Izitini Eziphikisayo ZaseSilica

Incazelo emfushane:

Izinga eliphakeme le-silica isitini lenziwe ngezinto eziluhlaza ze-silicon, okuqukethwe kwe-SiO2 kungaphezulu kwama-91%. Futhi okuqukethwe kwe-Al2O3 kungaphansi kwe-1,0%.

Ukusebenza
Zisetshenziswa kabanzi esithandweni sokuqhuma esishisayo, kuhhavini we-coke, kanye nesithando sengilazi. Imikhiqizo ingenziwa ngokuya ngesidingo samakhasimende.

Inzuzo
1) I-Silicon oxide ingaphezulu kwama-91%.
2) Ukumelana okuhle kokuguguleka kwe-acid.
3) Phuzu lokuthambisa eliphakeme lokushisa.
4) Akukho ukuncipha ekushiseni okuphindaphindiwe.
5) Ubushushu bokuphinda ubuye phansi komthwalo bungaphezu kwe-1650º C
