Our Advanced Ceramic Materials
Explore our range of high-performance ceramic materials, each engineered for strength, durability, and superior performance in demanding environments. From alumina and zirconia to silicon carbide and silicon nitride, our materials are designed to meet the technical requirements of industries worldwide.
Alumina Ceramic
Alumina ceramics are the most widely used fine ceramic materials, known for their outstanding properties such as high electrical insulation, excellent mechanical strength, and strong resistance to wear and chemicals. At our company, we specialize in advanced ceramics, including Zirconia, high-purity Alumina (95%–99.99%), Silicon Nitride, Silicon Carbide, and ZTA/ATZ, which are ideal for high-performance and demanding applications.
Alumina Ceramic
-
YSZ ceramics are widely used to handle corrosive chemicals and molten metal. It also provide low contamination due to the wear resistance and corrosion resistance.
-
Applications of Yttria Stabilized Zirconia (YSZ) parts
-
Used for grinding ceramics materials, magnetic materials and organic samples
-
Bearing and other wear resistance mechanical parts
-
Special pump parts
Magnesium/Ceriu Stabilized Zirconia
-

Zirconia Toughened Alumina
-
ZTA is the result of stress-induced phase transformation toughening and is achieved by uniformly mixing fine zirconia particles throughout the alumina. Typically, we offer ZTA contains 6% volume of zirconia in alumina. Also the ZrO2 content is flexible depends on the demands of applications.
-
The most used toughening method for alumina ceramics is ZrO2 (VK-R30) toughening.
Silicon Nitride
-
Silicon nitride ceramics is superior to other materials due to its thermal shock resistance. It does not deteriorate at high temperatures, so it’s used for automotive engines and parts for gas turbines, including the turbocharger rotor.
-
silicon nitride bonded silicon carbide brick (silicon nitride bonded silicon carbide brick) refers to the use of SiC and Si as raw materials, by nitriding fired refractory products.
Silicon Carbide
-
The heat and properties of SiC make it a wide range of applications. The main driving force of interest for SiC in electronic applications is high power, high frequency and high temperature devices that are resistant to radiation damage.
-
It is the hardest of traditional abrasives, but has lower impact resistance than alumina and shows higher wear rates when used to grind steel.

How to Choose Ceramic Material
Choosing the right ceramic material depends on the mechanical, thermal, and electrical demands of your application. Explore the key properties below to compare performance and select the ideal material for your project.
Hardness Levels of Technical Ceramics
The hardness of ceramic materials varies: Zirconia (ZrO2) and Alumina (Al2O3) typically range from 8.8 to 9.0 on the Mohs scale, finding applications in dental implants and cutting tools due to their mechanical properties. Silicon Carbide (SiC) and Silicon Nitride (Si3N4) both exhibit a hardness of 9.0 on the Mohs scale, making them suitable for abrasive materials, refractories, and high-wear applications such as bearings and turbine components. These ceramics play vital roles across industries, offering excellent hardness properties to enhance performance and durability.
