Specification of Large Size High Hardness Aluminium Oxide Al2O3 Refractory Ceramic Crucible Large Capacity Alumina Ceramic Cylinder

This crucible handles high heat. It is made from aluminium oxide, known as alumina or Al2O3. The material is ceramic and designed for tough jobs. It is very hard. This hardness helps it resist wear and scratches. The crucible comes in a large size. Its shape is a cylinder. This design gives it a big holding capacity. You can put a lot of material inside.

The alumina content is high. This purity level is usually over 99%. High purity alumina gives excellent performance. It withstands very high temperatures. The maximum usable temperature is often above 1700°C. The crucible also handles sudden temperature changes well. This is called thermal shock resistance. It means the crucible won’t crack easily when heated or cooled fast.

These crucibles are built strong. They are dense and durable. You can use them many times. They resist attack from chemicals. Many acids and bases will not harm them. This makes them safe for labs and factories. Common uses include melting metals. They are good for heating alloys. You can use them for chemical analysis. They work well for processing minerals. They are also used in research work.

The cylinder shape is practical. It allows efficient heating. Heat spreads evenly inside. The large size fits bigger batches. You save time processing more material. Dimensions vary by model. Typical heights range from 100mm to 300mm or more. Diameters often range from 80mm to 200mm. Wall thickness is substantial. This adds strength for heavy loads. Tolerances are controlled for precision.

Applications of Large Size High Hardness Aluminium Oxide Al2O3 Refractory Ceramic Crucible Large Capacity Alumina Ceramic Cylinder

Large size high hardness aluminium oxide Al2O3 refractory ceramic crucibles are essential tools. They handle demanding high-temperature jobs. These crucibles are made from pure alumina ceramic. This material gives them exceptional properties. Alumina ceramic withstands incredibly high temperatures. It doesn’t melt or deform easily. This makes the crucibles perfect for melting metals. Precious metals like gold and silver need such crucibles. Base metals like copper and brass also require them. Industrial foundries rely on these crucibles daily.

The high hardness of alumina is another key feature. This hardness means the crucibles resist wear and abrasion. They last longer under tough conditions. Chemical stability is equally important. Alumina ceramic resists attack from many chemicals. Acids and bases often don’t affect it. This inertness is vital in chemical labs. Researchers use these crucibles for reactions and sample preparation. They trust the material won’t interfere.

Large capacity is a big advantage. These alumina ceramic cylinders hold significant amounts of material. This boosts efficiency. Users melt larger batches at once. They process more samples per run. This saves time and energy. The big size suits industrial production well. It also helps in large-scale research projects.

These crucibles are indispensable in metal casting. Jewelers melt precious metals in them daily. Foundries pour molten alloys from them constantly. Chemical engineers use them for high-temperature reactions regularly. Material scientists test new compounds inside them often. The large alumina cylinder provides reliable performance consistently. It handles intense heat and harsh chemicals confidently.
