He mea kupaianaha ka pauka lepo diatomaceous i loaʻa mai nā koena fossil o nā diatoms, ʻo ia hoʻi nā limu cell hoʻokahi. Ua ulu maikaʻi kēia mau diatoms i loko o nā kino wai e like me nā moana, nā loko, a me nā muliwai miliona mau makahiki i hala. I ko lākou make ʻana, ua hōʻiliʻili ʻia ko lākou mau paia cell waiwai silica ma lalo, e hana mālie ana i nā waihona sedimentary ʻo ia ke kumu o ka lepo diatomaceous.

ʻO kekahi o nā hiʻohiʻona ʻokoʻa loa o ka pauka lepo diatomaceous ʻo ia kona ʻano porous kiʻekiʻe. Ma ke ʻano microscopic, hōʻike ia i kahi pūnaewele paʻakikī o nā pores liʻiliʻi a pili pū kekahi. ʻOkoʻa ka nui o kēia mau pores, maʻamau mai kekahi mau nanometers a i kekahi mau micrometers. Hāʻawi kēia porosity i ka pauka i kahi ʻāpana ʻili nui loa no kēlā me kēia anakahi nui, he mea nui ia no kāna mau noi he nui. No ka laʻana, i nā kaʻina hana kānana, hiki i nā pores ke hoʻopaʻa i nā ʻāpana o nā nui like ʻole, e hana ana ma ke ʻano he kānana kūlohelohe.

Loaʻa nā noi o ka pauka honua diatomaceous i nā mea hoʻonani a me ka ʻoihana mālama pilikino. Hoʻohana ʻia ia i nā ʻūlū maka a me nā huahana exfoliating ma muli o kona mau waiwai abrasive palupalu. Hiki iā ia ke kōkua i ka wehe ʻana i nā ʻili make, e waiho ana i ka ʻili me ka laumania a me ka hoʻoulu hou ʻia. I loko o kekahi mau ʻano toothpaste, ua hoʻokomo ʻia ia ma ke ʻano he abrasive palupalu e kōkua i ka hoʻomaʻemaʻe ʻana i nā niho a wehe i ka plaque me ka ʻole o ka hōʻino nui ʻana i ka enamel niho.

I ka ʻoihana, hoʻohana ʻia ka pauka lepo diatomaceous ma ke ʻano he mea hoʻopiha i nā huahana e like me nā plastics, rubber, a me nā pena. I loko o nā plastics, hiki iā ia ke hoʻonui i nā waiwai mechanical o ka matrix plastic, e like me ka hoʻonui ʻana i kona ikaika a me ka paʻakikī. I loko o ka rubber, hiki iā ia ke hoʻomaikaʻi i ke kūpaʻa a me ke kūpaʻa o nā huahana rubber. I loko o nā pena, hana ia ma ke ʻano he mea hana moena, e hōʻemi ana i ka ʻōlinolino o ka ʻili pena a hāʻawi i kahi ʻano matte. Hoʻohana ʻia hoʻi ia i ka hana ʻana o ka dynamite ma ke ʻano he ʻāpana hoʻopaʻa, e kōkua ana i ka kaohi ʻana i ka hopena pahū.
