What apparatus used to observe reactions?
Berzelius and Erlenmeyer flasks, test tubes, crucibles, cups, etc.
What kind of fire bricks are used for molten blast furnace slag?
What kind of fire bricks are used for molten blast furnace slag?
How are redox reactions used to obtain pure metals?
One way is electrolytic reduction of metal cations from molten salts. Another is heating with carbon, which can reduce the metal ions in many metal oxides to elemental metal atoms.
What is the definition of ceramic fiber square?
ceramic fibered square is a chemistry object that is used to place under a hot apparatus
How is carbon used in chemistry?
Carbon applications:- as diamond to cut glass and for polishing- as graphite for electrodes, crucibles, etc.- as pencil mine- as carbon black
What is the graphite?
a form of the element carbon (just like diamond is pure carbon). Graphite is used (with clays) in the lead of pencils, as a lubricant, for crucibles (vessels to hold high temperature molten metals), and a host of other things..
What is ceramic foam filter?
Ceramic foam filter is the refractory ceramic material. It is used for filtration of molten metal,gas,water and so on.
Are the furnaces used to melt metals insulated with ceramic materials?
Yes, this is true.
What is ceramic cutting tools?
ceramics are the materials which are non metals which can be used over metals due to low co-efficient of friction
What is picrite used for?
It's used to withstand extremely high temperatures, usually found in a workplace where molten metals are present.
What are ceramic insulators used for?
Ceramic and porcelain insulators are used in conjunction with wires that may generate a large amount of heat. Ceramics have a very high heat tolerance, especially higher than plastic and some metals.
What is a tong used for?
This tong is used to manipulate very hot crucibles.
What are the uses of sodium?
* Sodium in its metallic form can be used to refine some reactive metals,such as potassium, zirconium from their compounds. * It is used to purify molten metals. * It is used in manufacturing of soaps. * It is added in certain alloys to improve their structure.
What is a crucible tong used for?
This tong is used to manipulate very hot crucibles.
What is a tong for?
This tong is used to manipulate very hot crucibles.
What are crucible tongs?
Crucible tongs are used for taking crucibles out of the fire and are also used to move crucibles from the furnace to another location. They are used in chemistry for grabbing hot containers and are usually made out of steel.
How and why are metals such as aluminium and iron recycled?
The metals are collected and then melted at high temperature. They then have any impurities scraped off the top of the container of molten metal. The pure molten metal is then poured into casts and cooled. The blocks of metal can now be used again. It is cheaper and less environmentally damaging to recycle metals rather than extract them from their ores, in the ground.
