Which substance is the hardest?
Diamond is the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa. Diamond demonstrates both high thermal conductivity and electrically insulating properties, and much attention has been put into finding practical applications of this material.
What are the top 5 hardest substances on earth?
Below are the 10 strongest materials known to man:

- #7 Diamond.
- #6 Wurtzite Boron Nitride.
- #5 Lonsdaleite.
- #4 Dyneema.
- #3 Metallic Glass.
- #2 Buckypaper.
- #1 Graphene. One-atom-thick sheets of carbon are 200 times stronger than steel.
What’s the strongest substance on earth?
Diamond is the hardest substance found on earth in so many natural forms, and it is an allotrope of carbon. The hardness of diamond is the highest level of Mohs hardness – grade 10. Its microhardness is 10000kg/mm2, which is 1,000 times higher than quartz and 150 times higher than corundum.
Are nails stronger than teeth?
Not only that, your tooth enamel is the hardest substance in your entire body. Your fingernails, for example, sit much lower on the Mohs scale, ranking in at 2.5.
Which is the hardest part in human body?
We all know that in human body the most hardest part is bone. Femur and Temporal bone of the skull are the strongest bones of the human body. However, tooth enamel is the hardest and most highly mineralized substance in the human body. It’s a tissue and not a bone.
What is the hardest thing in the body?
Enamel is the hardest substance in the body and is almost entirely composed of calcium salts. The hardness of enamel is an important property as the main role of enamel is to protect the softer underlying dentin of the tooth.
What’s the hardest thing in your body?
Tooth enamel is the hardest substance in the body. Enamel is formed on the tooth while the tooth is developing within the gum before it erupts into the mouth. Tooth enamel is one of the four major tissues that make up the tooth in humans and many other animals, including some species of fish.
Which is the hardest tissue of the body?
Enamel, in anatomy, the hardest tissue of the body, covering part or all of the crown of the tooth in mammals. Enamel, when mature, consists predominantly of apatite crystals containing calcium and phosphate. Enamel is not living and contains no nerves.
