Explanation

Also known as high-temperature decomposition method. It is a method of using a certain compound to decompose under high temperature conditions and provide the required precipitate vapor for crystal growth. It belongs to the chemical vapor precipitation method in growth from vapour phase. It is commonly used to grow crystal of silicon and germanium. It is seldom used for the growth of compound crystal - because when the reaction contains a single input substance (except for transport gas) - the products obtained by controlling 1 according to the ideal ratio are greatly limited. In order to grow crystal by pyrolysis method, appropriate pyrolysis compounds should be selected first. This compound cannot be too stable and easy to volatilize. It can decompose and generate this sediment under conditions near the growth zone. Generally, the reaction temperature should be lower than the melting point of the crystal of the sediment.
