Porcelain Crucible

Description

A porcelain crucible is a small, cylindrical, and typically shallow container made of porcelain, a type of ceramic material. These crucibles are commonly used in laboratories and various industrial applications for heating, melting, and calcining substances at high temperatures.

Features of Porcelain Crucible

• The volume range is from 20 mL to 300 mL.
• Good temperature resistance, long-term use at 1600°C, short-term 1800°C.
• Porcelain crucibles are made from high-quality, heat-resistant porcelain ceramics, which can withstand very high temperatures without melting or deforming.
• High density is achieved through slip casting. It has high-purity alumina and good chemical corrosion resistance.

Advantages of Porcelain Crucible

• Porcelain crucibles are durable, can be used repeatedly, and are cost-effective.
• They are versatile and can be used to heat, melt, and calcine a variety of substances.
• The smooth, non-porous surface is easy to clean and effectively prevents contamination.
• Porcelain crucibles are more cost-effective than crucibles made of some other materials.

Applications

• Heating and evaporating liquids.
• Melting and fusing metals and metal oxides.
• Conducting high-temperature experiments in laboratories.
• Calcination of substances to remove volatile components.
• Ignition and ashing of organic and inorganic samples for quantitative analysis.

When using porcelain crucibles, it’s important to handle them carefully. Sudden temperature changes can cause them to crack or break, so they should be preheated gradually. Additionally, they should be cooled slowly to avoid thermal shock.

After use, porcelain crucibles can be cleaned by brushing, scraping, or soaking to remove any residual materials. They should be cleaned thoroughly to avoid contamination in subsequent experiments.

Tips: While porcelain crucibles are versatile and widely used, it’s important to note that they may not be suitable for extremely high-temperature applications where more specialized materials like graphite or certain types of ceramics would be preferred.
