Question

give one example of acidic flux basic flux

Answer 1

Acidic flux:

Acidic flux  are those flux which comes from substances like Lewis acid such as SiO2, H3PO4, HCl etc.

Acidic flux is used in metal welding or extractive metallurgy or Smelting.

Silica (SiO2) is used to remove basic earthly impurities (gangue) such as lime (CaO) or MgO.

 

Basic flux:

It is similar to Acidic flux but only difference is that we take basic substances like CaO for welding process or extractive metallurgy or Smelting. 

Basic fluxes like lime (CaO), magnesium oxide (MgO) are used to remove acidic gangue such as SiO2.

Answer 2

Hello friend,

● Acidic flux -
- Acidic flux is the substance added to molten metals to bond with basic impurities that can be readily removed.
- For example, silica is used to remove calcium oxide impurities from the ore.
SiO2 + CaO --> CaSiO3

● Basic flux -
- Basic flux is the substance added to molten metals to bond with acidic impurities that can be readily removed.
- For example, limestone is used to remove silica impurities from the ore.
CaCO3 + SiO2 --> CaSiO3 + CO2

Thanks for asking..
