Seek high-temperature resistant coating or lining material capable of withstanding 1000°C chlorine gas
Thread Content
The company now needs to build a chlorination reactor, with operating conditions of 1000°C at atmospheric pressure. Materials for the lining or coating must be able to resist corrosion by chlorine at 1000°C.
Is it a gas–gas reaction, or a gas–liquid reaction, or a liquid–liquid reaction?
It is a gas-solid reaction, involving chlorine gas, boron oxide, and carbon powder; the reaction temperature is 1000℃
If you find it, could you share it? Thank you

The materials for small-scale devices can be addressed, with no impurities that would affect the purity of the pollution-free products. You can contact by phone or email.
Have you handled similar cases before? Does graphite function as a consumable in the reaction and not participate in it? Could you send the relevant materials to my email 2272283348@qq.com? Thank you!
Graphite oxidizes when in contact with oxygen at 1000 degrees, producing CO2; it does not oxidize if protected by N2. Under high-temperature conditions, graphite reacts slowly with chlorine to produce CCl4; if amorphous carbon is also present, it is the amorphous carbon that reacts preferentially. Since CCl4 is in a gaseous state, it shouldn’t contaminate the product, right?
The product BCl3 is also gaseous, but since carbon is present in our reaction materials, wouldn’t the rate at which the graphite lining is consumed by the reaction be greatly reduced?
