Okukhona ubukhulu besuntswana buncinci, kokukhona ubumhlophe buphezulu. Okukhona ubukhulu besuntswana buqina, kokukhona kunzima ukususa ikhabhoni, ingakumbi ikhabhoni engaphakathi kwesuntswana akulula ukuyitshintsha, nto leyo echaphazela ubumhlophe bemveliso efakwe i-calcium. Izinto ezikrwada zilungile, indawo yomphezulu inkulu, ikhabhoni kulula ukuyisusa, ikhabhoni kulula ukuyitshintsha, kwaye ubumhlophe bemveliso efakwe i-calcium buphezulu.

Kwinkqubo yokulungisa ubumhlophe bemveliso, i-kaolin inesantya esicothayo ngokunyuka kobushushu be-calcination. Xa kuthelekiswa ne-900 ℃, i-850 ℃ ye-calcination ye-kaolin, iimveliso ze-kaolin azisusi nje kuphela amanzi ekristale, zonyusa ubungakanani be-pore, kodwa zigcina ubumhlophe obuqhekekileyo, obuhambelana nobushushu be-calcination, zinciphisa iindleko zotyalo-mali kunye nongcoliseko lokusingqongileyo, ngoko ke i-850 ℃ yeyona qondo lobushushu be-calcination lilungileyo.

Ubumhlophe bemveliso buyanda ngexesha lobushushu obungaguqukiyo, kodwa umkhwa ucotha. Xa ubushushu bufutshane kakhulu, ikhabhoni kwi-kaolin akulula ukuyisusa. Emva kweeyure ezingaphezu kwezi-4 zobushushu obungaguqukiyo, inqanaba lokususwa kwekhabhoni kunye nokuphelelwa ngamanzi emzimbeni kwemveliso lincinci, ngoko ke ubumhlophe bemveliso buyaphucuka, kodwa ukuphucuka kuncinci kakhulu. Ukuze kuphuculwe ukusebenza kakuhle kobushushu, ulawulo lobushushu oluhlala luhleli lwemveliso ene-calcium lufanelekile ngakumbi iiyure ezi-4.

Ngokusebenzisa izongezo ezahlukeneyo ze-calcining, inkqubo yemveliso yenziwa lula, iindleko ziyancitshiswa, kwaye ubumhlophe beemveliso ze-calcined buphucuka kakhulu. Phakathi kwazo, i-sodium chloride sesona songezo sisebenzayo. Ukungeniswa kwe-urea njenge-intercalation agent kwandisa ubumhlophe be-calcined kaolin.

Ulawulo lwemozulu ye-calcination lunempembelelo enkulu kubumhlophe kunye nobutyheli beemveliso ze-calcined. Ukuze kuhlangatyezwane neemfuno zokususwa kwekhabhoni ye-kaolin yamalahle, i-calcination kwimozulu ye-oxidizing ibangela i-oxide yentsimbi ephantsi kunye nexabiso eliphezulu, nto leyo eya kukhokelela ekwandeni kokususwa kwekhabhoni kunye nobutyheli beemveliso ze-kaolin. Ke ngoko, i-calcination kwi-850 ℃ kubushushu obuphezulu kunye nomoya ophantsi kunokunciphisa i-iron ephantsi kunye ne-iron ephezulu, kulawule umoya we-calcination, kunciphise ubumhlophe kwaye kuphucule ubutyheli beemveliso.
