Rice hull ash is primarily composed of silica (about 90%) and carbon (about 10%). The research team has developed a method to extract high-purity silica from rice hull ash. “Once the silica is ...
In prior work, the research team demonstrated methods to partially remove the silica in rice hull ash which contains about 90% silica and 10% carbon. That silica can be used to produce high-purity ...
That silica can be used to produce high-purity silicon used in solar cells or semiconductors. Once the silica is partially removed from the rice hull ash through a process called depolymerization ...
