What else can I help you with?
Which mineral has a hardness of 2.5 3 and makes a good electrical insulator?
Biotite mica
Is biotite magnetic?
no,biotite is not attracted to magetic forces (its not attracted to magnet)
Is muscotive mica more mafic and less dense than biotite mica?
Muscovite mica is generally less mafic and less dense than biotite mica. Muscovite is a potassium aluminum silicate, while biotite contains iron and magnesium, giving it a more mafic composition. As a result, biotite is denser than muscovite, which typically has a lower specific gravity due to its higher aluminum and silicon content.
Can biotite scratch glass?
No, biotite cannot scratch glass. Biotite has a hardness of about 2.5 to 3 on the Mohs scale, while glass typically has a hardness of around 5.5. This means that biotite is significantly softer than glass and will not be able to scratch it.
Is Muscovite mica hardness?
Muscovite mica has a hardness of around 2-2.5 on the Mohs scale.
How are the minerals biotite mica and the Muscovite mica different?
Biotite mica contains iron and/or magnesium, but muscovite mica does not.
What element is present in biotite mica that is not present in muscovite mica?
Iron is present in biotite mica but not in muscovite mica.
Which mineral has a hardness of 2.5 3 and makes a good electrical insulator?
Biotite mica
What mineral is known as black mica?
Black mica is also known as biotite. It is a common phyllosilicate mineral that is part of the mica group. Biotite is typically black or dark brown in color and is composed of potassium, iron, magnesium, aluminum, silicon, and hydrogen.
Where is biotite mico mined?
Biotite mica is mined in various countries including India, South Africa, Brazil, and the United States. India is one of the leading producers of biotite mica in the world.
Is biotite a mineral or non-mineral?
Biotite is definitely a mineral. It's in the same family as muscovite, another mineral in the mica family.
Is biotite magnetic?
no,biotite is not attracted to magetic forces (its not attracted to magnet)
What is a biotite?
A biotite is a variety of dark brown mica, a mixed aluinosilicate and fluoride of potassium, magnesium and iron.
Why is biotite not able to be seen?
Biotite is a form of mica, and can be seen without difficulty in the right kind of rocks.
What group is mica in?
Mica is a group of sheet silicate minerals (e.x of micas : Biotite, muscovite)
What is the difference between mica and quartz?
Biotite mica contains iron and/or magnesium, but muscovite mica does not.
Is Muscovite mica hardness?
Muscovite mica has a hardness of around 2-2.5 on the Mohs scale.
