Crystal Ingot Block is a crystal block manufactured based on high-purity materials, with the core being the formation of a single crystal structure through precision controlled growth processes. This type of crystal block typically has a uniform internal structure and is one of the fundamental materials in high-end semiconductor and optoelectronic fields. As an important form of crystal material, Crystal Ingot Block needs to undergo strict quality testing during the production process to ensure high standard requirements for subsequent processing. It is not only the cornerstone of modern industrial technology development, but also a key raw material for achieving high-performance electronic devices and optical components. Its shape is usually a regular geometric shape, which facilitates subsequent cutting, grinding, and polishing processes.

This quality stability provides customers with reliable assurance.

1. Raw material preparation:

The first step in producing Sapphire Crystal Ingot Block is to select high-purity aluminum oxide (Al₂O₃) as raw material. These raw materials need to undergo rigorous purification to remove any impurities that may affect the quality of the crystal. Only aluminum oxide with a purity of more than 99.99% can enter the next stage.

2. Crystal growth technology:

The core production link of Sapphire Crystal Ingot Block is crystal growth, usually using the Czochralski method or the Kyropoulos method. In this process, aluminum oxide powder is heated to a molten state and then slowly crystallized through a precisely controlled cooling rate to form a single crystal structure. The entire process needs to be carried out in a dust-free environment to avoid external contamination.

3. Temperature and environmental control:

The stability of temperature and environment is crucial during the crystal growth process. Plutosemi uses advanced temperature control systems and inert gas protection devices to ensure that the molten liquid is under constant temperature and pressure conditions. This fine control can effectively prevent bubbles or cracks from appearing inside the crystal.

4. Crystal annealing:

In order to eliminate the residual stress inside the crystal, the Sapphire Crystal Ingot Block needs to be annealed after the growth is completed. This process releases the thermal stress inside the crystal by gradually reducing the temperature, thereby improving the overall mechanical properties of the material.

5. Cutting and shaping:

After the crystal growth is completed, the original crystal ingot will be cut and shaped according to customer needs. Plutosemi is equipped with high-precision cutting equipment that can process the crystal ingot into blocks or sheets of various specifications while ensuring a smooth and flawless surface.

6. Quality inspection:

Each Sapphire Crystal Ingot Block needs to undergo multiple quality inspections before leaving the factory, including optical performance tests, mechanical strength tests, and chemical stability assessments. Only products that fully meet the standards will be delivered to customers.

7. Packaging and transportation:

Finally, the finished product will be properly packaged to prevent damage during transportation. Plutosemi uses professional shock-proof and moisture-proof packaging solutions to ensure that the product arrives safely in the hands of customers.
