1. High temperature resistance: Alumina ceramic crucible boats can withstand extremely high temperatures up to 1800 ° C without deformation or melting.
2. Corrosion resistance and chemical resistance: Alumina ceramic crucible boats have strong resistance to corrosive environments and are chemically inert to most acids, bases, and molten salts.
3. Mechanical strength and hardness: Alumina ceramic crucible boats have excellent mechanical properties, including high hardness and wear resistance.
4. High thermal shock resistance: The material can withstand rapid temperature changes without cracking or breaking, which is crucial in applications where alumina ceramic crucibles boats are suddenly heated or cooled, such as in thermal cycling processes or quenching experiments.
5. Purity and low pollution: High purity alumina ceramic crucible boats ensures that the material does not introduce impurities into the sample during heating or melting.

Our factory
Jinzhou Yunxing Industrial Ceramics Co., Ltd. was established in 2000, mainly producing various types of tubular ceramic products and various industrial parts with alumina content above 99.3%. The factory covers an area of 4000 square meters.
The company's main products are: alumina ceramic tubes, alumina ceramic crucibles, alumina ceramic rods, alumina ceramic boats, alumina ceramic plates, alumina ceramic parts, etc.
The company currently has 3 1800 ° C high-temperature furnaces and 2 1400 ° C low-temperature kilns independently designed and manufactured. The molding process is mainly based on grouting molding, and has other molding process equipment such as extrusion and hot die casting. The company has 105 employees, including one senior ceramic engineer, three engineers, six overseas sales staff, and four professional after-sales staff.
FAQ
Q1. Why alumina ceramic crucible is used?
A1: Used as a material for industrial furnaces due to its ability to maintain its hardness at high temperatures. Used as a protector for high-temperature thermal couples. Used as a material for the chemical industry due to its high corrosion resistance.
Q2. What is the maximum temperature for alumina ceramic crucible?
A2: The temperature range of alumina ceramic crucible is typically between 1600°C to 1800°C.
Q3.Can you overheat a alumina ceramic crucible?
A3. Never Overheat Your Crucible – Every alumina ceramic crucible has a maximum temperature limit.
