Applications of Ceramic 99% Alumina Ceramic Graphite Boat Rod Spacer Cushioning Spacer

99% alumina ceramic deals exceptional homes for demanding commercial uses. This material withstands severe warm, resists chemical attack, and offers outstanding electrical insulation. Its solidity and dimensional stability are key advantages. These traits make it ideal for specialized parts like graphite boat rod spacers and supporting spacers in high-temperature setups.

Graphite boats hold silicon wafers or various other products during processing. Extreme heat is common. Graphite expands substantially when warmed. Alumina ceramic spacers keep exact separation between graphite rods inside the watercraft. They prevent the poles from touching or warping under warm. This maintains the wafer settings secure and stops boat failing. The alumina does not soften or react with the graphite or procedure gases.

Rod spacers are simple forms like tubes or blocks. They fit in between graphite poles. Their job is keeping exact spaces. This ensures regular warmth transfer and shields the rods. Precise dimensions are critical for correct heater operation. Alumina ceramic supplies this precision reliably over many cycles.

Padding spacers soak up shock and resonance. They safeguard fragile products inside heater watercrafts during handling and heating. Alumina’s toughness and thermal shock resistance are important below. These spacers cushion wafers or delicate components. They prevent chips, fractures, or motion that damages the product. Alumina handles the fast temperature changes without breaking.

People utilize these alumina elements mostly in semiconductor manufacturing. They are additionally located in LED manufacturing, solar battery processing, and sintering heaters. The 99% pureness degree reduces contamination risks. This is essential for state-of-the-art applications. Alumina ceramic spacers expand graphite watercraft life. They improve procedure yield and reduce costly downtime. Their performance in extreme conditions is unrivaled by the majority of other products.

5 FAQs of Ceramic 99% Alumina Ceramic Graphite Boat Rod Spacer Cushioning Spacer

Ceramic 99% Alumina Spacer FAQs

What is this ceramic spacer made of?
This spacer is made from 99% alumina ceramic. Alumina ceramic is a very hard, dense material. It is mostly aluminum oxide. This makes it very resistant to heat and wear. It is not like regular pottery clay. It is an advanced technical ceramic.

How hot can it get?
This alumina spacer handles extremely high temperatures well. It works reliably up to 1600°C (2912°F). It resists sudden temperature changes. This is important for furnace use. It keeps its shape and strength under intense heat. Ordinary materials would melt or break.

Where do people use it?
Its main job is in high-temperature furnaces. It holds graphite boats securely. It spaces rods apart. It cushions parts during heating. It prevents pieces from touching. This avoids contamination. It is common in labs, material processing, and semiconductor work. It works where heat and purity matter.

Is it fragile?
Yes, alumina ceramic is very hard. It is also brittle. Handle it carefully. Avoid dropping it. Avoid hitting it with metal tools. Sharp impacts can chip or crack it. Protect it from thermal shock. Don’t heat or cool it too fast. Follow the manufacturer’s handling instructions.

Can I get a specific size or shape?
Yes, custom sizes and shapes are often possible. Standard sizes are readily available. Check the product listings. Contact the supplier directly for special requests. They can make spacers to your exact needs. This includes different diameters, lengths, or hole patterns.
