Information

The three common crystal forms of Calcium Carbonate are calcite, vaterite and aragonite. Among them, aragonite-type Calcium Carbonate whiskers are a new type of needle-like or spindle-like material discovered in recent years. At present, the commonly used methods for preparing Calcium Carbonate whiskers include: carbonization, urea hydrolysis, metathesis, etc.

But the above-mentioned methods all have certain deficiencies, such as: the reaction temperature is too high, the morphology of the whiskers is not uniform, and the raw materials cannot be recycled. In terms of application, compared with the common SiC and potassium titanate whiskers in the market, Calcium Carbonate whiskers have unique advantages, such as high whiteness, large filling amount, low cost, etc., and have been used in paint coatings, plastics, rubber, friction, etc. materials, etc.
