Introduction to Alumina Ceramic Substrate Insulation Aluminum Oxide Al2O3 Plate

Alumina ceramics are known for their high hardness, wear resistance, corrosion resistance, good electrical insulation and high temperature stability. According to the different alumina content, it can be divided into different grades, such as 95 porcelain, 99 porcelain, etc., among which 99 porcelain refers to ceramic materials with an alumina content of 99%. As the alumina content increases, its mechanical strength and electrical insulation properties will also increase accordingly.

Characteristics of Alumina Ceramic Substrate Insulation Aluminum Oxide Al2O3 Plate

High Hardness: Alumina ceramics have extremely high hardness, which makes it very wear-resistant and suitable for manufacturing abrasive tools and parts that require wear resistance.

Wear resistance: Due to its high hardness, alumina ceramics show excellent wear resistance and are suitable for manufacturing parts for long-term use.

Specifications of Alumina Ceramic Substrate Insulation Aluminum Oxide Al2O3 Plate

Alumina ceramic substrate provides top electrical insulation. This material is aluminum oxide, Al2O3. It works well in tough conditions. People use it in electronics, heaters, and machinery parts. It stops electricity flow very effectively. This makes circuits safe and reliable.

High purity is a key feature. Common levels are 96%, 99%, and 99.5% Al2O3. Higher purity usually means better performance. It handles high heat very well. The material withstands temperatures over 1500°C. This is important for furnaces or power devices.

Heat moves through it efficiently. Good thermal conductivity prevents hot spots. This protects sensitive parts nearby. It also resists sudden temperature changes well. This thermal shock resistance stops cracking. Parts last longer because of this.

The material is very hard. It scores high on the Mohs hardness scale. This hardness fights wear and scratches. It keeps surfaces smooth over time. Surface finish is critical. Ra values are precise, often under 0.8 microns. This smoothness is vital for thin films or circuits.

It blocks electricity strongly. The dielectric strength is high, measured in kV/mm. This prevents electrical shorts. The dielectric constant stays stable across frequencies. This stability is necessary for good signal quality.

The plate is strong mechanically. It resists bending forces well. Flexural strength is measured in MPa. This strength helps the plate survive handling and stress. It doesn’t expand much with heat. Low thermal expansion keeps dimensions stable. This avoids warping or connection problems.

Chemical resistance is another benefit. It stands up to acids and bases. Harsh chemicals don’t damage it easily. This is useful in chemical plants or labs. Machining precision matters. Tolerances are tight, often within ±0.1mm. This ensures parts fit perfectly every time.

Applications of Alumina Ceramic Substrate Insulation Aluminum Oxide Al2O3 Plate

Alumina ceramic substrate insulation offers reliable performance. This aluminum oxide Al2O3 plate handles tough conditions well. It works great for electrical insulation. Heat moves through it efficiently. This keeps electronic parts cooler. It stops parts from getting too hot. Many electronic devices need this feature. Circuit boards use these substrates often. Power modules rely on them too. LED lighting benefits from their heat spreading ability. Semiconductor equipment uses them widely.

The material withstands high temperatures easily. It remains stable under heat stress. Components stay safe and perform longer. This thermal stability is important. Industrial heaters use alumina plates. Sensors need stable platforms. Alumina provides that stable base. Furnace linings use it too. It resists chemical attack effectively. Harsh environments don’t damage it. Chemical processing equipment uses it. Lab apparatus finds it useful. The surface is very smooth. This allows precise printing. Thick film circuits need smooth surfaces. Thin film circuits do too. Alumina plates deliver that precision.

Mechanical strength is another key point. The material is quite hard. It resists wear over time. Bearings and seals use it. Cutting tools incorporate alumina. It doesn’t change shape easily. Temperature shifts don’t warp it. Precision parts stay accurate. The electrical insulation is top-notch. High voltages don’t pass through. This prevents short circuits. Power electronics demand this safety. Alumina substrates are non-reactive. They don’t contaminate processes. Vacuum systems use them safely. Medical devices often include them. Laser technology employs alumina plates. They manage heat in laser systems. Microwave tubes use them for insulation. Automotive electronics need their durability. Engine control units use them. Alumina handles engine heat and vibration.

5 FAQs of Alumina Ceramic Substrate Insulation Aluminum Oxide Al2O3 Plate

What’s alumina ceramic substrate?
It’s a plate made from aluminum oxide (Al2O3). This material is very hard. It resists high heat well. It also stops electricity from flowing. People use it in electronics and machines.

How hot can it get?
Alumina plates handle very high heat. Standard grades work fine at 1500°C or more. Exact limits depend on the purity level. Higher purity means better heat resistance. It doesn’t melt easily.

Why pick this over metal?
It doesn’t conduct electricity. Metal does. This insulation is vital for circuits. It handles heat much better than most metals. It resists chemical corrosion too. It doesn’t wear down quickly. This makes parts last longer.

Can you put metal on it?
Yes. You can add metal layers to its surface. This is common. Methods like screen printing or sputtering work well. The metal sticks to the ceramic. This creates circuits. The ceramic base insulates the metal traces.

Is it easy to break?
It is hard but brittle. Like glass, it can crack if hit hard. Handle it carefully. Avoid sharp knocks or drops. Cutting or drilling needs special tools. Diamond tools work best. Don’t apply sudden force.
