Hydrotalcite CAS 11097-59-9

Co-precipitation method: This method is the most commonly used synthetic talc, the soluble divalent or trivalent metal ion salts (can be nitrate, sulfate, chloride) mixed into a metal salt solution in a certain ratio, and then adjust the PH with alkali (can be sodium hydroxide, ammonia carbonate, or urea), wait until the white water talc colloidal soluble material, and then crystallized, washed, dried, ground to get water talc.
