Alumina ceramics have long been known for their remarkable properties, such as high hardness, excellent thermal stability, and resistance to wear and corrosion. Among the various alumina ceramic products, the Industrial Alumina Ceramic 2-Hole Tube stands out as a critical component in many industrial applications. These tubes are widely used in high-temperature environments, particularly for housing thermocouples and other electrical instrumentation. Their unique properties make them ideal for demanding tasks in industries such as metallurgy, aerospace, and energy production.

Our Alumina Ceramic 2-Hole Tubes stand out for their exceptional mechanical strength, ensuring longevity and resistance to external forces. Whether in high-impact environments or extreme conditions, these tubes remain robust and steadfast, guaranteeing the utmost safety for your metal wires.

The development and production of Al2O3 porcelain originated in Germany. Since then, major American companies have successively developed various Al2O3 ceramics. In the field of research, they consider ceramic and metallization technologies together, so that the two can be better matched and adapted.

Alumina ceramic tubes have a wide range of applications, involving high temperature testing and analysis equipment in various industries, such as coal testing and analysis equipment, metallurgical powder testing and analysis equipment, chemical and glass industry testing and analysis equipment, etc.

Where alumina ceramics are applied I. Iron and steel plant: 1. Lining of cylinder mixer of sintering machine 2, drum package ceramic rubber 3. Fan impeller 4, disc feeder, dry trough 5, coke hopper, converter bin, coke tank weighing hopper, cyclone dust collector

Share an unexpected surprise in the new year. My consulting client at the end of last year sent an inquiry asking for a simple size price. We will make a complete quotation for the customer.

Aluminium Oxide is a raw material used in the production of advanced ceramics. In the process of oxidization, oxygen molecules form a powerful bond with the aluminium, making aluminium oxide the hardest of all oxides.

After the powder is formed, a biscuit with good shape is obtained, and then the biscuit is heated at a certain temperature. The biscuit undergoes volume shrinkage and finally becomes a compact sintered body. This process is called sintering. The driving force of alumina ceramic green body sintering is mainly the change of powder surface energy, that is, the surface energy of powder decreases, the surface area decreases, and the ceramic densifies. In the process of ceramic sintering densification, material transfer can be carried out through solid phase diffusion, including surface diffusion, grain boundary diffusion, lattice diffusion, etc. Normal pressure sintering is generally used in industry.
