Gradient composite technology ceramic tile and preparation method thereof in field of glass kilns

Abstract

The invention discloses a gradient composite technology ceramic tile in the field of glass kilns, which is prepared by the following steps of on the basis of taking zirconium dioxide as a base material, compounding with other components to form a first-layer material with the mass percentage of 100%, gradually changing the content of the material by sections in a gradient manner and gradually increasing the content of other materials until a trace amount of zirconium dioxide exists, progressively increasing two or more than two other materials in a gradient manner and changing different components to form a plurality of layers of components in percentage by mass of 100 for implementing material distribution, so that gradual change from one side to the other side in a continuous gradient manner is realized. The ceramic tile comprises the following components: zirconium dioxide Zr02, silicon dioxide SiO2, yttrium oxide Y203, calcium zirconate eutectic CaZrO3, barium zirconate eutectic BaZrO3, magnesium-zirconium eutectic MgZrO3, corundum alpha-Al2O3, alumina powder alpha-Al2O3, alumina fiber whisker alpha-Al2O3, silicon carbide SiC, silicon nitride Si3N4 and magnesium oxide MgO. Thepreparation method is convenient to operate and comprises the following steps of 1, preparing raw material components, 2, carrying out process treatment on each layer of components, and d, sintering amolded product.

Description

technical field [0001] The invention relates to a ceramic brick with gradient gradient composite technology 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, semiconductors, and optics. Such as infrared window materials, substrate substrates in the field of microelectronics, laser substrates, optical components, mobile phone screen glass and other uses. At present, the glass industrial pool kilns used in glass manufacturing are used in China and the global glass industry. All domestic and international glass kilns use fused zirconia corundum bricks, also known as AZS. The English abbreviation of fused zirconia corundum bricks is AZS, for example No. 33 fused-cast zirconium corundum brick, abbreviated as AZS-33#, No. 36 fused-cast zirconiu...

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.
