Q:What refractories are resistant to fluorine gas?

It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica?brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
