Product Description Refractory Zirconia Hollow Ball Brick for High Temperature FurnaceProduct DescriptionZirconia Bubble Bricks DescriptionZirconia bubble bricks are thermal insulation and refractory products made mainly from zirconia hollow spheres. The main crystalline phase of this brick is cubic zirconia (approximately 70% to 80% of the mineral phase composition), with a fire resistance greater than 2400 oC. The production method of zirconia hollow ball bricks is the same as that of alumina hollow balls, except that its melting temperature is higher, reaching above 2700 oC. CaO is widely used as a stabilizer in China.Zirconia Bubble Bricks FeaturesZirconia bubble brick is a high-performance insulation material with excellent insulation effect, and has the following main advantages:1. Low thermal conductivity: Zirconia hollow ball bricks are filled with a large number of air micropores or hollow balls inside, and the bricks themselves have the characteristics of high-temperature ceramics, making their thermal conductivity very low, which can effectively reduce heat transfer. This low thermal conductivity can greatly improve the insulation effect and ensure stable temperature around the heat source.2. Temperature deformation resistance: Zirconia hollow ball bricks have excellent high-temperature stability and can withstand extremely high temperatures, making them less prone to deformation or melting. Therefore, zirconia hollow ball bricks can maintain good shape and performance in high-temperature environments, without causing a decrease in insulation effect due to long-term use.3. Good chemical stability: Zirconia hollow ball bricks have excellent chemical stability and can maintain good performance in corrosive environments such as acid and alkali. Therefore, the insulation effect of this material will not decrease due to the action of chemicals.Product ParametersLtemAlumina bubble brickZirconia Bubble Bricks 85 brick90 brick99 brick98 brickMaximum use temperature oC1680170018002200Al2O3 %≥85≥90≥99-ZrO2 %---≥99SiO2 %≤13≤8≤0.2≤0.2Fe2O3 %≤0.2≤0.2≤0.2≤0.2Bulk Density (g/cm3)1.4-1.71.4-1.71.4-1.7≤3Cold compression Strength (Mpa)≥12≥10≥9≥8Refractoriness undr load oC≥1650≥1700≥1700≥1700Zirconia Bubble Bricks ApplicationZirconia bubble bricks are excellent thermal insulation and refractory products with a maximum safe operating temperature of 2200 oC. They are used as high-temperature lining materials in direct contact with flames in thermal equipment in industries such as metallurgy, petrochemical, and electronics, and have good performance. Usually used as insulation materials for furnace covers and other parts in ultra-high temperature equipment, such as medium frequency high-temperature furnaces, carbon black reaction furnaces, tungsten rod furnaces, molybdenum furnaces, etc.Packaging & ShippingStandard international export packingPacking requirements: can be packed according to customer requirementsPackage Type: packed on wooden pallets, with water-proof cover, and tightened with plastic/steel bandagesCompany ProfileZhengzhou Rongsheng Refractory Material Co., Ltd.Established in the early 90s of twenty century, with continuous innovation and development, now we are a comprehensive enterprise in refractory material industry, covering metallurgy, building materials, electric power, chemical industry,etc.Our main products: refractory material for industrial furnaces, such as high-alumina brick, clay brick, silicon brick, high-strength diatomite brick, light weight insulation brick, low iron mullite brick, etc.; anti-stripping alumina brick, alkali proof brick, phosphate brick for cement industry; For the industrial furnace and power boiler, we can provide abrasive brick, corundum brick, mullite brick, wear resistant castable, corundum castable, high strength low cement castable, impervious material, plastic refractory, graphite electrode etc.Our main export markets : North America, Western Europe, Eastern Europe, South America, Southeast Asia, Eastern Asia, Mid East, Oceania, AfricaWe have own workshop , advanced production line , experienced workman and stricted check out flow .We always pursue the objective of "Honesty, Courtesy, Innovation, Dedication", the cornerstone of "Super Quality & Competitive Price", and the strategic goal of building Rongsheng brand, to serve the clients in a timely and effective way.Send us inquiry to got more !!!
