Low expansion molecular sieves bodies and method of making them which involves forming a mixture of up to about 40 weight parts of a thermal expansion control component which can be at least one of zircon, feldspar, calcium silicate, talc, steatite, forsterite, kyanite sillimanite, nepheline syenite
Low expansion molecular sieves bodies and method of making them which involves forming a mixture of up to about 40 weight parts of a thermal expansion control component which can be at least one of zircon, feldspar, calcium silicate, talc, steatite, forsterite, kyanite sillimanite, nepheline syenite, glasses, about 10 to 30 weight parts of permanent binder, at least 50 weight parts of molecular sieve, and temporary binder which can be cellulose ethers, cellulose ether derivatives, and combinations thereof, in a vehicle. The mixture is shaped into a green body which is then dried and fired to produce the product body. Among the preferred bodies are zeolites which find use in hydrocarbon adsorption, denox, and three-way catalyst applications.
