7N grade Synthetic Quartz Sand ahyɛ ase ayɛ mass production!

Bere tenten ni no, me man no semiconductor nnwuma nkɔnsɔnkɔnsɔn no de ne ho ato nneɛma a wɔde ba amannɔne so kɛse ma 7N{1}}Grade High-Purity Quartz Sand, a wɔde di dwuma wɔ semiconductor a wɔyɛ no yiye mu.

Ɔkwan a wɔfa so yɛ nneɛma a ɛkorɔn-ahotew quartz anhwea a efi silicon tetrachloride mu denam nsu so-Phase hydrolysis .

Saa nsusuwii yi da ɔkwan bi a wɔfa so yɛ nneɛma a ɛkorɔn-purity quartz anhwea a efi silicon tetrachloride mu denam nsu-fase hydrolysis so adi. Adeyɛ no fa nsuo-Phase hydrolysis of silicon tetrachloride ne nsuo ho. Aduru no fa ahohoro, solid-liquid separation, drying, calcination, grinding, ne screening mu na ama wɔanya soro-purity quartz powder.
