Bauxitic kaolins, compositions comprising the same, and methods of making and using the bauxitic kaolins are disclosed herein. The bauxitic kaolins can have an Al2O3 content of greater than 50% to 85% by weight (on a calcined basis), a loss on ignition of at least 17% by weight, and a surface area of at least 100 m2/g, as determined by a Micrometrics Gemini 2370 surface area analyzer. The bauxitic kaolins can be used in various applications depending on their average particle size and/or particle size distribution as well as other desired properties. In some embodiments, the bauxitic kaolin can be used as a flame retardant filler in applications such as carpets and plastics or as an adsorbent. |
