Silica silica ee loo yaqaan 'Metro RPC' oo daboolaya saxanka ima si silsila ah oo sifooti ah ayaa si gaar ah loogu dari karaa daboolida RPC ee loo isticmaalo marinnada dhulka hoostiisa. Budada microsilica waa nooc ka mid ah buufiye dhexdhexaad ah oo dhexdhexaad ah oo leh guryo jir ahaaneed iyo kiimiko ah, kuma jiraan biyo crystallone, kama qeybqaato falcelinta daaweynta, mana saameynayso hababka falcelinta. Qaabka Silica ee loo yaqaan 'Silica' ee loo qaybinayo tirada walxaha loo yaqaan 'Tree rC' waa macquul macquul ah, cufan, si weyn, waxay si weyn u hagaajin kartaa khasab, xoog, awood u leh xoogga, awooda loo adkeysto ee maaddada la-dagaallanka ah, ayaa lagu kordhin karaa 0.5- 2.5 jeer. Marka qaddarka 5-10%, xoogga la taaban karo ee la taaban karo waxaa kor loogu qaadi karaa 10-30%, awoodda dabacsanaanta in ka badan 10%, qasabka ah caabbinta caadadu waxay kordhaysay in ka badan 4 jeer, micro- La taaban karo budada silica ee loo yaqaan 'Isuduwinta' Silica Powder 'ee la taaban karo ee la taaban karo ee kordhay 0.5-2.5 jeer, caabbinta cafiska ayaa kordhay 3-16 jeer, waa xarkaha biyaha, biyo-xireennada si loo dayactiro iyo ilaalinta dusha sare ee qalabka ugu fiican. Sababta oo ah cabirka walxaha gaaska ah iyo qeybinta macquulka ah ee budada micro-silicon, waxay si wax ku ool ah u yareyn kartaa ifafaalaha roobka iyo xaraashka, si fudud wax u qabashada xayeysiinta xayeysiinta ah, oo sahlan.
