(stock number 8463) In the semiconductor industry, hydrofluoric acid is used for cleaning and chip etching during the manufacturing process, resulting in wastewater containing hydrofluoric acid etchant. After undergoing chemical coagulation, precipitation, and dehydration treatment, calcium fluoride sludge is generated. Calcium fluoride can serve as a mineralizer in cement production, thus the calcium fluoride sludge can partially substitute some cement ingredients. Using the by-products contained in calcium fluoride sludge from the cement process, such as silicon oxide, aluminum oxide, calcium oxide, etc., after appropriate blending, followed by grinding, mixing, and high-temperature firing in a rotary kiln (more...)
