6mm Thickness Sapphire Crystal Watch Case

Bright Yellow Color Sapphire Crystal Watch Case With Square Shape

Czochralski method, or CZ method for short. First heating the raw material to the melting point and then melting to form a melting soup, and then using a single crystal seed to contact the surface of the melting soup, in the crystal seed and the solid liquid interface of the melted soup due to the temperature difference and formed too cold. So the melted soup began to solidify on the surface of the seed and grow a single crystal with the same crystal structure as the seed. The seed is also pulled up at a very slow speed, and accompanied by a certain speed of rotation, with the upward pull of the seed, the melt soup gradually solidified on the liquid solid interface of the seed, and then formed a axis of symmetrical single crystal ingot.

FATURES

1. High mechanical strength: the permeable infrared window material should have sufficient strength to withstand the high-speed movement of the speed pressure load;

2. Good thermal stability: the permeable infrared window material should be able to withstand the temperature shock caused by pneumatic heating and height changes, transmission ratio and refractive index should not change significantly with the change of temperature;

3. Good chemical stability: through infrared window material exposed to air, should be able to prevent the atmospheric salt solution or corrosion gas corrosion, and not easy to moisture;

4. High optical transmission rate, must be able to effectively transmit ultraviolet to medium infrared radiation;

5. Good optical characteristics, small optical scattering and good uniformity of refractive index;
Meets large window requirements.
