- It is a very hard naturally formed material that is 58 percent harder then diamond. btw my IQ is 140 :D
- It is a derivative substance of graphite on meteorites when they hit the earth. The pressure and heat on the graphite turn it into lonsdaleite, when entering the earth's atmosphere. And my IQ is above 140 :P.
What else can I help you with?
Which is the second natural hardest substance in the world?
The second hardest substance in the world is mineral lonsdaleite, or hexagonal diamond. It's made up from the same materials as diamonds, but it has a slightly different structor. Mineral lonsdaleite is extremely rare in nature.
What is the 2 hardest mineral besides dimionds?
The two hardest minerals besides diamonds are moissanite and lonsdaleite. Both of these minerals have a hardness level that is close to that of diamonds on the Mohs scale of mineral hardness.

Which type of power station uses chemical energy to generate electricity coal fired or nuclear?
A coal-fired power station uses chemical energy from burning coal to generate electricity. A nuclear power station uses nuclear reactions to generate electricity.
Which type of transformation uses a scale factor?
A similarity transformation uses a scale factor to enlarge or reduce the size of a figure while preserving its shape. It includes transformations such as dilation and similarity.
What is the density of lonsdaleite?
The density of lonsdaleite, which is a type of carbon allotrope, is approximately 3.2 g/cm^3. Lonsdaleite is a hexagonal diamond structure with carbon atoms arranged in a different configuration, giving it higher hardness than regular diamond.
What are the geometric shapes of the carbon allotropes?
Diamond,Graphite,Lonsdaleite, Buckminsterfullerene
Where can you buy the mineral lonsdaleite online?
Nowhere, I also searched the whole internet (3 google pages) but I didnt find it. However, I own a possible chunk of the material (113 grams). I searched for all of the features lonsdaleite contains and it seems that it all matches. bye
What is the one substance stronger than a dimond?
Lonsdaleite has been recently discovered by scientists,I mean who else has the time?
When is lonsdaleite softer than a diamond?
Lonsdaleite is formed within meteorites and found when the meteorites land on earth. This is another alltrope of carbon, but with a different -- Hexagonal dihexagonal dipyramidal -- crystal structure. It is always softer than a diamond, because a diamond's crystal structure maximizes the carbon's valance -- four -- into its rigid tetrahedral network of covalent bonds on eight sides.
What natural mineral is harder than a diamond?
There is noneAnswer:There are two naturally occurring materials harder than normal diamonds:The first, wurtzite boron nitride has a similar structure to diamond, but is made up of different atoms. It is formed during volcanic eruptions that produce very high temperatures and pressures. Wurtzide boron nitride can withstand 18% more stress than diamond,The second, lonsdaleite, or hexagonal diamond is made from carbon atoms just like diamond, but they are arranged in a different shape. Lonsdaleite is sometimes formed when meteorites containing graphite hit Earth. It is estimated that lonsdaleite 58% more stress than diamond..
Is lonsdaleite the hardest material?
No, the hardest material known is diamond. Edit: Actually, diamond is only the hardest material which occurs naturally in macroscopic crystalline form. While the lonsdaleite found in meteorite craters has a Mohs hardness of about 7-8 (as opposed to diamond's 10), this is due to impurities and imperfections. It has been calculated that a pure lonsdaleite crystal would be 58% harder than diamond. Similarly, a crystal of wurtzite boron nitride would also be harder than diamond, although a method of producing such crystals is still to be found.
Which is the second natural hardest substance in the world?
The second hardest substance in the world is mineral lonsdaleite, or hexagonal diamond. It's made up from the same materials as diamonds, but it has a slightly different structor. Mineral lonsdaleite is extremely rare in nature.
What are the top ten hardest things on earth on a scale?
Diamond Titanium Tungsten Steel Chromium Zirconia Lonsdaleite Silicon carbide Boron nitride Cubic zirconia
Can lonsdaleite be used for jewellry?
It could be used for jewelry, but since it is formed only when meteorites containing graphite hit Earth, it will be a very expensive material. Pray that it could be syntactically made in laboratories.
What kind of molecule is the element carbon?
Carbon has a number of allotropes, (forms) Graphite - sheets of fused hexagons Diamond - giant molecule Lonsdaleite another crystalline form similar to diamond fullerenes- finite"spheres" with 5 and six membered rings of carbon and tubes They are all covalently bonded- most have delocalised electrons - exceptions are diamond and lonsdaleite Wikipedia article is not a good article but it does have some informative pictures
What are some of the hardest natural materials known to man?
Lonsdaleite, diamond, and wurtzide boron nitrid. http://www.newscientist.com/article/dn16610-diamond-no-longer-natures-hardest-material.html
