KY method is a synthetic sapphire and the following is its preparation process and advantages:

Preparation Process of grow sapphire boule:

Raw Material Preparation: Aluminum oxides are mixed with appropriate amounts of blue colorants (usually iron and titanium) to form the chemical composition of the sapphire.

Melting: The raw materials are melted at high temperatures, usually using an oxy-acetylene flame or other high-temperature melting equipment.

Crystal growth: The molten material is gradually lifted into larger sapphire crystals by the Verneuil process.

Cutting and Polishing: Sapphire crystals are cut and polished to make sapphire wafers, sapphire optical windows, sapphire pillars, sapphire domes, sapphire rods, sapphire bearings, sapphire balls, sapphire nozzles, sapphire blanks, and more.

Advantages of sapphire material boule:

1.Control of composition: The synthesis process allows precise control of the chemical composition of the sapphire in order to obtain the desired color and purity.

2.Large sizes: The Lift-off method allows the preparation of large sapphire crystals for large gemstones and industrial use.

3.Lower cost: Synthetic sapphire is usually cheaper to prepare than natural sapphire and can be produced on a large scale.

4.Controllable color: By adding different colorants, sapphires of various colors can be prepared to meet the market demand.

5.The preparation process and advantages of Lira method sapphire crystals make it an important synthetic gemstone material, widely used in jewelry and industrial fields.
