5 FAQs of High Temperature Trapezoidal Shape Ceramic Alumina Boat Crucible for Melting Furnace

Here are 5 FAQs about High Temperature Trapezoidal Shape Ceramic Alumina Boat Crucibles for Melting Furnaces:

What material is this crucible made from?
This crucible uses high-purity alumina ceramic. The typical purity is 99.6% or higher. This high purity gives excellent resistance to heat and chemicals. It prevents contamination of your melted materials. This makes it suitable for demanding applications.

Why is the trapezoidal shape important?
The trapezoidal shape offers practical benefits. It provides more strength than a simple rectangle. The angled sides help manage thermal stress better. Materials expand when hot. The shape allows for this expansion without cracking. This design is especially good for repeated heating and cooling cycles.

What’s the highest temperature it can handle?
These crucibles withstand very high temperatures. The maximum continuous use temperature is typically around 1700°C (3092°F). Some high-purity grades may handle up to 1800°C (3272°F) short-term. Always check the specific product rating for your needs. Exceeding the limit damages the crucible.

How much material can I put inside?
Don’t fill the crucible completely. Leave space at the top. Overfilling causes spills and uneven heating. It stresses the crucible walls. Follow the manufacturer’s recommended capacity. This is usually given as a volume or weight limit. Consider the material’s density too. Filling to 70-80% capacity is often safe.

How do I clean it and how long will it last?
Cleaning requires care. Let the crucible cool completely first. Remove leftover material gently. Avoid metal tools that scratch. Use appropriate brushes or compressed air. Avoid thermal shock during cleaning. Lifespan depends heavily on usage. Factors include peak temperature, heating/cooling speed, material melted, and handling. Proper care extends its life significantly. Expect multiple uses under normal conditions.
