5 FAQs of High Temperature Pure Zirconia Crucible, Alumina Rectangular Boat Ceramic Crucible

High Temperature Zirconia Crucible & Alumina Rectangular Boat: Key Questions

What makes zirconia crucibles handle extreme heat?
Zirconia crucibles use zirconium dioxide. This material has a very high melting point. It stays solid and stable much longer than many other ceramics under intense heat. This stability is crucial for melting very high-temperature metals or compounds.

Why might an alumina boat crack with sudden temperature changes?
Alumina ceramic is strong. It resists wear well. But its structure doesn’t expand or contract as easily as zirconia when heated or cooled fast. Quick temperature shifts create internal stress inside the alumina. This stress can cause cracks or breaks.

Which ceramic resists harsh chemicals better?
Alumina generally offers superior chemical resistance. It withstands attack from strong acids, alkalis, and reactive molten salts better than zirconia in many situations. This makes alumina boats good for chemical processing tasks. Zirconia can be vulnerable to certain acidic environments.

Why choose a rectangular alumina boat over a round crucible?
Shape matters for the job. Rectangular alumina boats provide a long, flat surface. This is ideal for evenly heating samples like wafers, plates, or powder beds during processes like sintering or annealing. Round zirconia crucibles are better for containing and melting larger volumes of material.

How should I clean these ceramics after use?
Cleaning needs care. Avoid harsh impacts. Let the ceramic cool completely first. Use warm water and a soft brush for loose residue. For tougher buildup, soaking in mild acid or solvent might help. Check chemical compatibility first. Never use abrasive cleaners. Thermal shock during cleaning can damage them.
