisk\u0101 s\u016bk\u0146a izol\u0101cijas uzmava liel\u0101koties ir izgatavota no nemagn\u0113tiska met\u0101la vai keramikas materi\u0101la, lai piln\u012bb\u0101 nosl\u0113gtu s\u016bkn\u0113\u0161anas vidi un iek\u0161\u0113jo magn\u0113tisko cilindru.<\/p>\n

Sil\u012bcija karb\u012bda keramikas gult\u0146iem ir liela nestsp\u0113ja, un tie ir \u013coti iztur\u012bgi pret eroziju, \u0137\u012bmisko koroziju, nodilumu un karstumu. Darba temperat\u016bra var sasniegt aptuveni 500 \u00b0C, un kalpo\u0161anas laiks ir sal\u012bdzino\u0161i ilgs, parasti p\u0101rsniedzot 3 gadus.<\/p>\n

Sal\u012bdzinot ar sil\u012bcija karb\u012bda keramikas gult\u0146iem, graf\u012bta gult\u0146iem ir laba pa\u0161sm\u0113r\u0113\u0161an\u0101s un tie var iztur\u0113t \u012bslaic\u012bgu sausu darb\u012bbu. Graf\u012bta gult\u0146i var iztur\u0113t temperat\u016bru l\u012bdz aptuveni 450 \u00b0C, bet to slikt\u0101s nodilumiztur\u012bbas d\u0113\u013c to kalpo\u0161anas laiks ir \u012bs\u0101ks nek\u0101 sil\u012bcija karb\u012bda gult\u0146iem.<\/p>\n
