Purpose of a Design Specification
Calcination is the heating of an ore at high temperature. Calcium carbonate undergoes calcination to give calcium oxide. Calcium oxide doesn't undergo calcination.
Calcination is to be distinguished from roasting, in which more complex gas-solid reactions take place between the furnace atmosphere and the solids. Although calcination can only be endothermic roasting can also be exothermic.
CALCINATION This is a process in which corbon is expelled from its compound i.e cao. ROASTING This is a process in which metal is converted in to its oxide BY FARIDA REHMAN
calcination
Calcination is applied to an ore because for the extraction of carbon from an ore.Mostly the ore is consist of carbon and we can easily provide carbon from it. Calcination is generally applied to an ore because of our daily use.Iknow that my given answer is wrong but please accept it i will be thankfull to you people. THE ANSWER IS GIVEN BY FARIDA...REHMAN..... GOOD LUCK...... I KNOW YOU CAN GET A BETTER STUDY FROM IT.
A crucible is used for heating, melting or calcination of materials.
By heating kaolin below its meltig point we can have calcination of kaolin.
A calcar is a small oven or furnace used for the calcination of sand and potash.
the conversion of carbon ore into metal oxide in absence of air.
Burners are used in laboratory for heating, calcination, burning.
calcination - basically is a single step heating process where it determines either further heat treatment (sintering) is necessary or not. For example, let say BaTiO3. the reaction between BaO and TiO3 definitely will produced BaTiO3 without having intermediate phase. Although, secondary phase might presence, however, it may decrease with increasing calcination temperature. By the way, if the intermediate phase is a must for next reaction, then calcination has to be followed by sintering process (to provoke further reaction). Sintering is well-known in whiteware as to produce solid body by particle diffusion. However, regards to the calcination process which is formation of intermediate reaction need to be undergo sintering process to ensure all those reaction occur in calcination process are completely reacted to form another a very stable phase.
Crucibles are used in laboratory for calcination, melting, high temperature reactions, evaporation.
