Aluminum oxide ceramic solid rod, wear-resistant and high-temperature resistant industrial ceramic
product name:Alumina ceramic rod
1. Aluminum oxide ceramics have properties such as high temperature resistance, corrosion resistance, and high strength, so they are used as sliding nozzles for pouring steel, crucibles and vessels for smelting rare and precious metals, special alloys, high-purity metals, and glass wire drawing; Various high-temperature furnaces, such as refractory materials, ceramics, and the lining (walls and pipes) of ironmaking blast furnaces; Physicochemical vessels, spark plugs, heat-resistant and antioxidant coatings. Low silicon sintered corundum bricks with SiO2 less than 0.5% are specialized furnace linings for carbon black, boron chemical, fertilizer, synthetic ammonia reaction furnaces, and vaporization furnaces;
2. Aluminum oxide ceramics have the characteristics of high hardness, good wear resistance, and high strength. In chemical systems, they are used as components for various reactors, pipelines, and chemical pumps; Produce mechanical components and various molds, such as wire drawing dies, pencil lead extrusion dies, and nozzles; Used as cutting tools, abrasive tools, bulletproof materials, human joints, sealing grinding rings, etc;
3. Aluminum oxide ceramics also have high-temperature insulation properties, so they are used as wire sleeves and protective tubes for thermocouples. The insulation properties used in atomic reactors are still excellent, coupled with low losses and low dielectric constants. They are widely used in the electronic industry for solid integrated electric furnace substrate tube seats, shells, ceramic frames, thin windows, missile radar antenna protective covers, etc;
