In the basic Bessemer process for the manufacture of steel, the lining of the converter is made up of ____. The slag formed consists of ____.

Text Solution

Verified by Experts

The correct Answer is:
Lime, `Ca_(3)(PO_(4))_(2)`
In the basic Bessemer process for the manufacture of steel, the lining of converter is made up of lime. The slag formed consists of `Ca_(3)(PO_(4))_(2)`. Phosphorous is oxidised to `P_(4)O_(10)`, which reacts with lime to form slag.
`P_(4) + 5O_(2) rarr P_(4) O_(10)`
`6CaO + P_(4)O_(10) rarr underset(("Thomas slag")) (2Ca_(3)(PO_(4))_(2))`.
