Kulinganiselwa ukuthi ukukhishwa komhlaba wonke kwezinto eziphikisayo sekufinyelele cishe ku-45×106t ngonyaka, futhi kuye kwagcina ukuthambekela okukhuphukayo unyaka nonyaka.
Imboni yensimbi iseyimakethe eyinhloko yezinto eziphikisayo, idla cishe u-71% womkhiqizo wonyaka we-refractory. Eminyakeni eyi-15 eyedlule, ukukhiqizwa kwensimbi engahluziwe emhlabeni kuphindeke kabili, kwafinyelela ku-1,623×106t ngo-2015, okungama-50% akhiqizwa eChina. Eminyakeni embalwa ezayo, ukukhula kukasimende, izitsha zobumba kanye neminye imikhiqizo yezimbiwa kuzohambisana nalo mkhuba wokukhula, futhi ukwanda kwezinto eziphikisayo ezisetshenziswa ekukhiqizweni kwemikhiqizo yezimbiwa zensimbi nezingeyona eyensimbi kuzoqhubeza nokugcina ukukhula kwemakethe. Ngakolunye uhlangothi, ukusetshenziswa kwezinto eziphikisayo kuzo zonke izindawo kuyaqhubeka nokuncipha. Kusukela ngasekupheleni kwawo-1970, ukusetshenziswa kwekhabhoni sekugxilwe kuyo. Izitini eziqukethe i-carbon ezingashisiwe zisetshenziswe kakhulu emikhunjini yokwenza insimbi nensimbi ukuze kuncishiswe ukusetshenziswa kwezinto eziphikisayo. Ngesikhathi esifanayo, ama-Castables aphansi kasimende aqala ukufaka esikhundleni sezitini eziningi ezingezona i-carbon refractory. Izinto eziphikisayo ezingenakulinganiswa, njengezinto ezikhandwayo kanye nezinto zokujova, azizona nje ukuthuthukiswa kwezinto ngokwazo, kodwa futhi nokuthuthukiswa kwendlela yokwakha. Uma kuqhathaniswa nolwelwesi oluphikisayo olungabunjiwe lomkhiqizo onobunjwa, ukwakhiwa kuyashesha futhi isikhathi sokunciphisa iziko siyancishiswa. Inganciphisa kakhulu izindleko.
Ama-refractories angabunjwanga enza ama-50% emakethe yomhlaba, ikakhulukazi amathuba okukhula kwama-castable kanye nama-preforms. E-Japan, njengomhlahlandlela wenkambiso yomhlaba wonke, ama-monolithic refractories asevele athatha u-70% wesamba somkhiqizo we-refractory ngo-2012, futhi isabelo sabo semakethe siqhubekile nokukhula.
