We know that zirconia has a unique phase transition process, so we can achieve better product quality by adding stabilizers. Among them, the flexural strength of yttrium-stabilized zirconia materials is the best. Below is the introduction of yttrium oxide Stabilize zirconia.
The chemical formula of yttrium oxide powder is Y2O3. The surface is white and slightly yellowish powder. This substance is insoluble in water and alkali, but soluble in acid. Yttrium oxide is used as a stabilizer, this material is mainly a tetragonal structure. It is mainly used for manufacturing microwave magnetic materials and important materials for military industry (single crystal; yttrium iron garnet, yttrium aluminum garnet and other composite oxides), as well as optical glass, ceramic material additives, high-brightness fluorescent for large-screen TV Powder and other picture tube coatings, etc.
Among all zirconia materials, yttria stabilized zirconia has the highest bending strength, especially when sintered and pressed. Yttrium-stabilized zirconia has fine grains and is suitable for cutting tools due to its high abrasion resistance. It is used to cut a very sharp corner.
Yttrium-stabilized zirconia can be used to make crucibles for vacuum induction melting, high-purity zirconium sizing nozzles for steel making, or zirconium composite long nozzle bricks, etc., to make linings that use ultrahigh temperatures above 1800℃and linings for gas reaction furnaces With bricks.
Yttrium-stabilized zirconia products can be made into ultra-high temperature electric furnace heating elements, high temperature furnace tubes, wire drawing dies, etc. of high temperature furnaces due to their semiconductor properties. It can also be made into high-temperature solution for continuous temperature measurement of zirconia components and zirconia components of various oxygen analyzers.
Fused zirconia sand can be used as aggregate of zirconium indefinite materials, titanium alloy casting sand and plasma spraying materials. With the development of science and technology, the use of stabilized zirconia is constantly expanding to different fields.
The excellent grains of yttrium-stabilized zirconia make the produced ceramics densely dense without many pores, and have excellent mechanical strength, corrosion resistance, impact toughness, thermal shock resistance and extremely low thermal conductivity.
Due to these characteristics, yttrium stabilized zirconia is mainly used in wear parts, cutting tools and thermal barrier coatings.
