High Density Graphite Crucible

Advantages of high density graphite crucible

It comes in various styles such as straight cylindrical type, mouthed melting type, split crucible, and special-shaped basin.

Excelente estabilidad a altas temperaturas

It can withstand a long-term working temperature of 3000℃ in an inert atmosphere.

Dense body

It has extremely low porosity, which makes it difficult for molten metals or corrosive molten liquids to penetrate and leak.

Extremely strong chemical inertness

It does not react with metal melts such as gold, silver, copper, and aluminum, or acid-base molten salts.

Fast heat conduction speed

This allows the heat in the furnace to quickly transfer to the internal materials, which results in high melting and heating efficiency.

Strong thermal shock resistance

It will not crack when taken out at high temperatures and exposed to room temperature.

High hardness and structural strength

This makes it less prone to damage during handling and loading.

Excelente conductividad eléctrica

It can be adapted to medium-frequency and arc-powered melting equipment.

Uses of high density graphite crucible

The field of precious metal smelting

It has a dense body, free of pores, and are chemically stable, which does not react with the precious metals. So the molten precious metals will not seep into the casting material and cause loss, ensuring the purity of the finished products. And it can withstand temperatures above 1000 degrees Celsius for melting, which can be repeatedly melted without cracking or leaking. You can use it for jewelry processing factories and precious metal recovery enterprises for their daily batch melting of oro.

The field of non-ferrous metal smelting and casting

Puede utilizarlo en el fundición industry of non-ferrous metals such as aluminum, copper, tin, and zinc. It can resist the erosion and corrosion of the metal melt, which will not introduce impurities to change the alloy composition. Because of the excellent thermal shock resistance, it will not cause damage under alternating hot and cold conditions. So it is widely used in automotive parts hardware, cable copper materials and alloy parts casting production.

The field of photovoltaics and semiconductor high-temperature sintering

You can use it for the purification of photovoltaic silicon materials and the sintering of silicon carbide semiconductor powder. It prevents the silicon wafers and semiconductor raw materials from being contaminated, ensuring the yield of chips and photovoltaic materials. It conducts heat uniformly, which avoids uneven sintering, cracking and scrapping of the products.

The field of heat treatment and powder metallurgy

You can also use it in the powder metallurgy and hard alloy sintering process for holding the powder materials. Due to its thermal shock resistance, it does not release impurities, which ensures the purity of the alloy during sintering. And it is suitable for the rapid temperature rise and drop process of the vacuum furnace, which will not crack or leak.
