High Temperature Ceramic Crucible

Ceramic Crucible

Advantages of Using High-temperature Ceramic Crucibles

1. High-temperature resistance

High-temperature ceramic crucibles generally can withstand temperatures exceeding 1200°C. Among them, the alumina ceramic crucible can withstand a temperature of 1800°C for a short period, and the zirconia ceramic crucible can withstand a temperature as high as 2400°C.

2. Chemical stability

It has strong corrosion resistance to acids, alkalis and molten metals. For example, the alumina ceramic crucible can resist corrosive substances such as fluorides, while the zirconia ceramic crucible hardly reacts with any samples.

3. Mechanical strength and durability

The hardness of the alumina ceramic crucible is close to that of quartz, and its wear resistance is 266 times that of manganese steel. The silicon nitride ceramic crucible has both high hardness and thermal shock resistance.

Application of High Temperature Ceramic Crucible

Alumina ceramic crucibles have become a common choice in fields such as metallurgy and chemical industry due to their cost-effectiveness, resistance to acid and alkali corrosion, and wide applicability. On the other hand, ceramics such as zirconia and silicon nitride are irreplaceable in ultra-high temperature or extremely corrosive environments. One can simply make a choice according to the specific temperature, medium type, and cost requirements.

Factory Equipment

Ceramic Crucible

Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.

Injection moulding: Inject a slurry containing paraffin into a metal mold at a certain temperature and pressure, and after the body cools and solidifies, perform demolding to prepare ceramic bodies.

Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.

FAQ

Q1. What is the operating temperature for alumina ceramic crucibles?

A1. High purity (such as over 99%) alumina ceramic crucible, suitable for high temperature environments of 1650-1800 ℃.

Q2. How to clean alumina ceramic crucible?

A2. Alumina ceramic crucible after use, wipe with a soft cloth and mild detergent to avoid scratching the inner wall with hard objects.
