Ubungqina be-alkali obunokulahlwa bunobuncwane obuphezulu kwaye bulungele izixhobo ezichasayo ezingamiliselwanga ezenziwe ngohlobo lokugalelwa. Ubungqina be-alkali obuchasayo obunokulahlwa buneempawu ezahlukeneyo zokuxhathisa ubushushu obuphezulu, amandla omatshini aphezulu kunye nokumelana nokhukuliseko oluqinileyo lweasidi kuzo zonke iintlobo zeziko kunye nesicelo se-kilns. Ubungqina bealkali obunokulahlwa bunokusabela nge-oxide yesinyithi kubushushu obuphezulu buvelisa iimveliso zolwelo ze-viscosity ephezulu, ezenza umaleko we-glaze ukuthintela ukungena kunye nokhukuliseko lwesinyithi esinyibilikayo sealkali.
Ubungqina be-alkali obuchasayo obunokulahlwa benziwe ngeeaggregates eziphikisayo, izibophelelo kunye nomgubo wokuxhathisa kwealkali. Iiaggregates zayo yiceramsite, umhlaba oncamathelayo oncamathelayo, inkunkuma yeporcelain imathiriyeli, ukomelela okuphezulu kweperlite eyandisiweyo, njl.
Ngokweemeko ezahlukeneyo kunye nokusingqongileyo, ubungqina bealkali obunokulahlwa bunokwahlulwa bube bubungqina bealkali obukhanyayo obunokulahlwa kunye nobungqina bealkali obunzima obunokulahlwa. Ezo zine-porosity enkulu kune-45% zinobungqina bealkali obukhanyayo kwaye abo bane-porosity engaphantsi kwe-45% banobungqina bealkali enzima. Umgangatho onzima wobungqina bealkali obunokulahlwa bunokwahlulwa kubushushu obuphakathi bubungqina bealkali obunokulahlwa kunye nobushushu obuphezulu bealkali ubungqina obunokulahlwa.

I-Refractory alkali proof castable castable isetyenziswa ngokubanzi kwiziko lemizi-mveliso elikhukuliswe zizinto zealkali, ezifana nehovithi ye-onti, inkqubo ye-preheater, isithando somlilo sokubola. Kwaye ingasetyenziswa kule ndawo ilandelayo.
Umzi-mveliso we-RS refractory ngumboneleli ochwephesha othembekileyo wealkali owasekwa ekuqaleni kweminyaka yama-90 yenkulungwane yamashumi amabini. Umzi-mveliso we-RS refractory ukhethekileyo kwii-alkali proof castables iminyaka engaphezu kwama-20. ukuba unemfuno ethile ye-alkali yobungqina obunokulahlwa, okanye unemibuzo malunga nobungqina bealkali echasayo enokuphosa malunga nezalathi zenyama kunye neekhemikhali, nceda uqhagamshelane nathi simahla. kunye ne-Rs refractory factory njengomvelisi wobungqina bealkali obuchwephesha obunokulahlwa eChina, uneengenelo ezithile zokukhuphisana ngolu hlobo lulandelayo:
