This article discusses preventing yellowing in quartz sand after hydrofluoric acid washing. Key strategies include starting with high-purity quartz, optimizing acid concentration, controlling exposure time and temperature, and ensuring thorough post-treatment rinsing. These measures maintain crystal clarity for various industrial applications.

Sodium bifluoride (NaHF2) enhances metal quality and adhesion in aluminum, titanium, magnesium, and steel. It removes oxides and offers controlled etching, but safety precautions are crucial due to its corrosiveness. Understanding its applications and principles is vital for metal surface quality.

Ammonium Bifluoride plays a pivotal role in the electronic industry, contributing to processes that shape the components and devices we rely on daily.
