| 0:00.0 | titanium is the ninth most abundant element in the earth's crust. |
| 0:03.7 | However, titanium is not even remotely close to being the ninth most common element |
| 0:08.1 | in industrial commercial use. |
| 0:09.7 | In fact, despite being so abundant, we didn't even know titanium existed until the late 18th century, |
| 0:15.6 | and we couldn't figure out how to actually practically use it until the 1960s. |
| 0:20.0 | It's a remarkable metal with amazing properties that still is incredibly hard to use. |
| 0:25.0 | Learn more about titanium, the amazing yet difficult metal on this episode of Everything Everywhere Daily. everything everywhere daily. titanium is the 22nd element on the periodic table. It's a silvery metal that looks very similar to steel in its pure elemental state. |
| 0:54.0 | It has a very good strength to weight ratio and it's highly resistant to corrosion. |
| 0:58.0 | It's a relatively poor electrical conductor compared to other metals, |
| 1:02.0 | and it doesn't expand or contract much when temperature changes. |
| 1:05.2 | It is also non-toxic and is considered to be biocompatible, which as we'll see in a bit has many useful properties. |
| 1:11.8 | It is the ninth most abundant element in the earth's crust and the fourth most abundant metal. |
| 1:17.0 | The short story about titanium is that it's a metal with really attractive properties and it's very abundant. You would think that such an |
| 1:24.4 | attractive metal would have been used throughout history. However, you'd be wrong. |
| 1:28.1 | No one had a clue that titanium even existed for most of human history. |
| 1:34.4 | The reason why titanium remained hidden had to do with its chemical proclivity to bond with |
| 1:38.6 | pretty much anything. |
| 1:40.8 | This is almost the opposite of how gold reacts, which is why gold is almost always found in its natural metallic state. |
| 1:47.0 | If you remember back to my episode on aluminum, it's the opposite of gold, and it's very similar to titanium, in that pure metallic aluminum almost never exists in nature. |
| 1:56.0 | The difference between aluminum and titanium is that whereas there were very few examples of pure aluminum, |
| 2:02.0 | there are no known examples of pure titanium. |
| 2:05.0 | Humans in history were aware of and did use compounds that contain titanium, |
