Advantages of high density graphite crucible<\/h2>\n

It\u00a0comes\u00a0in various styles such as straight cylindrical type, mouthed melting type, split crucible, and special-shaped basin.<\/p>\n

E<\/b><\/strong>xcellent high-temperature stability<\/b><\/strong><\/p>\n

It\u00a0can withstand a long-term working temperature of 3000\u2103 in an inert atmosphere.<\/p>\n

 <\/p>\n

D<\/b><\/strong>ense <\/b><\/strong>body<\/b><\/strong><\/p>\n

It has\u00a0extremely low porosity, which makes\u00a0it difficult for molten metals or corrosive molten liquids to penetrate and leak.<\/p>\n

 <\/p>\n

E<\/b><\/strong>xtremely strong chemical inertness <\/b><\/strong><\/p>\n

It\u00a0does\u00a0not react with metal melts such as gold, silver, copper, and aluminum, or acid-base molten salts.<\/p>\n

 <\/p>\n

F<\/b><\/strong>ast heat conduction speed<\/b><\/strong><\/p>\n

This allows\u00a0the heat in the furnace to quickly transfer to the internal materials, which results\u00a0in high melting and heating efficiency.<\/p>\n

 <\/p>\n

S<\/b><\/strong>trong thermal shock resistance<\/b><\/strong><\/p>\n

It will not crack when taken out at high temperatures and exposed to room temperature.<\/p>\n

 <\/p>\n

H<\/b><\/strong>igh hardness and structural strength<\/b><\/strong><\/p>\n

This makes it\u00a0less prone to damage during handling and loading.<\/p>\n

 <\/p>\n

E<\/b><\/strong>xcellent electrical conductivity<\/b><\/strong><\/p>\n

It\u00a0can be adapted to medium-frequency and arc-powered melting equipment.<\/p>\n

\u00a0<\/b><\/strong><\/p>\n

Uses of high density graphite crucible<\/h2>\n

The field of precious metal smelting<\/h3>\n

It has a\u00a0dense body,\u00a0free of pores,\u00a0and are chemically stable, which\u00a0does\u00a0not 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\u00a0can withstand temperatures above 1000 degrees Celsius for melting, which\u00a0can be repeatedly melted without cracking or leaking. You can use it\u00a0for jewelry processing factories and precious metal recovery enterprises for their daily batch melting of gold<\/a>.<\/p>\n

 <\/p>\n

The field of non-ferrous metal smelting and casting<\/h3>\n

You can use it in the casting<\/a> industry of\u00a0non-ferrous metals\u00a0such 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\u00a0excellent thermal shock resistance, it will not cause damage\u00a0under alternating hot and cold conditions. So it is\u00a0widely used in automotive parts hardware, cable copper materials\u00a0and alloy parts casting production.<\/p>\n

 <\/p>\n

The field of photovoltaics and semiconductor high-temperature sintering<\/h3>\n

You can use it for the purification of photovoltaic silicon materials and the sintering of silicon carbide semiconductor powder. It prevents\u00a0the silicon wafers and semiconductor raw materials from being contaminated, ensuring the yield of chips and photovoltaic materials. It conducts heat uniformly, which avoids\u00a0uneven sintering, cracking and scrapping of the products.<\/p>\n

 <\/p>\n

The field of heat treatment and powder metallurgy<\/h3>\n

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,\u00a0it\u00a0does not release impurities, which ensures\u00a0the 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.<\/p>","protected":false},"excerpt":{"rendered":"

High-density graphite crucible is a high-temperature resistant container product made from artificial graphite as the base material, through processes such as mixing, molding, multiple impregnation and firing, and graphite refining processing.
