What is BeO? Important knowledge about BeO.

1. Definition of BeO
   BeO, also known as beryllium oxide, is a chemical compound belonging to the oxide category of the metal beryllium. The atomic mass of BeO is 25.01, wherein Be accounts for 9.01, and O is 16. The molecular structure of BeO includes one beryllium atom (Be) and one oxygen atom (O). BeO has an ionic structure with beryllium ions and oxygen ions.

2. Properties of BeO
   2.1 Physical properties of BeO
   BeO is a colorless, odorless solid substance, and it does not have a sour or alkaline taste (Neutral pH).
   2.2 Chemical properties of BeO
   BeO is insoluble in water and most common solvents. It only dissolves in strong acid or strong alkali solution.

3. Commonly encountered chemical equations of BeO

   • Be + O₂ -> BeO
   • 2Be + O₂ -> 2BeO
   • 2BeO + SiO₂ -> 2BeSiO₃
   • BeO + 2HCl -> BeCl₂ + H₂O
   • 2BeO + C -> 2Be + CO₂

4. Synthesis of BeO
   4.1 Laboratory synthesis of BeO
   BeO is usually synthesized from the reaction between beryllium and oxygen in the air.

   • Chemical reaction: 2Be + O₂ -> 2BeO
     4.2 Industrial synthesis of BeO
     In industry, BeO is typically produced from the process of melting beryllium carbonate at high temperatures.
   • Chemical reaction: BeCO₃ = BeO + CO₂ ->

Note: BeO can be toxic if inhaled, swallowed, or comes in contact with skin and eyes. Therefore, protective glasses, gloves, and coats should be worn when working.
