SiC crucible sagger
Silicon carbide crucibles are generally made of carbon bonded silicon and graphite materials. Silicon carbide crucibles are suitable for smelting and melting precious metals, base metals and other metals in an induction furnace. They are used at a temperature reaching 1600 degree celsius.
The silicon carbide crucible offers a uniform and consistent temperature when melting and has a high strength and resistance to cracking. The uniform temperature gives a high quality molten metal needed for casting long lasting and good quality metal products.
Silicon carbide crucibles have good thermal conductivity, high strength, low thermal expansion, oxidation resistance, resistance to thermal shocks, resistance to wetting, high hardness and wear resistance.
Due to the silicon carbide crucible properties, it is applicable in various industries such as, chemical, electron, semiconductor, metallurgy, etc.
Graphite Crucibles
Graphite Crucibles are refractory containers specially shaped for metallurgical operations. These are made of a mixture of Graphite, Refractory Clay, Grog and other additives. ... The crucibles are available with or without spout. These crucibles are used for melting ferrous, non-ferrous metals alloys and noble metals.
A graphite crucible is a container used for melting and casting non-ferrous, non-iron metals such as gold, silver, aluminum, and brass. The main reason graphite crucibles are popular as a manufacturing tool is their thermal conductivity, high temperature resistance, small thermal expansion coefficient for high temperature applications, and their anti strain properties to rapid heating and cooling. They are corrosion resistant to acids and alkaline solutions and have excellent chemical stability.
Graphite can be produced from natural graphite that is a naturally occurring crystalline form of carbon. This form of graphite is manufactured by combining graphite with fire resistant clay or carbon dioxide.
Synthetic graphite is produced by processing petroleum pitch and petroleum coke, which are byproducts of the oil refining process. It has a purer high fixed carbon content with very few impurities and a low sulphur content.
The quality of a graphite crucible is determined by how it is manufactured, which influences its structure, density, porosity, and strength.
There are three methods for shape forming, which are extrusion, vibromolding, and isostitcal pressing.
Refractory ceramic sagger crucible
Ceramic sagger is widely used for high temperature furnace furnitures in industrial ceramics, structure ceramics, chemical materials and magnetic materials industry.
Ceramic sagger is a ceramic boxlike container used in the firing of pottery to enclose or protect ware being fired inside a kiln. Traditionally, saggars were made primarily from fireclay. Refractory Ceramic Sagger is used for calcining all kinds of special powder such as lithium battery ternary materials especially 523,622, lithium cobalt oxides and other similar materials. In the firing process, the saggar shows the characteristics of high temperature resistance, non-stick, no reaction, long life and alkali resistance.
Product Introduction
Properties of Ceramic Kiln Sagger for Powder Calcination

They are widely used in firing kilns in the production of mosaic, square bricks, tableware ceramics, sanitary ware ceramics, roofing tiles, magnetic materials and advanced ceramics.
The product received universal acclaim from customers. The main specifications are: Pad plate, shed plate, push plate, sagger, ceiling panel, pillars and burner brick.
Refractory Sagger
Due to the material heat capacity and thermal expansion are small, the product‘s cycle using frequency is high. It is suit for below 1300 ℃ powder forging burn. It is formed by slip casting. Can be customized in a variety of shapes,
The quality of saggers will influence on the product quality and cost. Saggers with good quality shall meet the following conditions:
1) Greater mechanical strength;
2) Good thermal stability;
3) No deformation under a certain high temperature load;
4) Higher refractoriness;
5) Good thermal conductivity;
6) Small residual shrinkage.
High alumina saggar, corundum saggar, cordierite mullite saggar are widely used in various ceramic, glass, electronic, chemical,ferrite industry roller kiln, tunnel kiln, shuttle kiln, push plate kiln and other industrial kiln. Mainly used for sintering magnesium oxide, zirconia, rare earth and various powders.

Alumina ceramic crucible
According to the difference in Al2O3 content, the ordinary type alumina ceramic series is divided into 99 ceramics, 95 ceramics, 90 ceramics, 85 ceramics etc. The ceramics with Al2O3 content of 80% or 75% is also classified as ordinary alumina ceramic series.
alumina ceramic materials are used for producing high-temperature crucible, refractory furnace tubes and special wear-resistant materials such as ceramic bearings, ceramic seals and valve films and so on.It has been used for decades in electrical components for its high electrical insulation, and is widely used in mechanical parts for its high strength, and corrosion- and wear-resistance.
Boron nitride ceramic crucible
Excellent electrical insulation and thermal conductivity make BN very useful as a heat sink in high-power electronic applications. Its properties compare favorably with beryllium oxide, aluminum oxide, and other electronic packaging materials, and are easier machinable to desired shapes and sizes.
Temperature stability and excellent resistance to thermal shock make BN the ideal material in the toughest high-temperature environments such as equipment for plasma arc welding, diffusion source wafers, and semiconductor crystal growth equipment & processing.
BN is inorganic, inert, nonreactive with halide salts and reagents, and is not wet by most molten metals and slags. These characteristics, combined with low thermal expansion, make it ideal for interface materials used in various molten metal processes.
Fire Assay Crucible Clay Crucible
This relatively simple looking ceramic (we call them pots) made of fire clay and proprietary additives, has an extremely long history in the gold business. Its use is referenced in historical texts that are more than 3000 years old, which when you think about it, is no surprise really. A crucible is, in simple terms, a ceramic cup.
The crucible is used for the first part of the fire assay fusion process. The following process is typical:
Flux and sample are added to the crucible
The above additions are mixed together inside
Heat is applied to the crucible and mixture by placing the pot in a furnace at > 1000oC
After a pre-determined period of time the crucible is removed and the molten contents are poured into a cast iron mould
The crucible is cooled and ready for it’s next use however, it may be disposed of if the previous sample contained high quantities of gold.
