In 2002, our co***ny built the first production line of nano calcium carbonate powder in the world, which is synthesized by hyper-gravity method. The hyper-gravity technology produces gravitation acceleration by rotation. The acceleration is hundreds times higher than the earth¡¯s gravitational acceleration, and so in this super gravity environment, the chemical and crystallization processes can be effectively controlled through the control of molecular scale. Thus, we can produce the high-quality nano calci...
