As nouns the difference between kaolinite and kaolin is that kaolinite is mineralogy a common hydrous aluminosilicate mineral found in sediments soils and sedimentary rocks al 2 si 2 o 5 hydroxide oh 4 one of the kaolin group of minerals while kaolin is a fine clay rich Kaolin china clay is a hydrated aluminum silicate derived from the mineral Kaolinite Kaolin is chemically inert clay with a low shrink swell capacity well suited to a wide range of industrial uses including ceramics paper glass fiber filler paints wire and cable and plastics

From a purely physical properties point of view halloysite is a clay mineral similar to kaolin in firing and raw appearance In fact it normally occurs with kaolin deposits because kaolin is the pre eralogical analysis of these two minerals in the same clay is difficultWith the exception of porcelain like halloysite the sample must usually be analyzed in the laboratory to detect the presence of halloysite

Kaolin is a rock or sedimentary deposit rich in kaolinite and other very similar clay minerals such as dickite and halloysite which require X ray analysis for identification as well as other impurities The last sentence of the first paragraph sums it up but could perhaps be expanded a bitHalloysite is an aluminosilicate clay exhibiting a rare naturally occurring hollow tubular structure Halloysite tubes have a length in the range of 05 30 microns an exterior diameter in the range of 50 70 nanometers and an internal diameter lumen in the range of 15 30 nanometers
