New Way to Make Special Materials is Cleaner and Safer

Topic: Materials Science

Scientists from Japan and the US have found a new way to make special materials called functional oxides. This method uses lower temperatures and smaller particles, making it safer for people and the environment.

Functional oxides are used in many modern technologies like electronics and energy-efficient systems. They have unique properties like superconductivity and magnetism that make them very useful. However, making these materials is often a problem because it requires harsh chemicals and high temperatures, which can be bad for people's health and the environment.

A team of researchers led by Takumi Nishikubo from Institute of Science Tokyo and Kenneth R. Poeppelmeier from Northwestern University in the US has developed a new way to make these materials. They published their study in the Journal of the American Chemical Society on June 18, 2026.

The researchers found that they could make a material called BiNi₁₋ₓFeₓO₃ using a process that combines two steps: reverse coprecipitation and oxidation. This process uses a metal nitrate solution mixed with an alkaline sodium hypochlorite solution to create a highly oxidized amorphous precursor. The resulting material is already highly oxidized, so it doesn't need any external oxidants.

The researchers were able to synthesize the target oxide at a lower temperature of around 750°C (1,380°F) in less than one minute under high-pressure conditions. This is much faster and safer than traditional methods that require higher temperatures and multiple steps.

The new method also allows for more control over particle sizes, which can be important for certain applications.

Why It Matters
