Isi ya Diatomaceous ni ubwoko bw'ibuye rya siliceous rikunze kuboneka mu bihugu nka Ubushinwa, Leta Zunze Ubumwe za Amerika, Ubuyapani, Danemark, Ubufaransa, Rumaniya, n'ibindi. Ni ibuye rya siliceous sedimentary rigizwe ahanini n'ibisigazwa bya diatoms za kera. Ibigizemo ubutabire ahanini ni SiO2, ishobora guhagararirwa na SiO2 · nH2O, kandi imiterere yaryo y'amabuye y'agaciro ni opal n'ubwoko bwayo. Ubutaka bwa diatomaceous bushobora kuboneka mu Bushinwa bungana na toni miliyoni 320, hamwe n'ububiko bushobora kuboneka bungana na toni zisaga miliyari 2, ahanini buherereye mu Burasirazuba bw'Ubushinwa no mu Majyaruguru y'Uburasirazuba bw'Ubushinwa. Muri zo, Jilin (54.8%, hamwe n'Umujyi wa Linjiang mu Ntara ya Jilin ari wo wa mbere wagaragaye ko uboneka muri Aziya), Zhejiang, Yunnan, Shandong, Sichuan, n'izindi ntara zifite ahantu henshi hakwirakwizwa, ariko ubutaka bwiza buboneka gusa mu gace k'umusozi wa Changbai muri Jilin, kandi andi mabuye menshi y'agaciro ni ubutaka bwo mu cyiciro cya 3-4. Kubera ko bufite umwanda mwinshi, ntibushobora gutunganywa no gukoreshwa mu buryo butaziguye. Igice cy'ingenzi cy'isi ya diatomaceous nk'umutwaro ni SiO2. Urugero, igice gikora cya vanadium catalyst ni V2O5, co catalyst ni alkali metal sulfate, naho catalyst ni diatomaceous earth itunganijwe neza. Ubushakashatsi bwagaragaje ko SiO2 igira ingaruka nziza ku bice bikora kandi ikiyongera uko ingano ya K2O cyangwa Na2O yiyongera. Imikorere ya catalyst nayo ifitanye isano n'uburyo ikwirakwira n'imiterere y'imyobo y'imyobo. Nyuma yo kuvura aside ya diatomaceous earth, ingano y'imyanda ya oxyde iragabanuka, ingano ya SiO2 iriyongera, kandi ubuso bwihariye n'ingano y'imyobo nabyo biriyongera. Kubwibyo, ingaruka z'imyobo ya diatomaceous earth itunganijwe neza ni nziza kuruta iz'imyobo karemano ya diatomaceous earth.

Ubusanzwe ubutaka bwa Diatomaceous bukorwa mu bisigazwa bya silicate nyuma y’urupfu rw’uturemangingo tw’ibinyabuzima, tuzwi cyane nka diatoms, kandi ishingiro ryabyo ni SiO2 idahinduka amazi. Diatoms zishobora kubaho haba mu mazi meza no mu mazi y’umunyu, hamwe n’ubwoko bwinshi. Muri rusange zishobora kugabanywamo diatoms “zo hagati” na diatoms “zo mu mababa”, kandi buri bwoko bufite “genera” nyinshi zigoye cyane.

Igice cy'ingenzi cy'ubutaka bw'ibimera ni SiO2, aho ubwazo bufite ibara ry'umweru kandi ingano ya SiO2 ikunze kurenza 70%. Diatome imwe nta ibara ifite kandi ibonerana, kandi ibara ry'ubutaka bw'ibimera riterwa n'imyunyu ngugu y'ibumba n'ibintu bikomoka ku bimera. Imiterere y'ubutaka bw'ibimera bikomoka ku bimera bitandukanye iratandukanye.

Isi ya Diatomaceous, izwi kandi nka diatom, ni ikigega cya diatom cyakozwe nyuma y’urupfu rw’ikimera kimwe cyapfuye, kikaba cyaramaze imyaka iri hagati ya 10000 na 20000. Diatoms zari zimwe mu binyabuzima bya mbere byagaragaye ku Isi, ziba mu mazi y’inyanja cyangwa mu mazi y’ikiyaga.

Ubu bwoko bw'ubutaka bwa diatomaceous bukorwa no gushyira ibisigazwa by'ibimera byo mu mazi bifite akaremangingo kamwe. Imikorere yihariye y'iyi diatomaceous ni uko ishobora kwinjiza silikoni mu mazi kugira ngo ikore amagufwa yayo. Iyo ubuzima bwayo burangiye, ishyira kandi ikarema ibisigazwa by'ubutaka bwa diatomaceous munsi y'imiterere runaka ya geologi. Ifite imiterere yihariye, nko gutobora, ubucucike buke, ubuso bunini bwihariye, kudakomera, no kudahindagurika kwa shimi. Nyuma yo guhindura ingano y'uduce n'imiterere y'ubuso bw'ubutaka bw'umwimerere binyuze mu buryo bworoshye.Uburyo bwo gupima nko gusya, gutondeka, gukaranga, gushyira mu byiciro umwuka utemba, no gukuraho umwanda, bushobora kuba bwiza ku bintu bitandukanye bikenewe mu nganda nko gusiga irangi n'ibindi bikoresho byo gusiga amarangi.
