Magnesium fluoride (MgF ₂) crystals, as a high-quality optical material, are widely used in various fields such as optical instruments, lasers, and infrared windows. In these applications, the surface quality of magnesium fluoride crystals is crucial, so polishing technology has become an indispensable part of magnesium fluoride crystal processing.
The purpose of polishing magnesium fluoride crystals
The purpose is to remove scratches, burrs, and uneven defects on the surface of the crystal, making it smooth and even, in order to improve the optical performance of the crystal. The polished magnesium fluoride crystal has higher transparency and lower scattering loss, which can provide better optical effects.
The method of polishing magnesium fluoride crystals
There are two main methods for polishing magnesium fluoride crystals: mechanical polishing and chemical polishing.
1. Mechanical polishing: Mechanical polishing is the process of friction and material removal on a crystal surface using polishing tools (such as polishing cloths, polishing wheels, etc.) and polishing solution. This method is suitable for removing rough surface defects and unevenness. During the polishing process, it is necessary to choose appropriate polishing tools and fluids, and control the polishing pressure and speed to avoid excessive wear and damage to the crystals.
2. Chemical polishing: Chemical polishing is the process of using chemical reactions to remove surface materials from crystals. Usually, chemical solutions containing oxidants or reducing agents are used to undergo chemical reactions on the surface of crystals, thereby removing the surface layer. This method is suitable for obtaining smoother and flatter surfaces. During the chemical polishing process, it is necessary to control the concentration, temperature, and polishing time of the solution to ensure consistency and stability of the polishing effect.
