A wurtzite is a dark brown mineral, a form of zinc sulphide, often containing iron and cadmium sulphides.
What else can I help you with?
Is there a stronger mineral than diamond?
Yes, there are a few minerals that are stronger than diamond. Wurtzite boron nitride and lonsdaleite are both harder than diamond on the Mohs scale of mineral hardness. However, these minerals are very rare and not commonly found in nature.
What is the refractive index of nitrobenzene?
Option A: see RefractiveIndex.INFOOption B: If you have access, see the articlehttp://dx.doi.org/10.1016/S0022-3697(96)00219-3which has both theoretical and experimental data. It depends on frequency, of course, and also whether you're talking about zincblende or wurtzite GaN. For wurtzite, it also depends on direction.If I'm reading Figure 4 correctly, the zero-frequency index of refraction is supposed to vary between about 2.25 and 2.4, depending on structure and direction.The article is from 1996, so presumably there are newer, better papers since then.
How many atoms are there in ZnO?
32
What are some characteristics of a diamond?
Precious stones and gems are usually charachterized by Clarity, Hardness and size. Wurtzite boron nitride is the hardest gem recently beating Diamond by 18% although Diamond is rated 10 on Moh's Scale the clarity and carat wieght determines price
Is there any man made metal out there as strong or stronger than diamond?
Diamond was considered the hardest substance; outside of the Earth you can count the iron on a neutron star which is 100 times stronger than normal earth iron but it couldn't retain its strength or mass on earth. Also, the crust of the sun is muchstronger than diamonds, steel or titanium. There is also a new material scientists created by mixing molten tin and barium titanate, this new material is considered harder and stiffer than a diamond.
What is a wurtzite?
A wurtzite is a dark brown mineral, a form of zinc sulphide, often containing iron and cadmium sulphides.
Is wurtzite harder than diamond?
No. Diamond is the hardest natural mineral, measuring 10 on the Mohs scale of hardness. Wurtzite measures 3.5-4 on the same scale. Diamond is formed from carbon -- C; Wurtzite is formed from zinc iron sulfide -- ((Zn,Fe)S).
What has the author J M Stuve written?
J. M. Stuve has written: 'Low-temperature heat capacities of sphalerite and wurtzite' -- subject(s): Sphalerite, Wurtzite 'Thermodynamic properties of NiBr and NiSo from 10 to 1,200 K' -- subject(s): Nickel, Thermal properties
What is the hardness known mineral?
Diamond used to be considered the hardest mineral, but apparently now it is Wurtzite Boron Nitride.
Which is hardest material on the Earth?
For many years, scientists identified diamond as the hardest substance on earth. However, the girl's best friend has been surpassed by Wurtzite Boron Nitride (#1) and Lonsdaleite (#2). Lonsdaleite is not a natural earth substance, since it is composed of what is left after meteoroids strike earth. Wurtzite Boron Nitride has a chemical structure similar to diamond, but is strengthened by some additional chemical bonds forged within volcanos.
What is the chemical name for zinc blend?
zinc sulfide wurtzite sphalerite matraite
What is stronger than a diamond?
Wurtzite Boron Nitride (w-BN) is a bit harder and stronger than diamonds. However, lonsdaleite (also called Hexagonal Diamond) is 58% harder than a diamond!
Which is the hardest substace available on earth?
Diamond has always been considered the hardest natural substance in the world. However, wurtzite boron nitride and mineral lonsdaleite have recently been discoverd and are much harder than diamond.
What is the hardest natural material found in the entire universe?
The hardest material known to man is currently called lonsdaleite (a carbon form), which is approx. 58 % harder than a diamond and then there is wurtzite boron nitride which is about 18% harder than diamond. Both occur in nature just like diamonds.
Is there a stronger mineral than diamond?
Yes, there are a few minerals that are stronger than diamond. Wurtzite boron nitride and lonsdaleite are both harder than diamond on the Mohs scale of mineral hardness. However, these minerals are very rare and not commonly found in nature.

What is the hardest mineral?
Diamond is the hardest mineral, scoring a 10 on the Mohs scale of mineral hardness. Its hardness is due to the strong covalent bonds between its carbon atoms, making it resistant to scratching or breaking.
