The role of magnesium oxide in ceramic art is mainly reflected in the following aspects

The role of magnesium oxide in ceramic art is mainly reflected in the following aspects:

Enhancer:

Magnesium oxide has a high melting point and melting temperature,making it an excellent ceramic reinforcement material.Adding an appropriate amount of magnesium oxide during ceramic preparation can increase the sintering temperature and density of ceramics,thereby enhancing their strength and hardness.For example,in the preparation of alumina ceramics,silicon nitride ceramics,etc.,adding an appropriate amount of magnesium oxide can significantly improve the hardness and wear resistance of ceramic materials,while improving their high temperature resistance and electrical insulation performance.

Magnesium oxide reacts chemically with other components in ceramic materials to generate new compounds that can fill micro defects in ceramic materials,enhance their density and hardness,and exhibit better performance in friction and wear.

Flame retardant:

Magnesium oxide is an excellent flame retardant material with high melting point and high temperature resistance.Adding magnesium oxide to ceramics can improve their fire resistance and enhance their flame retardant properties.This is very important for ceramic products that require fire resistance and high temperature resistance,such as building tiles,fireproof boards,etc.

Stabilizers:

Magnesium oxide has a low coefficient of thermal expansion,which can help regulate the coefficient of thermal expansion of ceramics,thereby reducing cracking and deformation caused by temperature changes.During the high-temperature firing process of ceramic products,magnesium oxide can slow down the thermal expansion of ceramics,improve their thermal stability,and reduce the occurrence of thermal shock cracks.

Whitening agent:

Due to the high whiteness and light reflectivity of magnesium oxide,an appropriate amount of magnesium oxide is added to some ceramic products that require whitening effects.The whitening effect of magnesium oxide can enhance the overall appearance of ceramic products,making them more aesthetically pleasing and ornamental,such as daily-use ceramics,sanitary ware,etc.

Toughening agent:

Ceramic products are generally brittle and have poor impact resistance,but adding an appropriate amount of magnesium oxide can improve the toughness and impact resistance of ceramics.This makes ceramic products more durable and less prone to breakage during use.

Glaze flux:

Magnesium oxide is commonly used as a stabilizer and flux in ceramic glazes.It can increase the melting point of the glaze,making it less likely for the glaze to flow during high-temperature firing,thereby improving the appearance quality of ceramic products.In addition,magnesium oxide can improve the anti glaze cracking performance of glazes,enhance the wear resistance and hardness of ceramic products.

Affects color and transparency:

Magnesium oxide can affect the color and transparency of ceramics,providing more choices for ceramic design and production.For example,in the production of tiles and ceramic tiles,magnesium oxide can affect the texture and brightness of the tiles;In the field of optical ceramics,adding magnesium oxide to ceramic materials can prepare optical components with high transmittance and low scattering.

In summary,magnesium oxide plays an important role in ceramic art,affecting the performance,appearance,and service life of ceramics in different ways,providing strong support for the development of ceramic art.
