Product Description


White flake crystal powder, a sense of greasy, earthy taste.
Relative density: 2.58. PH value (20% water suspension) 3.8 ~ 7.5.
Mohs hardness: 2.0
Oil absorption rate: 40% ~ 50%.
Average particle size: 0.5 to 1 micron.
Maximum free water: 1.0%.
Calcined kaolin is characterized by high whiteness, small bulk density, large specific surface area and pore volume, good oil absorption, covering and abrasion resistance, high insulation and thermal stability.
1, chemical stability, kaolin has good acid solubility.
2. Cation exchange capacity. The cation exchange capacity of kaolin refers to the total amount of cations exchanged by kaolin under the PH value of 7, including exchangeable base and exchangeable hydrogen, with the unit of mmol/g, that is, the cation exchange capacity exchanged per 1g dry sample is generally 0.03-0.05mmol/g.
3. Refractoriness: kaolin is chemically composed of Al2O3 and SiO2, so it has excellent fire resistance with a refractoriness of 1770-1790ºC.
