      zirconia product

              zirconia product It is a heat-insulating refractory product made of zirconia hollow spheres. The main crystalline phase of this kind of brick is cubic zirconia (about 70% to 80% of the mineral composition). The refractoriness is greater than 2400 degrees, the apparent porosity is 55% to 60%, the bulk density is 2.5 to 3.0g/cm3, the compressive strength is not less than 4.9MPa, and the thermal conductivity is 0.23 to 0.35w/ (M. K). The production method of zirconia hollow brick is the same as the production method of alumina hollow spheres, but its melting temperature is even higher than 2700 CaO.

          Meticulous, practice the core values; do not rush, carving the quality of Jinma products! Hello, Dear customer, thank you for clicking into the official business website of Gongyi Jinma burden Co., Ltd. The quality of zirconia hollow brick is stable. It reflects the reassuring Chinese manufacture. It is the Golden Horse burden that has never stopped pursuing for many years. If you want to know more about the actual application of zirconia hollow brick products, please visit the following zirconia hollow brick product information or call the Jinma charging material [zirconia hollow brick] technical advisory telephone: [13803857549 (Cai Jingli)] Learn more first-hand information!

            zirconia product yes Insulating refractory products made from zirconia hollow spheres. The main crystalline phase of this kind of brick is cubic zirconia (about 70% to 80% of the mineral composition). The refractoriness is greater than 2400 degrees, the apparent porosity is 55% to 60%, the bulk density is 2.5 to 3.0g/cm3, the compressive strength is not less than 4.9MPa, and the thermal conductivity is 0.23 to 0.35w/ (M. K). zirconia product The production method is the same as the production method of alumina hollow spheres, but its melting temperature is even higher than 2700 CaO.

      Zirconia hollow spheres are made entirely of zirconia hollow spheres. They have good high temperature strength and stable pore structure. They are used for insulating materials in furnace cover such as medium frequency high temperature furnace, carbon black reaction furnace, tungsten bar furnace, molybdenum furnace and so on. Zirconia hollow brick is an excellent insulating and refractory product. Its high safety temperature is 2200 degrees. It is used as a high temperature lining material for direct contact with flame in metallurgical, petrochemical and electronic industries.

            zirconia product The production method is the same as the production method of alumina hollow spheres, but its melting temperature is even higher than 2700 CaO. The bricks were made of zirconia hollow spheres (65% to 70%) and zirconium fine powders (30% to 35%) as raw materials, and boric acid aqueous solution as binding agents. After mixing evenly, the bricks were formed by pressure vibration molding machine. The bricks were dried and dried at 1700~1800 degrees Celsius.
      Zirconia hollow spheres used in raw materials are zirconia as raw materials, calcium oxide (or yttrium oxide and Magnesium Oxide) as stabilizers, evenly mixed, and melted by arc melting into compressed air. Zirconia fine powder is made of zirconia as raw material, calcium oxide (or yttrium oxide and Magnesium Oxide) as stabilizer, evenly mixed, fused into molten liquid, condensed and crushed and ground.
