I-Diatomite luhlobo lwelitye le-siliceous, elisasazwa ikakhulu e-China, eUnited States, eJapan, eDenmark, eFransi, eRomania nakwamanye amazwe.Lilitye le-biogenic siliceous sedimentary, eliqulunqwe ikakhulu ziintsalela zediatom zakudala.Ukubunjwa kwayo kweekhemikhali ikakhulu yiSiO2, engabonakaliswa njengeSiO2 · nH2O, kwaye ukubunjwa kwayo kwamaminerali yi-opal kunye neentlobo zayo.Oovimba be-diatomite e-China zizitoni ezizigidi ezingama-320, kwaye abo balindelekileyo bangaphezulu kweetoni ezibhiliyoni ezi-2.

Ubuninzi be-diatomite yi-1.9-2.3g/cm3, ubuninzi be-bulk 0.34-0.65g/cm3, indawo ethile yendawo yi-40-65 ㎡/g, kwaye umthamo wepore ngu-0.45-0.98m ³/ g.Ukufunxwa kwamanzi ngamaxesha angama-2-4 omthamo wawo, kwaye indawo yokunyibilika yi-1650C-1750 ℃.Isakhiwo esikhethekileyo se-porous sinokubonwa phantsi kwe-microscope ye-electron.

I-Diatomite yenziwe nge-amorphous SiO2 kwaye iqulethe ixabiso elincinci le-Fe2O3, i-CaO, i-MgO, i-Al2O3 kunye nokungcola kwezinto eziphilayo.I-Diatomite idla ngokuba ngumthubi okhanyayo okanye ongwevu okhanyayo, othambileyo, omdaka kunye nokukhanya.Ihlala isetyenziselwa kumashishini njengento yokucoca i-thermal, i-filter material, i-filter, i-abrasive material, i-glass yamanzi eluhlaza, i-decolorizing agent, i-diatomite filter aid, i-catalyst carrier, njl. Icandelo eliphambili le-diatomite yendalo yi-SiO2.I-diatomite ephezulu imhlophe, kwaye umxholo we-SiO2 uhlala udlula i-70%.Iidiatom ze-Monomer azinambala kwaye ziyabonakala.Umbala we-diatomite uxhomekeke kwiiminerali zodongwe kunye ne-organic matter, njl. Ukubunjwa kwe-diatomite kwimithombo eyahlukeneyo yamaminerali kuyahluka.

I-Diatomite luhlobo lwefosili ye-diatom eqokelelanayo yediphozithi yomhlaba eyenziwe emva kokusweleka kwesityalo esineseli enye ebizwa ngokuba yi-diatom emva kwexesha lokuqokelelana malunga ne-10000 ukuya kwi-20000 yeminyaka.I-Diatom yenye yeprotozoa yokuqala emhlabeni, ehlala emanzini olwandle okanye echibini.

Le diatomite yenziwa ngokubekwa kweentsalela zesityalo sasemanzini esineseli enye diatom.Ukusebenza okukhethekileyo kwale diatom kukuba inokufunxa i-silicon yasimahla emanzini ukwenza i-skeleton yayo.Xa ubomi bayo buphelile, iya kufaka kwaye yenze iidiphozithi ze-diatomite phantsi kweemeko ezithile ze-geological.Ineempawu ezizodwa, ezifana ne-porosity, i-concentration ephantsi, indawo enkulu yendawo ethile, ukunyanzeliswa kokungahambelani kunye nokuzinza kweekhemikhali.Emva kokutshintsha ukuhanjiswa kobungakanani bamasuntswana kunye neempawu zomhlaba okrwada ngokusila, ukuhlenga, ukubala, ukuhlelwa kokuhamba komoya, ukususwa kokungcola kunye nezinye iinkqubo zokusetyenzwa, kunokusetyenziswa kwiimfuno ezahlukeneyo zoshishino ezifana nezongezo zepeyinti.
