Understanding Boric Acid and Its Critical Role in LCD Glass Manufacturing

What is boric acid? At its core, boric acid is an inorganic compound that serves as a key raw material in advanced glass applications, particularly in the production of LCD displays. Its unique chemical properties—including precise impurity control, controlled moisture content, and optimized particle size distribution—make it indispensable for manufacturing high-precision LCD glass that meets stringent industry standards.

5E Advanced Materials Achieves Major Commercial Breakthrough

5E Advanced Materials, Inc. (trading as FEAM) has reached a significant milestone in its commercialization journey by successfully completing a large-scale 20-ton production trial of boric acid with a major U.S. LCD glass manufacturer. This achievement represents far more than a routine test—it validates the company’s ability to scale production while maintaining the exacting quality standards required by the advanced glass industry.

The comprehensive qualification pathway spanned several critical phases. Laboratory testing commenced in April 2025, followed by supply-chain validation completed in August. The commercial-scale production trial, which launched in December 2025, demonstrated that 5E’s boric acid consistently meets all essential specifications. These include precise impurity levels, moisture content parameters, particle size distribution requirements, and reliable logistics performance—each crucial for seamless integration into high-precision LCD glass manufacturing workflows.

Strategic Importance in the Boron Supply Chain

The timing of this commercial validation carries strategic significance. The U.S. Department of the Interior’s recent designation of boron as a critical mineral in 2025 underscores the nation’s growing vulnerability regarding raw material supply chains. This classification highlights the urgent need for domestic producers capable of supplying refined borate materials to fast-growing industrial sectors.

5E’s successful trial positions the company as a potential cornerstone in establishing a more resilient, domestically-focused supply chain for advanced boron materials. By demonstrating production reliability and quality consistency at commercial scale, the company moves closer to securing an initial offtake agreement with its LCD glass partner—a pivotal step toward sustained commercialization.

Market Response and Industry Outlook

FEAM shares have appreciated 7.5% over the past six months, reflecting investor confidence in the company’s commercialization progress. This performance gain occurs against a broader industry backdrop that has seen more modest returns, underscoring the market’s recognition of 5E’s competitive positioning in the boron materials sector.

The successful completion of this trial delivers the customer approvals and operational validation necessary for 5E to establish itself as a reliable supplier to advanced industrial applications. As domestic demand for refined borates and specialty boron materials intensifies alongside broader supply chain diversification initiatives, 5E’s achievement represents a meaningful step toward capitalizing on this emerging opportunity.

The convergence of technical validation, strategic supply-chain importance, and growing industrial demand creates a compelling backdrop for companies successfully navigating the path from pilot production to full-scale commercial deployment in the boron materials space.
