Gradient gradient composite technology ceramic brick used in the field of glass kiln and its preparation method

Abstract

The invention discloses a ceramic brick with gradient gradient composite technology used in the field of glass kilns. On the basis of zirconia as the base material, other components are added to form the first layer of materials with a mass percentage of 100. After compounding, The content of this material is gradually changed step by step, and the content of other materials is gradually increased to the presence of trace zirconium dioxide. Two or more kinds of other materials are gradually increased and different components are changed to form multiple layers. Implementation of cloth for multi-layered components of 100 counts with a continuous gradient from one side to the other; components included: Zirconium Dioxide Zr0 2 , SiO2 2 , Diyttrium trioxide Y 2 0 3 , calcium zirconate eutectic CaZrO 3 , Barium zirconate eutectic BaZrO 3 , Magnesium-zirconium eutectic MgZrO 3 , Corundum α‑Al 2 o 3 , alumina powder α‑Al 2 o 3 , Alumina fiber whiskers α‑Al 2 o 3 , silicon carbide SiC, silicon nitride Si 3 N 4 , Magnesium oxide MgO. The preparation method is easy to operate and includes steps: 1. Raw material components: 2. Process treatment of components in each layer; d. Sintering of shaped products.

Description

technical field [0001] The invention relates to a gradient gradient composite technology ceramic brick used in the field of glass furnaces and a preparation method thereof. Background technique [0002] As an important inorganic material, glass products have been widely used in many technical fields such as science and technology, national defense and civil industry, electronic technology, semiconductor, optics and so on. Such as infrared transparent window materials, substrate substrates in the field of microelectronics, laser substrates, optical components, mobile phone screen glass and other uses. At present, the glass industry pool kiln used for glass manufacturing is used in China and the global glass industry. All domestic and international glass kilns use fused zirconium corundum bricks, also known as AZS. The English abbreviation of fused zirconium corundum bricks is AZS, for example No. 33 fused cast zirconium corundum brick, abbreviated as AZS-33#, No. 36 fused ca...

Problems solved by technology

Due to the existence of the glass phase, under long-term constant high-temperature working conditions, the glass phase reacts and scours with certain substances in the glass liquid, resulting in the loss of the liquid phase of the glass phase, scour adhesion, and the opening of the porosity. The corundum and zircon are eroded and eroded by the solution and low-soluble substances, resulting in intensified damage to the brick body. The corundum and baddeleyite are continuously lost and lost in the glass solution along with erosion and scouring. When the scouring and erosion reach a certain degree or the cause of erosion caused by high-temperature active chemical reactions, it is necessary to stop production and replace with new kiln electric fused bricks. Not only is the cost high, but also the loss of production and maintenance is huge, causing huge cost difficulties for glass product manufacturers.
