Chemicals for the ceramic industry

 I.Introduction:

Ceramics production is a process that combines art and science. Ceramics is one of Vietnam's traditional crafts, with more than 300 years of history. Vietnamese ceramic products are highly appreciated for their artistry and quality. To create beautiful and high-quality ceramic products, manufacturers must use many different chemicals. In this article, we will learn about ceramic chemicals and their role in ceramic production along with their features, applications and importance. You will gain a better understanding of how these chemicals can improve the quality and aesthetics of ceramic products.
 
 
 
II. Types of chemicals for the ceramic industry:
1. Smoothing chemicals
Smoothing chemicals are used to improve the gloss and smoothness of ceramic surfaces. They can be used to smooth the surface after the ceramic is fired or to smooth the surface before the product is fired. Common types of smoothing chemicals in ceramic production include:
 
a. Aluminum silicate:
This is the most common type of smoothing chemical in ceramic production. It helps create a glossier and smoother surface for the product.
 
b.Metal oxide:
This chemical is also used to smooth the surface of ceramic products. It can also be used to improve the aesthetics of the product.
 
c.Coating:
In addition to creating a protective layer for ceramic products, coating can also be used to improve the gloss and smoothness of the product.
 
 
 
2. Disinfectant chemicals
Disinfectant chemicals are used to kill bacteria and viruses on the surface of ceramic products. It helps increase product hygiene and minimize risks for users. Common types of disinfectant chemicals in ceramic production include:
 
a.Chlorine:
This is the most common disinfectant chemical in ceramic production. It is used to kill bacteria and viruses on product surfaces.
 
b.Ozone:
This chemical can also be used to sterilize ceramic products. It is considered a safe and effective disinfection method.
 
 
 
3.Color chemicals
Color chemicals are used to create color on the surface of ceramic products. They are mixed into the liquid before the product is fired, and will create color once the product is finished. Common color chemicals in ceramic production include:
 
a.Metal oxide:
This chemical can create many different colors for ceramic products. For example, iron oxide can produce red, copper oxide can produce blue.
 
b.Aniline color:
This is a common color chemical in ceramic production. It can produce many different colors and is easily mixed with other chemicals to create unique colors.
 
c.Cobalt, Cobalt, Cobalt
 
 
4. Shaping chemicals and molding aids
Shaping chemicals are used to create shapes for ceramic products, making clay flexible and making it easier to design the product's shape. They are added to the liquid before the product is fired, and will help the product retain its shape after firing. Common shaping chemicals in ceramic production include:
 
a.Bentonite:
Bentonite is a mineral-rich clay used in ceramic production. It is added to glazes to create good plasticity and adhesion, to increase the viscosity of clay and to minimize shrinkage when manufacturing ceramic products. Bentonite is also used as a coloring agent and helps increase the shine of ceramic products.
 
b.Kaolin - Kaolin:
Kaolin is a white clay, a fine mineral used as a raw material for ceramic production. It is waterproof and durable, so it is used to create beautiful glossy surfaces on ceramic products. Kaolin also helps reduce product shrinkage when fired.
 
Kaolin has high purity and is used as a clay supplement, helping to increase the plasticity and adhesion of the clay.
 
c. Sodium silicate:
Sodium silicate is used as a binder in the production of ceramics. It helps bind clay particles together, creating a larger and more durable mass.
 
 
 
5. Burning aid chemicals
Firing aid chemicals play an important role in firing ceramic products. Thanks to these chemicals, the product can be fired at higher temperatures and achieve the desired hardness. The most common calcination aids are silica, feldspath and copper ore.
 
6. Lighting chemicals
Light-enhancing chemicals help ceramic products become shiny and more beautiful. The most common light enhancing chemicals are titana oxide, zinc oxide, and borax
 
a.Titanium oxide
It is added to white and black glazes to create different colors. Titanium oxide also has scratch-resistant properties and helps increase the gloss of ceramic products.
 
7. Shine aid chemicals
Gloss aid chemicals are used to create a glossy layer on the surface of ceramic products. The most common polishing chemicals are lead oxide and ground silica.
 
In addition, there are also a number of other chemicals such as crystal aids, foaming aids, plasticity aids, adhesiveness aids...

 

8. Chemicals increase hardness

Hardening chemicals are used to increase the hardness of ceramic products. This helps minimize the rate of product breakage during production and transportation.
 
a.Feldspar
Feldspar is a mineral widely used in ceramic production. This is a major component of clays and is used to create white and colored clays. Feldspar also helps increase the durability and hardness of ceramic products.
 
 
 
9. Chemical molding aids:
Forming aids are used to increase the viscosity of clay during the production of ceramic products. This makes the product easier to mold and retain its shape when heated. Some common heavy-duty chemicals used in the ceramic industry include aluminum silicate, magnesium oxide, and clay powder.
 
Dolomite: dolomite is a mineral used as a fusing chemical in ceramic production. It has the ability to increase the viscosity of clay and make the final product smoother.
 
10. Liquid aid chemicals:
Liquid aids are used to reduce the viscosity of clay during the production of ceramic products. This makes the product easier to mold and minimizes the possibility of breaking when cooked. Some common liquid aid chemicals used in the ceramic industry include sodium silicate, potassium silicate, and iron sulfite.
 
11. Activated clay
Activated clay is a chemical used to improve the properties of clay during ceramic production. It helps increase the viscosity of the material and improve the heat resistance of the product.
 
With these ceramic industry chemicals, manufacturers can create beautiful and high-quality ceramic products. However, it should be noted that the use of these chemicals can also affect the health of the user, so safety measures should be taken when using them.
