Isi ya Diatomaceous ni ubwoko bwurutare rwa silisike ikwirakwizwa cyane mubihugu nku Bushinwa, Amerika, Ubuyapani, Danemark, Ubufaransa, Rumaniya, nibindi.Ibigize imiti ahanini ni SiO2, ishobora guhagararirwa na SiO2 · nH2O, kandi imyunyu ngugu ni opal nibindi bitandukanye.Ububiko bw’ubutaka bwa diatomace mu Bushinwa ni toni miliyoni 320, hamwe n’ububiko bwa toni zirenga miliyari 2, ahanini bukaba bwibanda mu Bushinwa bw’Uburasirazuba n’Amajyaruguru y’Ubushinwa.Muri bo, Jilin (54.8%, hamwe n'Umujyi wa Linjiang mu Ntara ya Jilin niwo ubarizwa mu bubiko bwa mbere bwagaragaye muri Aziya), Zhejiang, Yunnan, Shandong, Sichuan, n'izindi ntara zifite ikwirakwizwa ryinshi, ariko ubutaka bwo mu rwego rwo hejuru bwibanda gusa muri Agace k'imisozi ya Changbai ya Jilin, hamwe nandi mabuye y'agaciro ni ubutaka bwa 3-4.Bitewe nibirimo byinshi byanduye, Ntishobora gutunganywa no gukoreshwa neza.Ibice byingenzi bigize isi ya diatomaceous nkabatwara ni SiO2.Kurugero, ibice bigize catalizike ya vanadium yinganda ni V2O5, co cataliste ni alkali ibyuma bya sulfate, kandi uyitwaye ni isi itunganijwe neza.Ubushakashatsi bwerekanye ko SiO2 igira ingaruka zihamye kubintu bikora kandi ikiyongera hamwe no kwiyongera kwa K2O cyangwa Na2O.Igikorwa cya catalizator nacyo kijyanye no gutatanya hamwe nimiterere ya pore yabatwara.Nyuma yo kuvura aside kwisi ya diatomaceous, ibirimo umwanda wa oxyde bigabanuka, ibirimo SiO2 biriyongera, kandi ubuso bwihariye nubunini bwa pore nabyo biriyongera.Kubwibyo, ingaruka zitwara isi itunganijwe neza iruta iy'isi isanzwe ya diatomaceous.

Ubutaka bwa Diatomaceous busanzwe bukorwa mubisigazwa bya silikate nyuma y'urupfu rwa algae ingirabuzimafatizo imwe, bakunze kwita diatom, kandi ishingiro ryayo ni amorphous SiO2 y'amazi.Diatom irashobora kubaho mumazi meza namazi yumunyu, hamwe nubwoko bwinshi.Mubisanzwe barashobora kugabanywa muri diatom ya "central order" hamwe na diatom "itondekanya amababa", kandi buri cyiciro gifite "genera" nyinshi zigoye cyane.

Ibintu nyamukuru bigize isi isanzwe ya diatomaceous ni SiO2, hamwe nubwiza bwo hejuru bufite ibara ryera kandi ibirimo SiO2 akenshi birenga 70%.Diatom imwe imwe idafite ibara kandi ibonerana, kandi ibara ryisi ya diatomaceous biterwa nubutare bwibumba nibintu kama.Ibigize isi ya diatomaceous biva mumasoko atandukanye biratandukanye.

Isi ya Diatomaceous, izwi kandi ku izina rya diatom, ni ikigega cya diatom cyabitswe nyuma y’urupfu rw’ikimera kimwe kandi igihe cyo kubitsa kimaze imyaka 10000 kugeza 20000.Diatom yari kimwe mu binyabuzima bya mbere byagaragaye ku isi, bituye mu nyanja cyangwa mu kiyaga.

Ubu bwoko bwisi ya diatomaceous buterwa no gushira ibisigazwa byibinyabuzima byo mu mazi bifite ingirabuzimafatizo imwe.Imikorere idasanzwe yiyi diatom nuko ishobora kwinjiza silikoni yubusa mumazi kugirango igire amagufwa yayo.Iyo ubuzima bwayo burangiye, burabika kandi bugakora ubutaka bwa diatomaceous mubihe bimwe na bimwe bya geologiya.Ifite ibintu byihariye bidasanzwe, nk'ubukonje, kwibanda cyane, ubuso bunini bwihariye, ugereranije no kudahuza, hamwe n’imiti ihamye.Nyuma yo guhindura ingano yubunini bwo gukwirakwiza nubuso bwubutaka bwumwimerere binyuze muri procinzira yo gutondeka nko guhonyora, gutondeka, kubara, gutondeka ikirere, no kuvanaho umwanda, birashobora kuba byiza mubisabwa mu nganda zitandukanye nko gutwikira no kongeramo amarangi.
