Ntau yam lag luam yuav siv rau cov khoom siv tshem plua plav, xws li cov chaw ua smelting, cov chaw tshem plua plav hauv cov chaw ua hlau; kev lag luam metallurgy, kev lag luam mining, kev ntxuav plua plav nrog cov pa roj flue loj; kev ntxuav plua plav hauv kev lag luam tshuaj lom neeg thiab tshuab, thiab lwm yam. Cov yeeb nkab tshem plua plav no feem ntau hnav, qhov hnav ntawm lub luj tshib tsis hnyav, muaj cov tshauv sib sau ua ke, qhov hnav tseem ceeb yog nyob rau sab saud ntawm cov yeeb nkab. Kev hnav yuav ua rau huab cua xau hauv lub cev, cuam tshuam rau kev tswj hwm ntawm qhov chaw plua plav, ua rau lub luag haujlwm ntawm lub cev tshem plua plav puas tsuaj, thiab txawm tias ua rau lub cev tsis ua haujlwm. Rau cov yeeb nkab tshem plua plav siab, kev hnav yuav ua rau lub zog thiab kev tawv ntawm lub luj tshib poob qis, ua rau muaj kev pheej hmoo tsis zoo.
Yog li ntawd, peb yuav tsum tau ua tib zoo saib xyuas qhov puas tsuaj ntawm cov kav dej tshem tawm plua plav thiab tiv thaiv nws kom raws sijhawm. Qhov hnav ntawm lub luj tshib yeeb nkab yog tshwm sim los ntawm kev cuam tshuam ntawm cov hmoov av khov kho rau ntawm phab ntsa. Yog li ntawd, nws yog qhov tsim nyog los ua cov kev ntsuas tiv thaiv kev hnav ntawm phab ntsa sab hauv ntawm cov kav dej. Peb xav kom siv covalumina ceramic uas tsis yooj yim puasNyob rau hauv cov kav dej, cov khoom siv ceramic uas tsis yooj yim hnav zoo heev, tuaj yeem tiv thaiv phab ntsa sab hauv ntawm cov kav dej kom tsis txhob hnav, thiab qhov chaw du, yuav tsis tshwm sim qhov tshwm sim ntawm cov khoom thaiv. Qhov no tuaj yeem ua rau lub neej ua haujlwm ntawm cov kav dej tsawg kawg yog kaum npaug. Cov khoom siv ceramic uas tsis yooj yim hnav tuaj yeem yog qhov kev daws teeb meem zoo rau qhov teeb meem ntawm kev tshem tawm cov plua plav hauv cov kav dej.
