Specifications of High Temperature Insulated Big Size Ceramic Mullite Box Sagger Alumina Boat Crucible

Here’s the product description for the ceramic sagger:

This huge ceramic mullite box sagger is created high warm. It deals with extremely hot temperatures. We build it challenging. The main things within is mullite and light weight aluminum oxide. This mix is good. It resists heat shock well. Points obtain very hot inside heating systems. This sagger stays strong. It won’t break easily from quick temperature level modifications.

The sagger allows. It holds big quantities of material. You can use it for firing porcelains or heat-treating metals. It works well for sintering powders also. We make it thick. The thick walls keep warmth steady. This secures your items inside. Heat stays also. Your outcomes are much better.

This sagger gets to very heats safely. It can deal with as much as 1700 levels Celsius. It holds that warmth for long period of time. The product doesn’t thaw or warp. It lasts much longer. You save cash over time. You will not need to change it often.

The sagger is available in plus sizes. We offer various dimensions. Usual dimensions allow. Assume 300mm long, 200mm broad, 150mm high or bigger. We can make custom-made dimensions too. Just ask about your requirements. We will certainly locate the appropriate fit.

The surface area is smooth. This quits things from sticking. Cleansing is easier. You can utilize it lot of times. Manage it meticulously. Don’t drop it. Check for fractures first before using it once more. It’s tough but still ceramic.

Applications of High Temperature Insulated Big Size Ceramic Mullite Box Sagger Alumina Boat Crucible

This ceramic mullite box sagger, additionally called an alumina watercraft crucible, takes care of extreme warmth. It’s constructed large for larger industrial tasks. Its main work is shielding valuable things inside high-temperature furnaces. Believe temperatures over 1500 ° C and even 1700 ° C. Routine materials can not cope with that type of warm.

Its special mullite-alumina mix gives it extremely thermal security. This suggests it resists warping or cracking under extreme warm cycles. It also has low thermal shock. You can heat it up quickly or cool it down quick. It will not damage quickly. This durability makes it last lengthy. You do not need to replace it often.

Where do people really use these large ceramic boxes? Heat treatment heaters rely upon them. They hold metal parts during processes like annealing or sintering. The crucible guards the components from straight flame or heater gases. This maintains the parts clean and prevents contamination.

Powder processing is one more large location. These saggers hold powdered products like ceramics or specialized chemicals throughout calcination. The high warm repel impurities or changes the product’s structure. The crucible contains the powder securely throughout the lengthy heating cycle.

Research study laboratories need them also. Scientists use them for high-temperature experiments. They examine new materials or research reactions under severe problems. The crucible gives a stable, inert container.

Crystal development makes use of these crucibles. Expanding large solitary crystals calls for extremely high, controlled warmth. The mullite crucible holds the raw materials. It withstands the lengthy process times without deteriorating.

The semiconductor sector utilizes them for certain tasks. They bring silicon wafers or various other delicate parts via high-heat furnace areas. The ceramic shields the wafers. It stops contamination from heater wall surfaces or elements.

5 FAQs of High Temperature Insulated Big Size Ceramic Mullite Box Sagger Alumina Boat Crucible

High Temperature Insulated Big Size Ceramic Mullite Box Sagger Alumina Boat Crucible: Key Questions Answered

What material is this crucible made from?
Our crucible uses top-grade mullite and alumina ceramics. These materials offer exceptional resistance to heat. They resist chemical corrosion very well. This ensures long life in demanding conditions.

How much heat can this crucible handle?
It reliably withstands temperatures up to 1700°C (3092°F). Its excellent insulation keeps heat inside effectively. This makes it ideal for high-temperature sintering, firing, and crystal growth processes. You get consistent results.

What sizes are available?
We offer big sizes to meet industrial needs. Common dimensions include lengths from 100mm to over 500mm. Widths and heights vary accordingly. Custom sizes are possible too. Contact us for specific requirements.

Is it resistant to sudden temperature changes?
Yes, thermal shock resistance is a major strength. The mullite/alumina mix handles rapid heating and cooling cycles well. Your crucible won’t crack easily under normal use. This reduces replacement costs significantly.

How do I clean and maintain it?
Allow the crucible to cool completely first. Remove residue with a soft brush or compressed air. Avoid harsh chemicals or metal tools. They can damage the surface. For stubborn buildup, very light sanding might work. Inspect regularly for cracks.
