CERAMIC INDUSTRY PERTEMUAN 07 Matakuliah: S0372 – Kimia Teknik Sipil Tahun: Ganjil 2007/2008
Bina Nusantara CERAMIC INDUSTRY 1.Whiteware. 2.Structural Product Clay. 3.Refraktori
Bina Nusantara Elementary Raw Material. Three special raw material which is used to make ceramic product classical, or “ triaksial”, is clay, sand and feldspar. Clay is hydrate silicate aluminium which do not too pure which is formed as result of decay of congelation rock of pregnant which of feldspar as one of the important original mineral. Its reaction can be portrayed as follows: K 2 O.Al 2 O 3.6SiO 2 +CO 2 +2H 2 O K 2 CO 3 + Al 2 O 3.2SiO 2.2H 2 O + 4SiO 2

Bina Nusantara Whiteware Whiteware is the general name given to of a kind ceramic product which usually white chromatic and have smooth texture. This Ceramic made of by elementary materials of chosen quality clay and flux in number vary heated at high temperature enough (1200 until 1500 o C) in kiln. Whiteware Type : 1.Carthenware 2.Chinaware 3.Porcelain 4.Sanitary ware 5.Stoneware 6.Whiteware tile
Bina Nusantara Product Clay Construction. Cheap goods but holding up to wear, like building brick, wall face brick, terakota, pipe of got, tiling of comber, is usually made of by cheapest ordinary clay with or without glasir. The clay usually contain some impure which is type and amount him last for giving flux energy and adhesive power. Used raw material there is three kinds of clay : 1.Clay burn to squeeze. 2.Clay burn to turn white. 3.Clay burn bur, what usually refraktori.

Bina Nusantara Refraktori. Sour Term refraktori, basa, and neutral as well as is super refraktori, including materials used to arrest;detain influence of termal, chemical and physics that goes on in kiln. Nature of Refraktori. To make most compatible refractori in certain operation, require to be paid attention used raw material, workmanship temperature in kiln, and passed to burden is warm-up time, and also reaction of chemistry that goes on. Usually, to make one kiln, needed by some type of refractori because one just type of refractori nothing that can hold up to various condition of which there are in various part of kiln.
