Specifications of C795 C799 High Purity Refractory Corundum Al2O3 Alumina Ceramic Crucible Sagger Tray Boats

The C795 and C799 alumina ceramic crucibles, saggers, trays, and watercrafts are made from high pureness corundum. This product mores than 99% pure light weight aluminum oxide (Al2O3). The high purity offers excellent performance under tough conditions. These components manage extremely high temperatures quickly. They function well constantly as much as 1750 ° C. Short term usage can get to 1800 ° C. This makes them excellent for demanding warm procedures.

They possess high bulk thickness. This density is around 3.7 g/cm FIVE. The thick structure resists chemical attack well. Solid acids and bases trigger minimal damage. Molten metals and lots of slags do not pass through the surface. This makes sure long service life and product pureness. Thermal shock resistance is an additional vital attribute. The material handles quick temperature changes. Sudden home heating or cooling down causes less breaking. This reliability decreases unforeseen failures.

These elements come in basic sizes and shapes. Crucibles hold little amounts of product for melting or analysis. Saggers safeguard products inside kilns during shooting. Trays sustain components throughout heat therapy. Watercrafts lug products via heater tubes. Customized sizes and styles are likewise feasible. Makers can satisfy certain application demands. The smooth surface area coating prevents contamination. Samples remain tidy throughout processing.

Typical uses include powder metallurgy and ceramic sintering. They are important in crystal growth and semiconductor handling. Research laboratory analysis and stimulant study rely on them. Handling calls for like avoid damaging. Prevent sharp effect on the tough yet breakable material. Proper cleansing after use maintains efficiency. Comply with the manufacturer’s guidelines for best results. These alumina ceramics offer trustworthy thermal and chemical stability. They are a solid choice for essential high-temperature applications.

Applications of C795 C799 High Purity Refractory Corundum Al2O3 Alumina Ceramic Crucible Sagger Tray Boats

C795 and C799 are high pureness alumina porcelains. They are made mostly from aluminum oxide (Al2O3). This material is exceptionally pure. This pureness matters a lot. It suggests the porcelains will not include undesirable stuff to whatever you are refining inside them. These ceramics are difficult. They deal with very high warmth well. You can use them safely at temperature levels over 1700 ° C. They stand up to sudden temperature level adjustments. This is thermal shock resistance. It stops them cracking when home heating or cooling quick. They are also really tough. They wear down gradually. This provides a long working life. They resist chemical attack also. Acids and bases do not easily damage them.

These buildings make C795 and C799 ideal for many requiring jobs. Crucibles are a significant usage. You melt metals or alloys in them. They help rare-earth elements like gold and platinum. They work for reactive metals also. These porcelains don’t pollute the melt. Saggers and trays (watercrafts) are an additional large usage. You discharge ceramic parts or electronic elements inside them. The high pureness stops contamination. The warm resistance protects the parts during firing. Semiconductor processing requires this pureness. Silicon wafers obtain refined in these alumina watercrafts. No impurities can ruin the wafers.

Chemical processing uses these ceramics. They hold destructive chemicals at high temperatures. Labs count on them. Crucibles and watercrafts take care of aggressive samples throughout evaluation. They are important for precise outcomes. Powder metallurgy utilizes them. You sinter metal powders inside alumina saggers. The high temperature ability is vital. Glass production utilizes them in some cases. You process special glasses needing clean atmospheres. These ceramics supply that. Their toughness and use resistance indicate they last. You save money by not changing them commonly. They are dependable workhorses. You trust them for important high-temperature procedures.

5 FAQs of C795 C799 High Purity Refractory Corundum Al2O3 Alumina Ceramic Crucible Sagger Tray Boats

Here are 5 key questions about our C795 C799 High Purity Corundum Alumina Ceramic Crucible Sagger Trays:

What temperature can these crucibles handle? They withstand very high heat. They are rated for continuous use up to 1800°C (3272°F). Short-term peaks can go even higher. This makes them suitable for intense processes.

Do they handle sudden temperature changes well? Yes, they resist thermal shock effectively. You can heat them rapidly or cool them down quickly. This resistance prevents cracking during fast temperature shifts common in labs and industry.

What chemicals are they resistant to? These crucibles resist attack from many substances. They handle strong acids and strong alkalis well. They also resist molten salts and many metal oxides. They are not good for hydrofluoric acid or strong phosphoric acid.

How should we clean them? Cleaning is straightforward. Use common acids like hydrochloric or nitric acid solutions. Avoid abrasive cleaners that might scratch the surface. Rinse them thoroughly with clean water after washing. Let them dry completely before reuse.

How long do these crucibles typically last? Lifespan depends on usage conditions. This includes the exact temperature, the chemicals involved, and how often thermal cycling happens. With proper care, they last significantly longer than lower purity alternatives. They offer good value over time.
