"Haifa SILICA SAND – Container - 150" – Silica Sand for manufacturing container glass.

The production of container glass, such as bottles and jars, typically requires a specific type of silica sand known as soda-lime silica sand. This type of silica sand is the most common and widely used in the glass manufacturing industry. Here are the key characteristics and requirements for the silica sand used in the production of container glass: Solar-grade silica sand is characterized by its high purity, low iron content, and specific size distribution. Here are some key requirements for the silica sand used in PV glass production:

Soda-lime silica sand should have a high silica content, typically around 70-75%. Silica (SiO2) is the primary component of glass, providing its structural integrity.

 Soda (sodium carbonate) and lime (calcium oxide) are essential additives in container glass manufacturing. Soda helps in lowering the melting temperature of the glass mixture, while lime improves its chemical resistance. The levels of soda and lime are controlled to achieve the desired glass properties.

Iron impurities can impart a greenish tint to the glass, which is undesirable in container glass. Hence, the silica sand should have a low iron content, typically less than 150 parts per million (ppm) or even lower.

 The particle size distribution of the silica sand is important for achieving consistent glass quality. It is often necessary to have a controlled range of particle sizes to ensure proper melting and forming of the glass during the manufacturing process.

 Other impurities such as alumina, titania, and other metal oxides should be minimized to maintain the desired clarity and quality of the container glass.

It's important to note that different glass manufacturers may have slight variations in their specific requirements for silica sand based on their production processes and desired glass properties. However, soda-lime silica sand is the most commonly used type for container glass due to its availability, cost-effectiveness, and compatibility with the manufacturing processes involved in container glass production.
