XTL sintyron high heat resistant 95% alumina ceramic crucible with lid

Alumina ceramic crucibles with lids are commonly used in laboratory settings for the heating and melting

of materials at high temperatures. The main purpose of a crucible with lid is to provide a controlled environment

for the heating process, ensuring that the material being processed is not contaminated by external elements and

that the heat is evenly distributed throughout the crucible.

One of the main advantages of alumina ceramic crucibles with lids is their high temperature resistance. Alumina

ceramic can withstand extremely high temperatures, making it ideal for applications that involve the heating and

melting of materials at temperatures above 1000 degrees Celsius. This high temperature resistance allows for the

processing of a wide range of materials, including metals, minerals, and chemicals.

Another advantage of alumina ceramic crucibles with lids is their excellent thermal shock resistance. This means that

the crucibles can withstand rapid changes in temperature without cracking or breaking, ensuring a long lifespan and

reliable performance in high-temperature applications.

In terms of production process, alumina ceramic crucibles with lids are typically manufactured using a combination of

powder processing, shaping, and firing techniques. The process begins with the preparation of a ceramic powder, usually

alumina, which is mixed with binders and additives to form a paste. This paste is then shaped into the desired crucible

shape using a mold or other shaping techniques.

After shaping, the crucibles are fired in a kiln at high temperatures to sinter the ceramic particles together and form a strong,

dense structure. The crucibles are then carefully inspected for quality and precision before being coated with a glaze or other

protective finish to enhance their performance and durability.
