Specifications of Industrial 99 Alumina Ceramic Spacer For Graphite Boat

Industrial 99 alumina ceramic spacers are important components for graphite boats utilized in high-temperature processes. These spacers maintain things different inside the watercraft. This prevents sticking and guarantees even heating or finish. They are made from 99% pure aluminum oxide ceramic. This product is exceptionally tough and trustworthy.

These spacers manage severe heat extremely well. They work flawlessly in environments up to 1700 ° C. They stand up to thermal shock successfully. Sudden temperature modifications will not fracture them easily. Their chemical resistance is likewise exceptional. They withstand extreme chemicals and corrosive atmospheres without breaking down. This makes them ideal for demanding heater applications.

Dimensional security is a vital feature. The spacers keep their precise sizes and shape even under intense warmth. This accuracy is important for constant process results. Their surface area is really smooth. This decreases call factors with wafers or other fragile items. Scrapes and contamination risks are minimized.

The high pureness of the alumina product is essential. It avoids undesirable contamination of sensitive products during processing. These spacers are basically inert. They will not react with many process gases or materials. This pureness ensures item high quality.

Industrial 99 alumina spacers are understood for their long life span. They sustain duplicated thermal biking without failing. This longevity translates to reduce substitute expenses and much less downtime. They are the workhorse element for semiconductor production, solar battery production, and other sophisticated heat treatments. Their performance directly impacts process return and performance. Selecting the right spacer matters for optimum results.

Applications of Industrial 99 Alumina Ceramic Spacer For Graphite Boat

Industrial 99 alumina ceramic spacers are essential components utilized inside graphite boats. Graphite watercrafts lug breakable items like silicon wafers during high-temperature processes. These procedures take place in heaters. The heat is severe. Graphite watercrafts can soften or warp under this intense warm and heavy tons. Alumina spacers stop this. They provide strong inner support.

The spacers keep the boat’s form stable. This security is essential. It stops the boat from flexing or fracturing. A broken watercraft ruins the product within. Alumina spacers conserve cash. They make graphite boats last a lot longer. You don’t require to change boats so frequently.

Pureness matters. Our spacers are 99% alumina. This high purity is important. It indicates the spacers launch nearly no contaminants. Tidy handling is vital for things like semiconductors. Contamination ruins batches. Alumina spacers safeguard item top quality.

Alumina deals with extreme warm quite possibly. It doesn’t thaw or break down quickly. Spacers maintain strength even above 1500 ° C. Graphite watercrafts need this support. Alumina likewise withstands thermal shock. Fast temperature level modifications will not split it. This dependability is essential for heater biking.

Alumina does not broaden much with heat. Its expansion rate is reduced. This matches graphite sensibly well. Various expansion rates cause tension. Tension brings about splits. Matching rates assist both parts last longer. Alumina is also really tough. It stands up to wear from packing and unloading. It takes on chemical direct exposure in the furnace environment.

These spacers are made use of extensively. They are common in semiconductor crystal growth. They are used in LED manufacturing and solar cell production. Any kind of procedure making use of graphite boats in high warm advantages. The spacers protect against boat deformation. They lower contamination dangers. They prolong boat life significantly. They make sure constant, reliable furnace operation. This leads to much better returns and reduced prices.

5 FAQs of Industrial 99 Alumina Ceramic Spacer For Graphite Boat

What is this alumina ceramic spacer?
This spacer separates silicon wafers inside graphite boats during high-temperature processing. It prevents wafers from touching each other or the boat. This keeps wafers safe and clean during steps like diffusion or annealing. It’s made from 99% pure alumina ceramic.

Why use alumina ceramic?
Alumina ceramic handles extreme heat very well. It resists chemical corrosion from harsh furnace gases. It won’t contaminate sensitive silicon wafers. It stays strong and doesn’t warp even after many uses. This material is reliable for tough semiconductor work.

How hot can it go?
These spacers work fine up to 1600°C (2912°F). They handle standard semiconductor furnace temperatures easily. They won’t melt or degrade at these heats. They also handle fast heating and cooling cycles well. They won’t crack from sudden heat changes.

What sizes are available?
Many sizes exist to fit different graphite boats and wafer sizes. Common ones work for 150mm, 200mm, and 300mm wafers. Custom sizes are possible too. Check the specifications for exact dimensions before ordering. Match it to your boat design.

How should I handle it?
Handle spacers carefully. Avoid dropping them or hitting them hard. Alumina is strong but can chip with rough treatment. Keep them clean before use. Use tongs or gloves when placing them in the furnace. Inspect them regularly for cracks or chips. Replace damaged spacers immediately.
