Yuanlei Classroom | As a key material, how many applications does precipitated barium sulfate have?

2024-07-11


The appearance of precipitated barium sulfate is a white amorphous powder, with a relative density of 4.50 (15 ℃) and a melting point of 1580 ℃. Due to its high refractive index (1.63-1.65), it exhibits a relatively white color and a certain degree of covering power. It is almost insoluble in water, ethanol, and acid, soluble in hot sulfuric acid. It is easy to form mixed crystals with potassium permanganate, calcium carbonate, or metal nitrates, and can be reduced to barium sulfide with carbon at high temperatures.

Wet mica powder is a high-quality mineral filler made from high-quality mica raw materials, which are washed, impurity removed, soaked, crushed, low-temperature dried, and screened. Its unique production process maximizes the preservation of mica's sheet-like structure, large diameter to thickness ratio, high refractive index, high purity, high whiteness, high gloss, low sand and iron content, and other industrial characteristics that cannot be compared to dry process technology. The unique performance of wet mica powder has greatly improved its application in multiple industries such as plastics, paint, rubber, etc., and has a significant effect on improving product performance and reducing costs.
