Silicate vs Silicone: What's the Difference?

If you are not a chemist or those who are associated with the field, you may feel confused about silicate vs silicone. They share a similar appearance, pronunciation, and close relationship with silicon. What are they exactly and what’s the difference between them? We will explore that in this article.

What is silicate?

From the angle of chemistry, silicate is a kind of compound composed of silicon, oxygen, and other chemical elements, mainly some metallic elements. Simply speaking, silicate is a salt that contains silicate ions, widely existing in the earth’s crust, serving as a fundamental component of most rocks, such as granite, and soils.

Silicates have stable chemical properties, such as high hardness and heat-resistant capability, which makes them a crucial raw material in the silicate industry. We can find them in many daily staff as they are used in the production of refractory materials, glass, ceramics, cement, and more.

The silicate industry is an important sector of inorganic chemical manufacturing, referring to the industry that produces various finished products and materials predominantly composed of silicates, including ceramics, glass, enamel, cement, and refractory materials.

This industrial domain is often referred to as the "kiln industry" due to its reliance on kilns as primary equipment during the firing or melting processes. Silicate materials, as a significant category of inorganic non-metallic substances, hold a prominent position alongside metals and polymers as one of the three major materials in modern industry.

What is silicone?

Compared with silicate, silicone is no doubt more famous for common people due to its popularity in daily staff like cookware and kids’ toys. However, to figure out the relationship and difference between silicate vs silicone, we still have to find the conception of silicone.

Silicone is a highly active adsorption material and belongs to the category of non-crystalline substances. It is a synthetic polymer composed of natural silicon, oxygen, carbon, and hydrogen elements, occupying a unique space between synthetic rubber and synthetic plastics.

Its chemical properties are stable, able to withstand extreme temperatures from -40 to 220 °C without affecting its physical properties. Silicone can be categorized into single-component and two-component types, typically classified as organic silicone and inorganic silicone based on their properties and components.

In addition to its ability to withstand extreme temperatures, silicone is also easy to manufacture and mold into various forms. It can be used to create flexible rubber-like items, rigid plastic resins, and viscous liquids that can be spread.

To sum up, silicone showcases excellent properties which can be concluded with 4 major advantages: withstanding a large temperature range, safe and non-toxic, good water resistance, and long service life. Hence, it is widely used in many aspects nowadays.

What is the difference between silicate vs silicone?

After introducing the basic knowledge about the two substances, we know that the first difference between silicate vs silicone is that they are composed of different elements. The silicate is composed of silicon, oxygen, and some metallic elements while silicone is a synthetic polymer composed of natural silicon, oxygen, carbon, and hydrogen elements.

Besides, the major method to produce silicone is to precipitate sodium silicate with acid, followed by the removal of soluble salts and subsequent drying. As we know sodium silicate is a commonly used silicate compound, therefore, we can easily get a conclusion that it is a key raw material in the production of silicone. That’s the most direct relationship between them.

What is silicone used for?

As we mentioned before, silicone is been famous in various production industries due to its excellent properties. Here we will give a brief introduction to its applications, mainly from two aspects: daily life and industries.

In people’s daily life:

1.Silicone products are integral components of items such as photocopiers, keyboards, electronic dictionaries, remote controls, toys, and silicone buttons.

2.They are used to create durable gaskets, encapsulation materials for electronic components, and maintenance materials for automotive electronics.

3.Silicone also plays a crucial role in construction and repair projects, including sealing joints on highways and bridges.

4.Furthermore, it is used in baby products, kitchenware, medical device components, and more due to its non-toxic, odorless, and versatile properties.

In industry:

1.Silicone is employed to provide high-temperature safety protection for facilities exposed to extreme conditions, such as heat, flames, radiation, and chemicals, ensuring operational safety and cost efficiency while reducing energy consumption.

2.It is also utilized in various industrial processes, including drug purification, DNA separation, food drying, high-precision electronics, advanced cosmetics, wastewater purification, beer purification, high-performance coatings, and resin production or preservation.

Above is to simply list the applications of silicone, as industries continue to evolve, we believe that silicone is increasingly adapted for industrial protective equipment and more.

Conclusion:

After the discussion, we can get the conclusion that the major differences between silicate vs silicone lie in their composition, properties, and applications. Silicate is also one of the important materials to produce silicon. Even though they exhibit many differences, the confirmed point is that both of them will play a more significant role in future industry development.
