95% 알루미나 세라믹스의 내열성
In fields such as industrial manufacturing, electronics and electronics, and aerospace, the stability and reliability of materials in high-temperature environments are key factors determining equipment performance and lifespan. Among numerous engineering materials, 95 알루미나 세라믹 stand out for their excellent heat resistance and have become one of the preferred materials for dealing with extreme thermal challenges.
What is 95 alumina ceramic?
95 alumina ceramic is an advanced industrial ceramic with alpha alumina (Al ₂ O3) as the main crystal phase, with an alumina content of up to 95%. The remaining 5% is usually composed of oxides such as silicon, magnesium, calcium, etc. These sintering aids play a crucial role in optimizing their microstructure and mechanical properties. It is precisely this unique composition and precise manufacturing process that endow it with unparalleled heat resistance.
Product advantage: Core characteristics behind heat resistance
The heat resistance of 95 alumina ceramics is not a single indicator, but is composed of a series of interrelated excellent properties:
- High melting point and excellent thermal stability: 95 alumina ceramics have a melting point of over 1700 ℃, and can maintain structural stability even in extreme high temperature environments of 1500 ℃ for a long time without softening or deformation. This ensures its long-term service life in high-temperature furnaces and other equipment.
- 낮은 열팽창 계수: The degree of expansion of the material when heated is very small, which means that when subjected to drastic temperature changes (thermal cycles), the thermal stress generated is small, thus possessing excellent thermal shock resistance and not easily cracking due to rapid cooling and heating.
- 열 전도성이 뛰어납니다: It has good thermal conductivity and can quickly transfer heat to avoid local overheating, which is crucial for electronic components and high-temperature fixtures with high heat dissipation requirements.
- Outstanding high-temperature insulation: Even at high temperatures, its electrical insulation performance hardly deteriorates, effectively preventing current breakdown and ensuring the safe operation of high-temperature electrical equipment.

Customer real case (anonymous processing)
Background of the case: A large domestic steel enterprise found that the traditional alloy furnace rollers in its annealing furnace are prone to creep and bending under long-term working temperatures above 1000 ℃, resulting in the deviation of the strip steel on the roller conveyor and surface scratches. This not only affects product quality, but also requires monthly shutdowns to replace the furnace rollers, causing huge losses.
Our solution: We have customized 95 alumina ceramic furnace rollers for it. This component utilizes the high-temperature structural stability and low creep of ceramics to maintain extremely high straightness under the same operating conditions.
Application effect: After using our 95 alumina ceramic furnace rollers, the average service life of the rollers has been increased by more than three times, and the problem of strip steel deviation has been fundamentally solved. The surface quality of the product has been significantly improved, while significantly reducing downtime and replacement costs, creating considerable economic benefits for customers.
