Description

The gold melting crucible is mainly made of crystalline natural graphite. The Graphite crucible has good thermal conductivity and high temperature resistance. It has strong corrosion resistance to acid and alkaline solution and has excellent chemical stability. Quartz crucible is mainly made of High purity quartz sand, it has the advantages of high purity, high temperature resistance, good heat preservation, energy saving, stable quality, etc. Because of their excellent performance, graphite crucible and quartz crucible are widely used in the metallurgy, foundry, machinery, chemical and other industrial sectors for the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys.

 Quality Stability

Under high pressure and quality guarantee system, it will fully ensure the stability of quality.

 

High Heat Conduction

High content of fixed carbon ensures the good heat conduction. It also shortens the time of dissolution. Furthermore, itremarkably reducesthe energy consumption.

 

 Thermal Stability

According to the quench acute thermal using conditions of graphite crucible. It is designedto ensure the reliability of product quality.

 

Corrosion Resistance

Even and fine basic design will delay the erosion of the graphite crucibleand quartz crucible.

 

Impact Resistance

Graphite crucible can bear high thermal impact, so can carry out all process.

 

Acid Resistance

The adding of special materials will greatly improve the quality of graphite crucibleand quartz crucible for gold melting. Especially its index of acid resistance. And will prolong the service life of crucible.

 

Control of Metal Pollution

The component of material is under strict control. It ensures that graphite crucible and quartz crucible will not pollute the metals when dissolving.

 

Using in High Temperature Process

thermal expansion coefficient is small. It has resistance strain performance to hot and cold. Strong corrosion resistance to the acid and alkali solution;

Graphite Crucible & Quartz Crucible

Graphite gold melting crucible is a container applied to hold metal for smelting in a furnace. And it’s available to smelt metals under the extreme temperatures. Hence the crucible material must have a much higher melting point than the melted metal and also it must have good strength even when white hot.

Besides, graphite crucible for gold melting can withstand the high temperature, and has good resistance to chemical erosions and thermal shock.

It is generally applied for melting precious metal such as gold melting, silver melting, platinum melting, etc. Additionally, graphite crucible is also suitable for aluminum melting, copper, stainless steel and etc.

Graphite crucible and quartz crucible should be stored in dry place and do not get it wet. After drying the crucible, don’t make it touch with water. Also be careful not to give a mechanical impact force, not from a fall or impact.

What is a melting crucible made of?

Modern crucibles may be small laboratory utensils for conducting high-temperature chemical reactions and analyses or large industrial vessels for melting and calcining metal and ore; they may be made of clay, graphite, porcelain, or a relatively infusible metal.

Can you melt brass in a steel crucible?

Yes, but you will want to get a new crucible for each metal you melt. Cast iron has a higher melting point than brass, so if your furnace can do cast, then brass should be a piece of cake. Brass is a mix of copper and zinc.

What does a crucible symbolize?

The Doll in the Proctor’s house is a traditional symbol of voodoo and witchcraft. It symbolizes the transformation of good to evil. Nowadays, the doll represents childhood innocence and brings happiness.

What is the purpose of a crucible?

In chemistry, a crucible is a kind of laboratory equipment that is usually a cup, made of porcelain or non-reactive metal, used to heat chemical compounds to very high temperatures using a bunsen burner. One of the earliest uses of platinum was as a material in crucibles.
