Itara ricandagira ni ubwoko bw'urumuri rw'amashanyarazi rutuma icyuma gishyuha kandi kikarabagirana nyuma y'uko umuraba unyuramo. Itara ricandagira ni isoko y'urumuri rw'amashanyarazi rwakozwe hakurikijwe ihame ry'imirasire y'ubushyuhe. Ubwoko bworoheje bw'itara ricandagira ni ugucisha umuraba uhagije mu cyuma kugira ngo ribe ricandagira, ariko itara ricandagira rimara igihe gito.
Itandukaniro rikomeye riri hagati y’amatara ya halogen n’amatara ashyushye ni uko igikonoshwa cy’ikirahure cy’itara rya halogen cyuzuyemo umwuka wa halogen (ubusanzwe iyode cyangwa bromine), bikora ibi bikurikira: Uko umugozi ushyushye, atome za tungsten zihinduka umwuka zikajya ku rukuta rw’umuyoboro w’ikirahure. Uko zegera urukuta rw’umuyoboro w’ikirahure, umwuka wa tungsten ukonjeshwa kugeza kuri 800°C hanyuma ugahuzwa n’atome za halogen zigakora tungsten halide (iyode ya tungsten cyangwa bromide ya tungsten). Tungsten halide ikomeza kwerekeza hagati mu muyoboro w’ikirahure, igaruka ku muyoboro wa oxidized. Kubera ko tungsten halide ari ikintu kidahindagurika cyane, irashyuha igahinduka umwuka wa halogen na tungsten, hanyuma igashyirwa ku muyoboro kugira ngo ikore imyuka. Binyuze muri ubu buryo bwo kongera gukoresha, igihe cy'imikorere y'urudodo nticyongera gusa (hafi inshuro enye z'itara ry'ingufu), ahubwo nanone kubera ko urudodo rushobora gukora ku bushyuhe bwinshi, bityo rukabona urumuri rwinshi, ubushyuhe bwinshi bw'amabara n'ubushobozi bwo hejuru bw'urumuri.
Ubwiza n'imikorere y'amatara n'amatara y'imodoka bifite akamaro kanini ku mutekano w'ibinyabiziga, igihugu cyacu cyashyizeho amahame ngenderwaho y'igihugu hakurikijwe amabwiriza ya ECE y'i Burayi mu 1984, kandi kumenya imikorere y'amatara ni kimwe mu by'ingenzi muri byo.
