Abstract

The invention comprises pelletized particulate material which is self-bonded and has a principal phase consisting of synthetic mordenite. The pellets may be formed from a powdered aqueous mixture having a molar composition of Na2O. 1 to 1.33 Al2O3. 8.5 to 11 SiO2 excluding water fired at a temperature high enough to produce self-bonding but not complete vitrification, e.g. 600 DEG C. for 1 hour, and heated at a reduced temperature with an aqueous solution of sodium silicate or caustic soda or a mixture thereof. The initial mixture may be prepared from kaolin, diatomaceous earth, sodium silicate, and water. A typical composition comprises 19.15% kaolin, 26.57% diatomaceous earth, 54.28% aqueous sodium silicate, and 7.7% water. The final heating of the pellets may be effected at a temperature below 290 DEG C. When this temperature is 200 DEG C. or less, the pellets, on being refluxed with strong acid, undergo ion exchange, sodium ions being replaced by hydrogen ions.
