Alumina ceramic membrane sintering aid as well as preparation method and application thereof
The invention discloses an aluminum oxide ceramic membrane sintering aid as well as a preparation method and application thereof, and relates to the technical field of ceramic membranes. The foaming powder is prepared from 20 parts of aluminum oxide powder, 50 to 80 parts of potassium feldspar, 5 to 20 parts of albite, 0.1 to 1 part of sodium carboxymethyl cellulose, 0.1 to 1 part of sodium tripolyphosphate, 0.5 to 3 parts of sodium hexametaphosphate, 0.3 to 1 part of 1000-mesh manganese dioxide, 0.1 to 0.6 part of 1000-mesh silicon carbide and 100 parts of water. The granularity of the alumina ceramic membrane sintering aid is controllable, and the temperature is controllable when the alumina ceramic membrane sintering aid is applied to the preparation process of an alumina ceramic membrane support; in the preparation process of the aluminum oxide ceramic membrane support, the nano silicon dioxide in the sintering aid can adjust the viscosity of a high-temperature liquid state and accelerate the reaction of the sintering aid and the aluminum oxide powder at the same time, a large bridging effect is achieved, and the porous liquid state at the high temperature can ensure the strength of the aluminum oxide ceramic membrane support and increase the porosity at the same time.
