Synthesis of X-type Zeolite from Dealuminated Kaolin by Reaction with

X-type zeolite was synthesized from kaolin previously dealuminated through reaction with sulfuric acid at high temperature to raise its SiO2/Al2O3 ratio. All of the steps in the synthesis of X-type zeolite from dealuminated kaolin were studied. Parameters analyzed included temperature, time, stirring speed, and composition ratios. The optimum values for the …

Chamotte for the production of ceramics and refractories

Clay minerals, such as kaolinite, are alumino-silicate hydrates and can be represented by the chemical formula Al 2 O 3.2SiO 2.2H 2 0. When heated ("fired"), these hydrates lose water and transform to a combination of mullite (3Al 2 O 3.2SiO 2), cristobalite (SiO 2), and a glassy phase which constitutes chamotte.

Molochite (200 mesh)

Molochite is a pure white made-made granular material. The granules are hard and refractory. It is made by firing raw low-iron kaolin to very high temperatures (about 1500℃) to bring about maximum conversion of the clay crystal to crystalline mullite (usually 95%+). The latter has high mechanical stability and resistance to thermal shock.

Synthesis of Zeolite Y from Kaolin via hydrothermal method

Kaolinite, a mineral construct of AlO6 octahedral and SiO4 tetrahedral sheet, is mostly found in kaolin and is a preferable natural raw material to synthesize zeolite Y, due to its favorable SiO2 and Al2O3 concentration and low cost. Typically, kaolin has to be calcined at high temperature (700-900°C) to reduce its naturally high chemical ...
