Method of manufacturing lightweight ceramics
The present invention discloses a method of manufacturing lightweight ceramics by mixing several raw materials such as a powdered glass material, a powdered alkali silicate, and a water-soluble polymer in a certain proportion to form a dry substrate, and then adding water to mold the substrate into a desired shape; after the water in the substrate is baked dry, heat the substrate until the ceramic is formed. The oxide and hydroxide in the alkali silicate are used to lower the softening point of the powdered glass material, and when the powdered glass material is in the semi fluid state, the air and crystal water brought by the alkali silicate will expand and form air bubbles due to the high temperature. In the meantime, the water-soluble polymer at the high temperature will also be converted into a gas which will escape and form close pores inside the finished goods, and pores with open passages on the surface of the finished goods, such that the finished goods will have the lightweight, insulating, refractory, and water-resisting features.
