​​Soda-Lime Glass Silicate Glass Substrates Customized Size/Shapes​​

1. Transparency​​: High clarity and light transmittance, making it suitable for window glass and containers.
2. ​​Ease of Processing​​: Relatively low melting temperature, allowing easy shaping and processing.
3. ​​Chemical Stability​​: Stable against many chemicals, but exhibits weaker resistance to strong acids and alkalis.
4. ​​Thermal Expansion​​: Prone to cracking under sudden temperature changes due to its relatively high thermal expansion coefficient.

1. Cost-Effectiveness​​: The relatively low price of soda-lime glass makes it economically advantageous in grinding and polishing processes requiring large material quantities.

​​

  2. Ease of Processing​​: It demonstrates good processability, enabling desired surface quality and precision to be achieved efficiently through grinding and polishing.

​​

  3. Stability​​: Under appropriate processing conditions, soda-lime glass provides stable grinding and polishing results, ensuring consistency and reliability in the machining process.

The Principle of Soda-Lime Glass Manufacturing Process

The manufacturing of soda-lime glass involves using quartz sand (SiO₂), soda ash (Na₂CO₃), and limestone (CaCO₃) as core raw materials. These are melted at approximately ​​1500°C​​ to form a uniform silicate glass melt through chemical reactions. This molten glass can be shaped by methods such as manual blowing, or mechanical processes like the float glass process and pressing. Subsequently, the glass must undergo ​​annealing​​—a process of controlled slow cooling typically within the ​​400–600°C​​ range—to eliminate internal stresses and enhance its stability.

In essence, the fundamental process for soda-lime glass is a continuous sequence of ​​"Batching → Melting → Forming → Annealing"​​. Its characteristics of low cost and ease of forming make it the most widely used type of glass in everyday applications.
