Specification of Polished Al2O3 Alumina Ceramic Plate

Refined Al2O3 alumina ceramic plates offer high efficiency. They are made from pure aluminum oxide. This product provides exceptional firmness. They are very immune to wear. This makes them last a long time.

These plates handle extreme warm well. They work great in temperature levels over 1500 ° C. Their thermal security is great. Abrupt temperature level changes generally do not split them. This is thermal shock resistance.

Electric insulation is one more essential function. Alumina is a solid insulator. It works well also at high voltages. This residential property is critical for electronics. It stops electric currents from leaking.

The chemical resistance goes over. Alumina plates resist numerous acids and antacids. They do not wear away easily. Severe chemicals seldom harm them. This suits them for tough settings.

Production involves pushing and sintering alumina powder. The outcome is a dense, solid ceramic body. After sintering, the plates get accuracy grinding. This guarantees precise density and flatness. After that comes the polishing step.

Polishing develops an extremely smooth surface area. The surface finish is usually gauged in Ra. Worths like Ra 0.05 μm or reduced are possible. This ultra-smooth finish minimizes friction. It likewise prevents fragment generation.

These plates are offered in lots of dimensions. Usual densities range from thin sheets to thick blocks. Custom forms and openings are possible. Machining after sintering accomplishes this. Tight resistances are conventional.

The sleek surface area is very easy to clean. It stands up to sticking. This is important for semiconductor tools. It helps in food processing equipment too. Numerous sectors make use of these plates.

Applications include precision equipment components. They function as wear-resistant liners. They are superb electrical insulators. High-temperature furnace parts utilize them. Important surface areas in clinical tools rely upon them. Their level of smoothness stops contamination.

Applications of Polished Al2O3 Alumina Ceramic Plate

Polished Al2O3 alumina ceramic plates are extremely difficult and wear-resistant. They handle severe warm well. This makes them excellent for tough jobs. Lots of industries require these buildings.

The semiconductor sector utilizes them heavily. They act as wafer chucks. They hold silicon wafers throughout processing. The smooth surface area prevents scrapes. It keeps wafers perfectly flat. They are additionally great insulators. This stops electrical troubles throughout chip making.

Medical tools depends on these plates also. Their smoothness is crucial. It stops germs from sticking. This makes cleansing simple. They are biocompatible. This means they are risk-free inside the body. They are made use of in joint replacements. They are utilized in dental implants. They are used in medical tools.

Accuracy equipment needs level, steady surfaces. Sleek alumina plates give this. They are utilized as reference surfaces. They are utilized as gliding surfaces. They are utilized as wear plates. They resist abrasion far better than steel. This maintains machines running accurately longer. They handle heats without contorting.

Laboratories utilize them for testing. They supply a hard, inert surface area. Chemical spills will not damage them. They are steady under warm. They are secure under stress. They function well for sample prep work. They function well for product evaluation.

The surface area coating matters a great deal. A high polish lessens rubbing. It minimizes fragment generation. It protects against product sticking. This is important for tidy processes. This is important for high-precision work. Refined alumina plates address several engineering problems. They use dependability where various other products fall short.

5 FAQs of Polished Al2O3 Alumina Ceramic Plate

What is polished Al2O3 alumina ceramic plate?
This plate is aluminum oxide ceramic. It gets a special finish. This process makes the surface very smooth. It also makes the surface shiny. The base material is very hard. It resists wear well. It handles high heat. It is electrically insulating. The polishing step improves the surface finish significantly.

Why polish the alumina ceramic plate?
Polishing creates a smooth surface. A smooth surface reduces friction. Low friction is good for sliding parts. Polishing makes the plate easier to clean. Dirt and liquids don’t stick as easily. The polished look is often preferred. It gives a more professional appearance. Polishing can also seal tiny pores on the surface. This makes the plate less likely to absorb contaminants.

How hot can this plate get?
Polished alumina plates handle very high temperatures. They work fine up to about 1600°C (2912°F). Their strength stays good even when hot. Most metals melt at much lower temperatures. This makes them ideal for furnace parts. They are good for high-heat fixtures. The polish itself does not reduce the temperature rating. The base material determines the heat resistance.

How do I clean this plate?
Cleaning is simple. Use mild soap. Use warm water. Wipe the surface gently. Avoid harsh chemicals. Avoid abrasive cleaners. These cleaners can scratch the polished finish. The plate resists most chemicals well. Strong acids or strong alkalis might damage it over time. Rinse the plate thoroughly after cleaning. Dry it with a soft cloth.

Is the polished plate fragile?
Alumina ceramic is very hard. It is also brittle. Brittle means it can crack if hit hard. It can chip if dropped. Handle it carefully. Avoid sharp impacts. Do not bend it. It will not flex like metal. Protect the edges. The edges are the most vulnerable. The polishing doesn’t make it weaker. It doesn’t make it stronger either. Use it where high impact force isn’t expected.
