5E Advanced Materials Inc. announced that a major domestic LCD glass manufacturer has begun testing with the company's boric acid, following the shipment of twenty tons of the material. This marks the final phase of product qualification, with results expected before the end of the year. The company reported that the boric acid met the customer's specifications and performed well during initial integration into the glass furnace. This follows prior successful laboratory bench testing and a supply-chain trial involving a two-ton shipment. The company noted that completion of this trial could position 5E to pursue multi-year supply agreements in the LCD glass sector.
