What is Lead Telluride?
Lead telluride is a solid material that looks like gray crystals. It has a special structure called a cubic shape. This means its tiny parts are arranged in a cube-like pattern.
How is it Made?
Scientists can make lead telluride by melting two elements together: lead and tellurium. When these two elements are heated and mixed, they combine to form this new compound.
What is it Used For?
Lead telluride is very useful in technology. It is known as a semiconductor. This means it can control how electricity flows through it, which is important for electronic devices.
It is also used in infrared detectors. These detectors can "see" heat, which is a type of infrared light. This makes lead telluride helpful in things like night vision cameras or sensors that measure temperature without touching.
Safety Information
It's important to handle lead telluride carefully. If it mixes with strong acids, it can create other substances that are not safe. Always make sure to follow safety rules when working with chemicals.
