The lengthy sentence translation I rarely used raw materials, ceramics and minerals present
raw material that is used in the ceramics industry, some have come from this credit shield natural ore 1.
such as various clay (clays) Stone Horse teeth (feldspar), rocks (quartz) and housed in a sea of sand ton
2. Reflecting a bite from a natural ore and purification by chemical processes, such as the aluminum NA (alumina), which is derived from the mineral site bok (bauxite) that result from a synthesis of
;The soil is an important raw material in the production of ceramics products. Especially container that serves food (dinner ware or table ware) Their sanitary (sanitary ware) their tiles (wall and floor tile), and so there are several different types of soil may be different in structure. So that there is a difference in the sticky
.The soil may be classified as type 2 is a black and white clay, white clay and clay clay white
(China clay, Kaolin) refers to the white or black soil on soil resources of this type have a 2
.Source of origin (Residual Deposits), white clay often found this source in such a way as the mountains or Plains, which was stone horse tooth mineral sources (Feldspar), horse teeth decayed stone dismissed the crash by atmosphere (Weathering) final result remains as a white clay is that it. The movement was born in White Earth. This step of the reaction is as follows:
.Properties of soil in white
size (Particle size)
. Generally the soil granules provides strength and shrinkage when dried than coarse granular soil
shape (Shape Particle)
. The mineral Kaolinite particles it has a hexagonal sheet shape. Size from 0.5 to 10 micron size on average is between 0.5 micron
this type of clay black soil is black, but when it burns, it is white. This type of soil is clay over and make a product that has not burned in more than strength and the white soil
.Black soil may provide a definition that refers to the Earth with white black and white dark accumulation has reached the surface in that group with information granules. An organic substance contamination With good strength, strength to the products when the don't burn more than white clay. Why we need to bring the black clay used in ceramic industries
1. Enhances the ability of forming molded clay, better
2. Product development before burning, more strength and as a result cause the loss due to the fracture of a product that have not been burnt while moving down
3. Help make the soil in water, pour it with better flowability
4.Some types of black soil has the ability to cause the reaction between the mass communication. In the flesh, molding clay while burning it results in a product with the same texture as the black soil is present powerful industrial ceramics have disadvantages:
1. In the black soil, often with dirt, such as Tio2, Fe2O3 is a waste product of white makes a go
2. make a product less translucent feldspar
.Aluminum compounds are no elemental's silicate Moo I and II, there are constant elements mainly serves to help achieve
fusion at low temperature. Promote change to beef the glass causing the transparency blending in;
.Soda feldspar is Na large quantities are used as a component in coatings and water use thaet feldspar. There are plenty of K in use as an ingredient in meat, clay sculpture
quartz.An element is the most transparent silica colorless. If there is any color impurities act as structure of ceramics products. Help achieve the strength not to bend a little shrinking products
dolomite ore.Mineral or rock sediments that comprise the [CaMg (CO3) 2] is mainly look like limestone mix a little in the flesh; Reduce the melting point of the materials and mix in water, mixed oxide, compound coating on
high fire-resistant products
. Combine to make a product of glass ceramics used to make
opaque khai dik
earthy elements. But with a different crystal structure of NA
28 per cent-a-32 is a solid rock by mass taken images carved into decorations
.The 11 percent of NA-28 by mass Used to make refractory making floor tile
aluminum Diecasting na per cent lower than the above. Use is made of white cement
