Natural barite and anthracite containing more than 95% barium sulfate are mixed and fed at a ratio of 3:1 (mass). After being crushed to a diameter of less than 2cm, it enters the reduction furnace. The furnace temperature is controlled to be 1000-1200°C in the front section and 500-500 in the back section. 600°C, the reduction furnace rotates at a speed of 80 seconds per revolution, and the reaction conversion rate is 80% to 90%.
It is generally more expensive than lithopone and may not be as environmentally friendly It is generally more expensive than lithopone and may not be as environmentally friendlylithopone and titanium dioxide. The production process for TiO2 involves the use of hazardous chemicals, and its disposal can be problematic. Additionally, TiO2 has a tendency to agglomerate, which can affect its performance in certain applications.
