PURPOSE: Provided is a method for forming zeolite, illite and bentonite, raw materials for bricks, tiles and pottery, without the addition of water and binder. Therefore, the compacts excluding water and air have no transformation and low water absorption. CONSTITUTION: The dry forming of powder materials is characterized by mixing 10-30wt.% of zeolite(800-1000mesh) for sterilization and deodorization with 10-30wt.% of illite(50-1000mesh), adding 40-70wt.%of bentonite, and pressing the mixed powder under pressure of 170-200kg/cm¬2. Also, the powder materials containing kaolin or yellow soil are mixed and pressed for compacts with less than 10% of water content.
