Synthetic Sapphire Crystal Suitable For Sapphire Lens And Electrical Insulator​

Description

The research on synthetic sapphire has a long history, and the technology is constantly improving. The difference from natural corundum can be measured by basic gemological characteristics such as microscopic characteristics, dichroism and spectrum, and large instruments such as XRF can also be used for testing.

Specification

Hydrothermal method—Synthesis principle

The hydrothermal synthesis of sapphire further reduces the natural environment. Under high-pressure water-containing conditions, the crystal gradually crystallizes on the seed crystal.
Process flow
1. Put the raw materials and seed crystals into the autoclave containing water at the same time.
2. The water in the autoclave is heated to 200°C to make the water a hot and high-pressure dense fluid, thereby dissolving materials that cannot be dissolved under normal conditions.
3. Slowly cooling, the crystal grows on the seed crystal.

Identifying characteristics
1. External characteristics:
• Uniform color and high transparency
2. Internal characteristics:
• There are few internal inclusions, with jagged, corrugated or dendritic growth patterns, nail-shaped inclusions, yellow metal sheets, etc.
