Yttrium (version 2)

Yttrium (version 2) - Periodic Table Videos

Introduction

This video by the Periodic Table of Videos discusses the element Yttrium, its discovery, properties, and various applications. The presenters visit the Ytterby Quarry in Sweden, the birthplace of yttrium, and explore its significance in both historical and modern contexts.

Main Points/Arguments

• Discovery and Historical Context:

- Yttrium was first discovered in the Ytterby Quarry, Sweden, from a black mineral initially thought to be coal.

- Over 40 years, scientists refined this material to identify yttria (yttrium oxide), which was eventually isolated as yttrium metal by German scientist Friedrich Wöhler using potassium.

• Properties of Yttrium:

- Yttrium is a lustrous, soft metal from Group 3 of the periodic table.

- It burns readily in an oxygen-rich atmosphere and reacts with water, making it prone to oxidation.

- The metal must be handled under nitrogen to prevent oxidation.

• Applications:

- Semiconductors: Yttrium is used in yttrium barium copper oxides, which are important in various semiconductor applications.

- Laser Technologies: Yttrium is used to create intense light pulses for CDs, LEDs, and other technologies.

- Glass Additives: Yttrium oxisulphide is used to make glass tough, shock-resistant, and temperature-resistant, including bulletproof glass.

- High Temperature Superconductors: Yttrium plays a role in superconducting materials with significant applications in physics and electronics.

• Mining and Abundance:

- The video shows evidence of mining activities at the Ytterby Quarry, highlighting the historical significance of the site.

- Yttrium was found to be present in high abundance in lunar samples brought back by the Apollo astronauts.
