Borates In Glass: Making Great Technology Even Better

Glass is one of our oldest and most well-engineered technologies. It is also one of the most promising contemporary technologies. This material is essential in many of our daily products. Through ongoing research, process adaptations, and industry partnerships, glass producers are helping to ensure that this versatile material has a long-term future.

Borates are part of it all. Borosilicate glass is essential for modern applications because of its strength, resilience, and resistance to chemicals, scratches, and thermal shock.

Today glass producers add 5-20% boric dioxide to the silica-based to reduce melting temperature and viscosity. This helps to inhibit crystallization and thermal expansion and devitrification. The result is a product that has inherent durability and chemical resistance and can withstand substantial mechanical or thermal shock.

Modern Glass Producers Use Borates To Make A Wide Range Of Products.

  • Borosilicate glasses are used in applications ranging from pharmaceutical production to cookware and lighting
  • Insulation fiberglass is used for energy saving in buildings
  • Superfine Glass Fiber (micro fiberglass) is used for filtration papers, battery separators, insulation panels, and equipment insulation.
  • Polyester fiberglass (E-glass), used in electronics and as reinforcement for composites
  • Display glasses, which include thin-film transistor (TFT), as well as liquid crystal display (LCD).
  • Special glasses include optical and technical glass and heat-resistant tubes of borosilicate.
  • Manufacturers need to ensure that these products meet all requirements, from industry compliance and government compliance to customer specifications.

Quality Begins With Inputs: Benefits From Refined Borates

To maintain consistency and quality, glass manufacturers monitor and inspect every step of the process from the preparation of raw material to the melting process to the forming, annealing, finishing.

There may be differences in the quality control standards and methods across different glass types. Display glass must adhere to strict standards regarding its optical properties and visual appearance. Insulating glass is more flexible. However, it doesn’t matter which application you use, the glass manufacturing industry requires traceability and quality of raw materials (including borates).

It is essential to have consistent, high-quality borates because changes in raw materials can impact the glass’s chemical and physical properties. The glassmaker must be certain that the materials used in their formulations deliver consistent levels of boron and work the same in every melt.

The traceability of raw materials is essential. Glass manufacturers must be able to verify the origin of their borate products, as well as confirm how they were refined, packaged, and processed. This helps manufacturers comply with regulatory requirements and allows them to fix quality problems before they reach end customers.

To Improve Process Efficiency And Sustainability, You Must Use Your Resources Effectively

Refined Borates allow for better recycling of glass in glass manufacturing. Cullet, which is 15% of the recycled glass waste, is added to the glass melt. This benefits the environment, reduces energy consumption, and helps lower costs. The most common consumer of cullet is insulation fiberglass, which is a boron-containing type.

Unfortunately, recycled glass can be limited due to borosilicate current availability, limitations on glass formulations, and contamination. It is common practice to add refined borates to non-boron containing cullet. This allows manufacturers to optimize the raw materials mix and control the quality of the melt.

Glass manufacturers are constantly improving their products through practical optimizations such as these. Many organizations strive to improve the industry’s future. You can contact a zinc borate supplier that will provide you with the fined product of borates.
