In this work detergent-grade zeolite A has been synthesized from the Ethiopian kaolin collected from the southern part of the country with the molar gel composition of Na 2 O:Al 2 O 3:2SiO 2:37H 2 O. Two routes are surveyed for the synthesis of zeolite A: alkali fusion using raw kaolin and conventional hydrothermal synthesis.

1. Introduction. Kaolin is a white-brown powdery clay mineral. It has the main constituent of kaolinite of a hydrous aluminum silicate (Al 2 O 3.2SiO 2.2H 2 O) with a single tetrahedral silicate layer linked via oxygen molecules to a single alumina octahedral layer. The most common auxiliary minerals found with kaolin are maternal rocks such as …
