Ekirala ye ggaasi-enkola ya phase, enkola y’okuteeka omukka mu mubiri (CAV), era emanyiddwa nga pyrolysis method, enkola enkalu oba enkola y’okwokya. Ebintu byayo ebisookerwako okutwalira awamu biba silikoni tetrachloride, okisigyeni (oba empewo) ne haidrojeni, ebikola ku bbugumu erya waggulu.
The reaction equation is: SiCl4+2H2+O2 - >SIO2+4HCl. Empewo ne haidrojeni bikolebwako puleesa, okwawula, okunyogoza n’okuggwaamu amazzi, okukala kwa silika, okuggyawo enfuufu n’okusengejja nga tebinnasindikibwa mu kyokero kya synthetic hydrolysis. Oluvannyuma lw’ekintu ekibisi ekya silikoni tetrachloride okusindikibwa mu kisenge ky’okufuumuula okusobola okufumbisa, kibuguma ne kifuumuulwa mu kiwujjo, n’oluvannyuma ne kisindikibwa mu kikoomi eky’okusengejja amazzi (synthetic hydrolysis furnace) n’empewo enkalu n’esengekebwa ng’ekitwala. Silicon tetrachloride efuumuulwa ku bbugumu erya waggulu (ebbugumu ly’omuliro 1000-1800℃) n’oluvannyuma n’efuna ggaasi-okusengejja amazzi mu phase n’omuwendo ogugere ogwa haidrojeni ne okisigyeni (oba empewo) ku diguli nga 1800 . Mu kifo kino, obutundutundu bwa silika bwa ggaasi ne phase obukolebwa buba bulungi nnyo era bukola aerosols ne gaasi, ebizibu okukwata.
N’olwekyo, zisooka kugatta mu butundutundu obunene mu kiyungo, oluvannyuma ne zikung’aanyizibwa ekyuma eky’okwawula cyclone, ne zisindikibwa mu kyokero eky’okuggyamu amazzi. Gaasi-Fase silika enaazibwa ne nayitrojeni-efuuwa empewo okutuusa omuwendo gwa pH lwe guli 4 okutuuka ku 6, nga kino kye kintu ekiwedde .
