The Effect of Magnesium Oxide on the Surface Hardness of Glass Balls

The influence of magnesium oxide(MgO)on the surface hardness of glass spheres can be analyzed from the following aspects

The influence of magnesium oxide(MgO)on the surface hardness of glass spheres can be analyzed from the following aspects:

Increasing the hardness of glass:Magnesium oxide is commonly used as a flux or oxide additive in glass,which can effectively regulate the physical and chemical properties of the glass,including increasing its hardness.

Improving polishing efficiency:Magnesium oxide has good hardness and moderate particle size,which enables it to effectively remove small scratches and unevenness on the surface of glass balls during the polishing process.By controlling the particle size and concentration of magnesium oxide reasonably,higher polishing efficiency can be achieved.

Impact on surface quality:The surface of glass balls polished with magnesium oxide should have high smoothness and no obvious roughness or defects.The surface roughness(Ra value)should be minimized as much as possible to ensure precision.At the same time,the polished surface should be free of defects such as scratches and cracks.

Controlling crystallization performance:Adding magnesium oxide to optical glass can effectively control the hardening rate and crystallization performance of the glass liquid,mainly improving the high-temperature physical properties of the glass and enhancing its melting performance,playing a role in assisting melting.

In summary,magnesium oxide has a significant impact on the surface hardness of glass balls,and through reasonable use and control,the hardness and surface quality of glass can be effectively improved.
