Chinese scientists developed safe, cheap, durable rare-earth pigments to replace toxic ones in consumer products.
Researchers in Northeast China have created eco-friendly pigments using abundant rare earth elements, offering a safer, more durable, and up to 60% cheaper alternative to toxic heavy-metal pigments.
By stabilizing rare-earth ions in a silicoaluminate host through over 1,000 experiments, they achieved vibrant, fade-resistant colors in green, yellow, orange, and red that withstand heat, sunlight, and aging.
A pilot production line is set to open in Liaoning province, aiming to replace hazardous pigments in toys and household goods, advancing public safety and environmental sustainability.
