Question

Fe3o4 is an example of which of amterial

Answer 1

iron(|| ,|||) oxide and in nature it occurs as a mineral magnetite

Answer 2

Fe3O4 is an example of metal oxides.

Fe3O4:

• Fe3O4 is the chemical formula for iron(II, III) oxide.
• The mineral magnetite is how it appears in nature.
• It is one of several types of iron oxides, along with rare iron(II) oxide and iron(III) oxide, both of which naturally exist as the mineral hematite.
• Iron oxide Fe3O4 nanoparticles are employed in a variety of sectors, including wastewater treatment, ferrofluids, magnetic coatings, biosensors, etc.

Metal oxides:

• A metal cation and an oxide anion are both present in crystalline solids known as metal oxides.
• Normally, they interact with water to create bases or with acids to create salts.
• The use of metal oxides in sensor and biosensor applications is widely established.
• In actuality, a crucial element for successful interaction with target molecules is the surface of metal oxides.
