what is the world strongest substances full explanation
Answers
Answer:
#10 SPIDERS’ SILK
Darwin bark spiders’ silk is considered the toughest biological substance. It is 10 times stronger than Kevlar. A strand long enough to circle the Earth would weigh less than 500 grams!
#9 SILICON CARBIDE
This material forms the basis of armor used in battle tanks. Highly effective – not one British Challenger tank was destroyed in Operation Desert Storm.
#8 NANOSPHERES / NANO-KEVLAR
Self-assembling nanospheres are the stiffest organized material ever created. It is said that they could lead to the development of printable body armor.
#7 DIAMOND
The hardest material on Earth. It has unrivaled resistance to scratching.
#6 WURTZITE BORON NITRIDE
This material is created during volcanic eruptions and is theoretically 18% harder than diamond. However, large enough quantities don’t exist to test this theory.
#5 LONSDALEITE
Formed when meteorites containing graphite hit Earth. Simulations show it to be 58% harder than diamond, but, again, it’s too rare to test.
#4 DYNEEMA
High-performance polythene marketed as the strongest fiber in the world. Lighter than water, it can stop bullets and is 15 times stronger than steel.
#3 METALLIC GLASS
Palladium microalloy glass has the best combination of toughness and strength. It’s thought to be the most durable material on the planet.
#2 BUCKYPAPER
Nanotechnology material made from tube-shaped carbon molecules 50,000 times thinner than human hair. It’s 500 times stronger than steel and 10 times lighter.
#1 GRAPHENE
One-atom-thick sheets of carbon are 200 times stronger than steel. It would take an elephant balancing on a pencil to break a sheet as thin as Saran wrap.
Answer:
Carbon nitrite
Explanation:
It is isostructural with Si3N4 and was predicted to be harder than diamond. ... Carbon nitrite is only stable at a pressure that is higher than that of the graphite-to-diamond transformation.
