Here are the key facts extracted from the text:
1. Titanium is in the fourth group of the periodic table of elements.
2. Titanium is found in nature in minerals such as titanite or rutile.
3. In its pure form, titanium is a silver-gray, light metal.
4. Titanium has the highest strength-to-weight ratio of all elements.
5. Titanium plates can weigh 50% less than steel plates but have the same strength.
6. Titanium has the property of pyrophoricity, meaning small particles can ignite in air.
7. Titanium powder burns well in air, forming bright sparks.
8. Titanium is often used in pyrotechnics to create bright pyrotechnic fountains.
9. Titanium is often cut with a special guillotine to prevent sparks and risk of fire.
10. Titanium has high viscosity, making it difficult to cut with a grinder.
11. Titanium is resistant to being hit by a bullet, with a higher viscosity and strength than steel.
12. Titanium has a high resistance to corrosion and oxidizes in air only at temperatures above 1000 degrees.
13. Titanium dioxide is formed when titanium oxidizes.
14. The Soviet Union was the first to use titanium in aircraft manufacturing and submarine construction.
15. Titanium is used in aircraft industry, including impellers, turbines, and engine parts.
16. Titanium is used in medical implants due to its excellent biocompatibility and low toxicity.
17. Titanium dioxide is an excellent inert pigment used in toothpastes, tablets, and cleaning agents.
18. Titanium nitride is one of the hardest substances and is used to coat metal drills.
19. Titanium nitride is used to coat church domes, spoons, and spinners due to its gold-like appearance and durability.
20. Titanium has a high price due to the difficult and expensive method of obtaining it.
