We just produced a 310 * 310 * 1.0mm of thermal conductivity aluminum nitride ceramic that can be used as a semiconductor 12-inch GaN-on-QST substrate.

GaN-on-QST，QST is the abbreviation of "Qromis substrate technology", which is a substrate for GaN epitaxy, with properties similar to GaN coefficient of thermal expansion.GaN-on-QST that the underlying substrate is aluminum nitride ceramic sheet .

Below is the contrast of GaN/Si and GaN/QST substrate ,QST substrate has more advantages，and the cost is lower than GaN/Si substrate.

In near future,GaN/QST with AlN ceramic underlying substrate will be a new wonderful application.

We just produced high thermal conductivity Aluminum Nitride Ceramic for the large-area cooler.

 The monolithic structue made of Aluminum Nitride(AlN) is airtight after firing, making it perfect for high external pressure applications.

The adavantages of AlN Ceramic for large-area liquid cooler are that the design of monolithic heat-sink provides excellent heat transfer from the ceramic to the cooling water and both cooling connections are on the same side which are inserted with two seal rings.

Therefore, our AlN Ceramic for large area liquid cooler is well suited for applications that require effective cooling of large areas.

We produce black color Alumina Ceramic Disc with high purity.

As a special ceramic packaging materials, black alumina ceramic's density is smaller than the general metal packaging material and better hermeticity than plastic packaging materials. In the requirements of electronic packaging with high reliability, hermeticity and heat shock performance, black alumina ceramic has advantages other kinds of packaging materials can not replace.

As semiconductor integrated circuits often have obvious photosensitivity, alumina used for digital tube liner is also required to be black to ensure that the digital display is clear, and the special ceramic material used for encapsulating the tube shell should be required to have light shielding. Therefore, the black color cermic meets the requirement of some electronic products to avoid light.

We produced Aluminum Nitride Ceramic Equipment Slotted Disc for semiconductor manufacturing.

The process of manufacturing semiconductors includes a harsh environment where plasma is generated. Therefore, the Aluminum Nitride(AlN) ceramic with excellent plasma resistance are more suitable for semiconductor manufacturing. What's more, in the fabrication of semiconductors, a combination of volatile precursor gases, plasma and high temperatures are used to lay high quality films onto the wafers. Deposition chambers and wafer handling tools require durable ceramic components to withstand these challenging environments, so the Aluminum Nitride Ceramic Slotted Disc is suitable for the semiconductor industry.

Oriented silicon steel, commonly referred to as CRGO (Cold-Rolled Grain-Oriented), is a highly specialized silicon steel material that holds a paramount position in the manufacturing of electrical equipment and transformers. This material, distinguished by its unique magnetic properties, serves as a cornerstone in the power industry and electrical manufacturing sectors.

CRGO silicon steel is composed primarily of silicon and iron, with silicon content typically ranging from 1.5% to 4.5%. Through a rigorous cold-rolling process, the magnetic domains within CRGO are meticulously aligned, resulting in exceptional magnetic conductivity along specific directions. This alignment is crucial as it enables CRGO to dramatically reduce iron losses and significantly enhance the efficiency of transformers, reactors, and other electrical devices.

The versatility of CRGO silicon steel spans across a wide range of applications. From large-scale power transformers that form the backbone of national grids to transformers embedded in small household appliances, CRGO contributes significantly to the stable operation and energy-saving capabilities of electrical systems. Moreover, its applications extend into high-voltage transmission equipment, power supply systems for urban rail transit, and renewable energy sectors such as wind and solar power generation.

CRGO silicon steel's unique characteristics, including low core loss and high permeability, make it indispensable in the power industry. As the global focus on energy conservation and emission reduction intensifies, the demand for CRGO silicon steel continues to grow. Its extensive applications not only improve the energy efficiency and stability of electrical equipment but also contribute to a more sustainable future.

In summary, CRGO silicon steel is a material with exceptional magnetic properties that plays a vital role in the electrical industry. Its diverse applications and significant contributions to energy efficiency and sustainability make it a cornerstone in the ongoing evolution of power systems worldwide.

In the realm of electrical engineering, silicon steel stands as a quiet but powerful innovator, driving advancements in energy efficiency. This unique alloy, which combines iron with a significant percentage of silicon, possesses magnetic properties that are tailored for optimal electrical performance. By minimizing hysteresis and eddy current losses, silicon steel helps reduce energy waste, making it a cornerstone for the development of high-efficiency transformers and other critical electrical components.

 

At the forefront of this technological evolution is CRGO (Cold Rolled Grain Oriented) steel. Through a meticulous process of rolling, annealing, and laser scribing, the grains within CRGO steel are precisely aligned to match the direction of the magnetic field. This alignment minimizes losses and maximizes efficiency, making CRGO the gold standard for transformers used in power grids and renewable energy systems.

Building on the success of CRGO, oriented silicon steel further refines the grain orientation process. By optimizing the silicon content and grain alignment, oriented silicon steel achieves even higher magnetic induction and lower losses, especially under high magnetic fields. This makes it an indispensable material for high-voltage transformers and large-scale power inverters, where precision and efficiency are paramount.

 

In summary, silicon steel, and its advanced forms CRGO and oriented silicon steel, are not just materials; they are the unsung heroes of energy efficiency. Their unique properties and processing techniques make them essential for the development of high-performance transformers and other electrical components, paving the way for a cleaner, more sustainable energy future.
