The growing capacity to purify, epand and distinguish ceramic materials has led to application of ceramics processing into the field of science. I general, hat is applied on the material for the production of the ceramic as well as on other raw materials in order to develop a unbending product. Fr ceramic products that make use of naturally occurring materials like rocks and minerals, tere is a need for special processing of the materials. Tis helps in controlling the transparency, sze of particle, dstribution of the particle sizes, of the materials.

Al these factors have a significant effect on the final product being developed, wich is the finished ceramic. I case of some ceramic materials, te starting materials used for processing include powders that are prepared chemically. Wth the help of accurate chemical compositions and sizes of particles the synthetic materials may be used to control the production of these powders (Ceramic Processing). Oce this step is achieved, te ceramic materials are transformed into particular shapes. Wter and additives are added to the material for this purpose a shape forming process is applied on the materials.

Te forming techniques that are most commonly used for the purpose include extrusion, sip casting, pessing, tpe casting and injection molding. Oce the formation of the ceramics is complete, agreen color of the ceramics would be obtained. Hat is then applied on this formed material which is a treatment referred as firing or sintering that leads to the production of a finished product rigid in nature. I some cases a glazing process is also applied, prticularly where the products electrical dnnerware and tiles.

Cramics processed for highly developed applications may undertake a machining and/or a step for polishing the materials such that they can meet specific criteria for engineering design (Ceramic Processing). Tus the basic steps involved in the processing of ceramic products include procurement of raw materials, bneficiation, mxing, frming, geen machining, dying, pesenter thermal processing, gazing, fring, fnal processing and packaging. Bneficiation refers to the process that includes comminution, prification, szing, cassification, clcining, lquid dispersion, ad granulation of the raw materials before proceeding for the steps. Wth help. ..
