What is beta ferrite?
Q: What is beta ferrite?
A: Beta ferrite is a type of ferrite that is paramegnetic instead of ferromagnetic at a temperature of above 771°C.
Q: What does β-Fe refer to?
A: β-Fe refers to an unproven to exist fifth allotrope of iron, only produced once in Uppsala University.
Q: How was β-Fe produced?
A: β-Fe was produced by compressing iron to 35-40 GPa and heating it to 1500°K, then scanning it.
Q: Was the result of β-Fe production ever reproduced?
A: No, the result of β-Fe production was never reproduced.
Q: What is the difference between paramegnetic and ferromagnetic?
A: Paramegnetic means a weak external magnetic field makes a material become magnetized, while ferromagnetic means a material is naturally magnetized.
Q: At what temperature does beta ferrite become paramegnetic?
A: Beta ferrite becomes paramegnetic at a temperature of above 771°C.
Q: What is an allotrope?
A: An allotrope is a different form of an element in the same physical state.
