No. Diamond is the hardest mineral. It measures 10 on the Mohs scale: Corundum measures 9, which is less hard than diamond, as below.
Diamond is harder than iron. Diamond is the hardest known natural mineral and can scratch iron.
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
Boron nitride is a synthetic material that is harder than diamond. It exhibits similar properties to diamond but has a higher hardness level.
The hardness of silicon is around 7 on the Mohs scale, which means it is harder than most minerals but softer than minerals like diamond or corundum. Silicon is commonly used in electronics and solar panels due to its properties such as hardness and conductivity.
Diamond is much harder than copper. On the Mohs hardness scale (higher numbers are harder), diamond is a 10 and copper is somewhere between 3 and 4.
If you mean isn't harder than quartz but harder than apatite ( you spelled it wrong), that would be Orthoclase Feldspar. Else the minerals that are harder than both apatite and quartz are topaz, corundum, and diamond (diamond being the hardest, well the hardest non synthetic mineral).
No Feldspar is rated 6 on the Mohs Scale and diamond is rated 10. The mineral which is rated 9 on the Mohs is Corundum but there are other minerals which are harder that that but less harder than diamond.
includes: Quartz, Topaz, Corundum, and Diamond. Look up MOHS Hardness Scale. It shows minerals (1-10) softest to hardest. :)
Diamond, with a hardness rating of 10 on the Mohs scale, is harder than corundum (ruby and sapphire), which has a hardness rating of 9. However, diamond has perfect cleavage while corundum has no cleavage. So an answer to the original question would depend on the meaning of "strong."
Topaz (8), corundum (9), and diamond (10).
No. Diamond is harder than emerald.
Diamond is harder than plastic.
Diamond is harder than onyx.
nothings harder than a diamond
Diamond is harder than any metal.
Yes, diamond is harder than granite. Diamond is the hardest mineral known. And it is several times harder than granite.
A diamond is by far the hardest material on earth. On the Mohs scale of hardness -- ranked 1 to 10 -- diamonds are 10, which is more than 10 times harder than the closest at 9, a ruby - corundum (aluminium oxide). The stone, marble, is usually in the 6-7 range. A toy marble can be made from glass, clay, steel, or agate, none of which is as hard as a diamond.
