Pob zeb volcanic (feem ntau hu ua pumice lossis porous basalt) yog ib yam khoom siv ua haujlwm thiab zoo rau ib puag ncig, uas yog ib lub pob zeb muaj nqis heev uas tsim los ntawm cov iav volcanic, cov zaub mov, thiab cov npuas tom qab muaj hluav taws tawg. Pob zeb volcanic muaj ntau yam zaub mov thiab cov kab kawm xws li sodium, magnesium, txhuas, silicon, calcium, titanium, manganese, hlau, nickel, cobalt, thiab molybdenum. Nws tsis yog radiative thiab muaj cov nthwv dej magnetic deb-infrared. Tom qab muaj hluav taws tawg tsis muaj kev hlub tshua, tom qab kaum tawm txhiab xyoo, tib neeg tab tom pom nws tus nqi ntau zuj zus. Tam sim no nws tau nthuav nws cov teb thov rau cov teb xws li architecture, dej conservancy, sib tsoo, lim cov ntaub ntawv, barbecue thee, landscaping, soilless cultivation, thiab ornamental products, ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam.

Pob zeb volcanic yog ib hom khoom siv tshiab uas ua haujlwm tau zoo thiab zoo rau ib puag ncig, uas yog pob zeb muaj nqis heev uas muaj qhov ntxeem tau los ntawm cov iav volcanic, cov zaub mov, thiab cov npuas tom qab tawg ntawm cov roob hluav taws. Pob zeb volcanic muaj ntau yam zaub mov thiab cov ntsiab lus xws li sodium, magnesium, txhuas, silicon, calcium, titanium, manganese, hlau, lithium, nickel, cobalt, thiab molybdenum.

Nws cov yam ntxwv yog lub teeb yuag, muaj zog heev, rwb thaiv tsev thermal, nqus suab, tiv taus hluav taws, tiv taus acid thiab alkali, tiv taus corrosion, tsis muaj kuab paug, tsis muaj hluav taws xob, thiab muaj ntau lub qhov me me ntawm qhov chaw, zoo li lub qhov ntawm daim tawv nqaij. Kev tsau hauv roj cav tuaj yeem maj mam nqus cov roj tseem ceeb, thiab tom qab ntawd maj mam tso lawv mus rau ntawm daim tawv nqaij, cia lawv nkag mus rau hauv tib neeg lub cev. Tsis tas li ntawd, nws tau ua ke nrog cov khoom siv roj tseem ceeb thiab cov txheej txheem tshwj xeeb detoxification, Cov pob zeb volcanic tau siv ntau dua hauv kev kho mob thiab kev zoo nkauj hauv xyoo tas los no vim lawv tuaj yeem daws tau ntau yam teeb meem ntawm daim tawv nqaij.
