Soda Feldspar: a key raw material for the optoelectronic display materials industry

In the optoelectronic display material industry, Soda Feldspar (NaAlSi3O8) is an indispensable raw material. With its unique physical and chemical properties and wide application value, it has become a key element in manufacturing high-performance optoelectronic display components. This article will start from the specific application of Soda Feldspar in the optoelectronic display material industry and deeply analyze its advantages as a raw material.

Application Analysis：

• Substrate glass manufacturing:

In the production process of liquid crystal display (LCD) and organic light-emitting diode display (OLED), substrate glass is the core component supporting the display layer. As one of the main components of substrate glass, Soda Feldspar has high purity, good melting property and chemical stability, which ensures that the substrate glass has excellent flatness, light transmittance and heat resistance. These properties are essential for improving the resolution, color saturation and service life of the display.

• Touch screen glass:

As a standard function of modern smart devices, touch screens place extremely high demands on the hardness, wear resistance and light transmittance of glass. The application of Soda Feldspar in touch screen glass helps to improve the scratch resistance and impact resistance of glass while maintaining good touch sensitivity and visual experience.

• Optical component manufacturing:

Optoelectronic display devices often contain various optical components, such as lenses, prisms, etc. These components require high light transmittance, low dispersion and high-precision processing. The high refractive index and low dispersion characteristics of Soda Feldspar make it an ideal material for manufacturing these optical components. In addition, the stability of Soda Feldspar also helps to ensure that the optical components maintain stable performance in long-term use.

Advantages Analysis：

• Excellent physical and chemical properties:

Soda Feldspar has a high melting point, high hardness, low expansion coefficient and good chemical stability. These properties make Soda Feldspar perform well in the high-temperature and high-pressure glass manufacturing process, and can resist thermal stress, chemical erosion and mechanical wear, thereby extending the service life of optoelectronic display products.

• Improve production efficiency:

The melting temperature of Soda Feldspar is moderate, the melting speed is fast, and the glass liquid after melting has good fluidity. These characteristics help to shorten the melting and molding time in the glass manufacturing process and improve production efficiency. At the same time, the uniform distribution of Soda Feldspar also helps to reduce bubbles and inclusions in the glass and improve the quality of the glass.

• Reducing costs:

Compared with other high-purity glass raw materials, Soda Feldspar has relatively abundant reserves and low mining and processing costs. This makes Soda Feldspar one of the competitive raw materials in the optoelectronic display material industry. In addition, by optimizing the ratio and processing technology of Soda Feldspar, the production cost can be further reduced.

Advantage Comparison：

• Advantages of Soda Feldspar over Quartz Sand:

Chemical Composition and Stability:

Compared to quartz sand, Soda Feldspar (NaAlSi₃O₈) contains a specific sodium element, which may be necessary in the formulation of some optoelectronic display materials to adjust the electrical, optical or thermal properties of the material.

Melting Characteristics:

The melting temperature of Soda Feldspar is moderate, and the glass liquid after melting has good fluidity, which helps to reduce energy consumption in the melting process and improve production efficiency. Quartz sand has a higher melting temperature, which requires higher energy consumption and longer melting time.

• Advantages of Soda Feldspar over Borosilicate Glass：

Processing Flexibility:

As a raw material, Soda Feldspar has higher processing flexibility. During the manufacturing process, the ratio and processing conditions of Soda Feldspar can be adjusted according to specific needs to prepare optoelectronic display materials with different properties. Borosilicate glass is a pre-formed material with relatively fixed properties and limited adjustment space.

Raw Material Characteristics:

Soda Feldspar has unique physical and chemical properties, which make Soda Feldspar have unique advantages in the manufacturing process of optoelectronic display materials. In contrast, the raw material properties of borosilicate glass may not be as outstanding as those of Soda Feldspar in some aspects.

In summary, Soda Feldspar has unique advantages and competitiveness in the optoelectronic display material industry. Its stable chemical properties, excellent melting characteristics, good optical properties and cost-effectiveness make Soda Feldspar one of the ideal raw materials for manufacturing high-performance optoelectronic display products.
