Diatomiteyog ib hom pob zeb siliceous, feem ntau tawg nyob rau hauv Tuam Tshoj, Tebchaws Asmeskas, Denmark, Fabkis, Romania thiab lwm lub tebchaws. Nws yog ib yam ntawm cov pob zeb biogenic siliceous accumulation, uas yog tsim los ntawm cov seem ntawm ancient diatoms. Nws cov tshuaj muaj pes tsawg leeg feem ntau yog SiO2, uas tuaj yeem sawv cev los ntawm SiO2·nH2O, thiab cov ntxhia muaj pes tsawg leeg yog opal thiab nws cov variants.

Tuam Tshoj muaj 320 lab tons ntawmdiatomaceous ntiaj tebreserves thiab ntau tshaj 2 billion tons ntawm yav tom ntej reserves, uas yog mas concentrated nyob rau hauv East Tuam Tshoj thiab Northeast Tuam Tshoj. Ntawm lawv, qhov ntau yog qhov loj, thiab Jilin muaj ntau qhov tshwj xeeb (54.8%, ntawm cov pov thawj reserves ntawm Linjiang City, Jilin Province account rau Asia.), Zhejiang, Yunnan, Shandong, Sichuan thiab lwm lub xeev, txawm hais tias kis tau dav, tab sis cov av zoo tsuas yog concentrated nyob rau hauv Changbai Roob thaj tsam ntawm 4 lwm cov av, thiab feem ntau ntawm cov pob zeb hauv av. Vim yog cov ntsiab lus impurity siab, lawv tsis tuaj yeem ua tiav ncaj qha thiab siv tau. Cov tshuaj muaj pes tsawg leeg ntawm diatomite feem ntau yog SiO2, muaj me me ntawm Al2O3, Fe2O3, CaO, MgO, thiab lwm yam. thiab cov organic teeb meem. Muaj me me ntawm Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5 thiab cov organic teeb meem. SiO2 feem ntau suav nrog ntau dua 80%, mus txog 94%. Cov ntsiab lus hlau oxide ntawm lub ntiaj teb zoo diatomaceous feem ntau yog 1 ~ 1.5%, thiab cov ntsiab lus alumina yog 3 ~ 6%. Cov ntxhia muaj pes tsawg leeg ntawm diatomite feem ntau yog opal thiab nws cov variants, ua raws li av nplaum minerals-hydromica, kaolinite thiab ntxhia detritus. Mineral khib nyiab muaj xws li quartz, feldspar, biotite thiab organic teeb meem. Cov ntsiab lus ntawm cov organic sib txawv ntawm cov kab mob mus rau ntau tshaj 30%. Cov xim ntawm lub ntiaj teb diatomaceous yog dawb, tawm-dawb, grey thiab lub teeb grey-xim av, thiab lwm yam. Nws muaj cov yam ntxwv ntawm fineness, looseness, lub teeb yuag, porosity, dej nqus thiab muaj zog permeability. Feem ntau ntawm silica ntawm diatomite yog non-crystalline, thiab cov ntsiab lus ntawm soluble silicic acid nyob rau hauv alkali yog 50 ~ 80%. Amorphous SiO2 ua siv lead ua thaum rhuab mus rau 800 ~ 1000 ° C, thiab soluble silicic acid hauv alkali tuaj yeem txo mus rau 20 ~ 30%.

Diatomaceous ntiaj tebyog non-toxic, yooj yim rau kev sib cais ntawm cov zaub mov, thiab tuaj yeem siv dua tom qab sib cais. Nws tau raug lees paub los ntawm ntau tus kws tshaj lij tshuaj tua kab ua tshuaj tua kab. Qhov laj thawj yog vim li cas lub ntiaj teb diatomaceous tuaj yeem tiv thaiv kab tsuag yog tias thaum cov kab nkag mus rau hauv cov khoom noj sib xyaw nrog diatomaceous lub ntiaj teb, lub ntiaj teb diatomaceous yuav ua raws li kab kab hauv lub cev, rhuav tshem cov kab waxy txheej ntawm kab epidermis thiab lwm yam dej tsis sib haum, thiab ua rau kab kab. Kev poob dej ua rau tuag taus. Diatomaceous ntiaj teb thiab nws cov extracts kuj tseem siv tau los ua tshuaj tua kab thiab tshuaj tua kab mob hauv cov liaj teb orchards. Diatomaceous ntiaj teb hais tuaj yeem muab faib rau hauv huab cua lossis faus rau hauv av kom nqus tau thiab tua qee cov kab tsuag. Diatomaceous lub ntiaj teb tuaj yeem siv los ua tus neeg nqa khoom zoo heev thiab txheej txheej rau cov tshuaj chiv. Cov micropores ntawm qhov chaw ntawm lub ntiaj teb diatomaceous tuaj yeem sib npaug nqus thiab qhwv cov tshuaj chiv kom tsis txhob qhib lub sijhawm ntev thiab kev nqus dej thiab agglomeration. Nws muaj 60-80% diatoms. Tus tshiab environmentally friendly biochemical fertilizer nrog av thiab me me ntawm microbial flora tuaj yeem txhim kho lub cev tsis muaj zog ntawm cov nroj tsuag nws tus kheej, txhawb kev loj hlob ntawm cov nroj tsuag, thiab txhim kho cov av nws tus kheej kom ua tiav lub hom phiaj ntawm kev txo qis cov chiv zoo tib yam thiab tshuaj tua kab los ntawm 30-60% thaum cog kev loj hlob.
