Cufnaanta culus ee loo yaqaan 'Silica' ee loo yaqaan 'Gymnasiums': Noocan microsilica noocan ah waxaa badanaa lagu daraa sibidhka loo isticmaalo dhismaha garoomada si loo kordhiyo xoogga iyo astaamaha kale ee sibidhka.
Freme silica ayaa dheereysan doonta waqtiga bilowga iyo kama dambeysta ee dharka ka dib markii lagu daro sibidh, sidaa darteed kuma haboona in lagu isticmaalo xilliga heerkul hoose;
Sababo la xiriira haynta biyaha adag iyo kala-sooca ee kala-sooca ee silica ku qasbay sibidhka, sibidhka dhismaha ee sibidhka ayaa ka sii dari doona kororka qiyaasta daawada;
Iyada oo loo marayo tijaabooyin iyo wax soo saar dhab ah waxay muujineysaa in silica silic ah oo isku dhafan oo sibidhka ah, arrinta isku-darka ay tahay inay ahaato 3%, taasoo yareyn karta baahida biyaha, kuwaas oo kor u qaadi kara xoogga hore iyo kan dambe;
Falica silica waxay leedahay walxaha wanaagsan iyo halbeeg yar oo miisaan yar, sidaa darteed kaydinta, xasilloonida sheyga iyo cabirka waa in loo qaddariyo marka la isticmaalayo caloosha silica.
Silica silica oo la taaban karo oo xoog badan, cufnaanta culus ee silica ah, oo ah budada microsilica ee firfircoon, silica fme ee sheyga wax lagu buufiyo, siliceus carrada
