Introduction to Alumina Ceramics

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 Ceramics

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.

Corrosion resistance: Alumina ceramics have good resistance to most acids and alkalis, making them widely used in the chemical industry.

Good electrical insulation: As an excellent electrical insulating material, alumina ceramics are widely used in electronic and electrical products.

High temperature stability: Ability to withstand extremely high temperatures without significant physical or chemical changes, which makes it an ideal choice for applications in high temperature environments.

Biocompatibility: In the medical field, certain grades of alumina ceramics are used to make medical devices such as artificial joints due to their good biocompatibility.

Specifications of 95% 99%al2o3 Alumina Ceramic Porcelain Clay Boat Crucible for Labory

Our alumina ceramic crucibles offer lab requirements. They can be found in 2 main purity levels: 95% Al2O3 and 99% Al2O3. These boat-shaped containers deal with heats well. They stand up to thermal shock. This implies they will not break quickly during rapid heating or cooling. Their high alumina content guarantees chemical stability. They withstand acids, antacid, and molten materials without reacting. This avoids example contamination during experiments.

The manufacturing procedure uses premium porcelain clay. This causes a smooth, non-porous surface. The surface is simple to clean after use. These crucibles are reusable. They last much longer than less costly choices. Their toughness decreases laboratory expenses gradually. They execute accurately in heaters, kilns, and ovens. Usual applications include sample calcination, sintering, and metal melting. They work for ash web content testing also.

We provide numerous dimensions to fit various tools. Requirement capabilities include 5ml, 10ml, 30ml, and 50ml. Larger custom-made sizes are offered. The 99% pureness variation deals with much more extreme problems. It fits innovative study requiring optimum temperature level resistance. The 95% purity type helps regular laboratory jobs. Both variations keep structural stability as much as 1700 ° C. Their uniform heating advertises exact examination outcomes. These crucibles fit the majority of tube heating systems and muffle heaters. Proper handling avoids accidental breakage. They ship with protective packaging.

Applications of 95% 99%al2o3 Alumina Ceramic Porcelain Clay Boat Crucible for Labory

Alumina ceramic crucibles are necessary devices in several research laboratories. These crucibles come in 2 purity qualities. You get 95% alumina or 99% alumina options. Both kinds supply exceptional performance under requiring problems. They are made from high-purity aluminum oxide ceramic. This product is frequently called porcelain clay. It provides the crucibles their vital residential or commercial properties.

Warm resistance is the major benefit. These crucibles handle extremely heats conveniently. They withstand constant consume to 1750 ° C. Short-term exposure to also greater warmth is possible. This makes them excellent for melting steels. They are excellent for calcining products. Expanding crystals typically calls for these crucibles. Shooting porcelains uses them also.

Chemical stability is an additional major advantage. Alumina ceramic resists strike from many chemicals. Acids usually do not influence it a lot. Bases generally create little damages. Molten salts connect minimally with it. This inertness secures your examples. It protects against contamination of your experiments. You obtain reliable outcomes.

Toughness is important for lab work. These crucibles are very hard. They withstand abrasion and scratching well. Thermal shock resistance is great. They cope with quick temperature level changes. This reduces breakage risks. It saves cash gradually. You replace crucibles much less commonly.

The boat shape prevails. This design functions well for numerous applications. It permits simple loading of examples. It gives a steady system inside furnaces. Different sizes are readily available. You find tiny ones for little samples. Larger dimensions handle larger batches. Select the dimension suitable your particular job.

5 FAQs of 95% 99%al2o3 Alumina Ceramic Porcelain Clay Boat Crucible for Labory

Here are 5 FAQs about the 95% 99% Alumina Ceramic Crucible:

What makes high purity alumina good for crucibles?
Alumina is very hard. Alumina is very heat resistant. Crucibles need these properties. High purity means 95% or 99% Al2O3. Less impurities exist. This makes the crucible stronger. This makes the crucible last longer under intense heat. It handles chemicals better too.

What’s the maximum temperature this crucible can take?
These crucibles handle very high heat. The maximum safe temperature is 1700°C. This is for short periods. Don’t exceed this limit. Exceeding 1700°C risks damage. The crucible might crack or break. Always check your furnace’s actual temperature.

Can I use this crucible with all chemicals?
No. These crucibles resist most acids and alkalis well. This is good for many lab melts. But they are not perfect. Avoid strong alkalis like molten sodium hydroxide. Avoid hydrofluoric acid completely. Hydrofluoric acid attacks alumina. It will ruin the crucible.

How do I clean the crucible after use?
Cleaning is important. Let the crucible cool completely first. Don’t put a hot crucible in water. Sudden cooling causes cracks. Once cool, wash it. Use water. Use a mild detergent if needed. A soft brush helps remove residue. Avoid harsh abrasives. Harsh abrasives scratch the surface. Scratches weaken the crucible.

Is the crucible fragile?
Yes. Alumina ceramic is hard. Alumina ceramic is also brittle. Handle it carefully. Avoid impacts. Avoid dropping it. Don’t subject it to rapid temperature changes. Heat it up slowly. Cool it down slowly. This prevents thermal shock cracks. Always place it securely in your furnace.
