Tunah hian silica siamna tur kawng pahnih a awm ber a. Pakhat chu ruahtui tlak dan a ni a, a general process route chu:
A hmasa berin, quartz sand chu soda ash nen temperature sang takah fuel oil emaw gas emaw hmangin industrial water glass siam turin an inrem thin. Chumi hnuah chuan industrial water glass chu tui nen an pawlh a, chu chuan dilute solution a siam a, chu chu concentration engemaw chen a ni. Thil awm dan thenkhatah chuan silicon dioxide precipitate turin acid engemaw zat dah a ni. A tihfai, filtration, drying, leh crushing hnuah product silica chu a chhuak thin. Precipitation method hi method bik hrang hrang tam takah then belh theih a ni a, chu chu acid method, SOL method, carbonization method, etc. te hi a ni.
China ramah chuan acid method hi hman a ni ber. Acid method ah hian soluble silicates te chu sulfuric acid (or acid dang) te nen an inrem a. Reaction solution chuan pH value engemaw chen a thlen chuan acid addition reaction chu tihtawp a ni a, chu chu tar a ni. Tichuan, a mixture chu filter-in tuiin a sil nawn leh a, Na2SO4 chu a paih chhuak leh a. Chumi hnuah chuan product hmuh theih nan drying leh grinding atan an thawn thin.
