Parizvino, pane nzira mbiri dzekugadzira silica. Imwe inzira yekunaya kwemvura, uye nzira yayo yese ndeye:
Chekutanga, jecha requartz rinoitwa nesoda ash pakupisa kwakanyanya uchishandisa mafuta emafuta kana gasi kugadzira girazi remvura mumaindasitiri. Girazi remvura yeindasitiri rinobva rasanganiswa nemvura kuti riite dilute solution yeimwe concentration. Mune mamwe mamiriro ezvinhu, imwe asidhi inowedzerwa kune precipitate silicon dioxide. Mushure mekuchenesa, kusefa, kuomesa, uye kupwanya, chigadzirwa silica inowanikwa. Iyo nzira yekunaya inogona kukamurwazve kuita dzakawanda dzakasiyana nzira senge acid nzira, sol nzira, carbonization nzira, nezvimwe.
MuChina, nzira yeasidhi inonyanya kugamuchirwa. Iyo asidhi nzira inosanganisira kuita soluble silicates ne sulfuric acid (kana mamwe maasidhi). Kana mhinduro yemhinduro yasvika imwe pH kukosha, iyo acid yekuwedzera reaction inomiswa, ichiteverwa nekuchembera. Zvadaro, musanganiswa unosefa uye unoshambidzwa kakawanda nemvura kuti ubvise Na2SO4. Mushure mezvo, inotumirwa kuomeswa nekukuya kuti iwane chigadzirwa.
