Features of Inert Ceramic Balls

Inert ceramic balls have stable chemical features and a low rate of water absorption, inert ceramic balls can resist high temperatures and high pressure.

Inert ceramic balls can also resist the corrosion of acid, alkali and some other organic solvents, inert ceramic balls are able to stand the thermal shock (sharp change of temperature) during the chemical reaction process.

The main role of these inert ceramic balls is to increase the distribution spots of gas or liquid, and to support and protect the catalyst of low strength in the reactors (a column or a tower).

Inert Ceramic Balls have stable chemical features and a low rate of water absorption, resist high temperatures and high pressure, and also resist the corrosion of acid, alkali and some other organic solvents. They can stand the change in temperature during the manufacturing process.

Applications of Inert Ceramic Balls

As refractory bed top plugs and supports in order to protect the catalyst bed from thermal impurities so that the catalyst bed is kept intact in spite of wide pressure variation. Inert Ceramic Ball is widely used in petrochemical industry, chemical industry, fertilizer industry, natural gas industry and environment protection, etc.

Catalyst Bed Support media are used routinely in the following specific services:

Ammonia plants, Hydrotreaters, Bender treaters, Isomerization units, pretreaters and reactors, Molecular sieve units, Diesel hydrotreaters, Naphtha treaters, Fixed bed reformers, Reformer pretreaters, Fluidized pollution control, Hydrocrackers (1st stage), Hydrogen plants.

Inert Ceramic Balls are widely used in many fields, including:

petroleum, chemical engineering, fertilizer production, natural gas and environmental protection. They are used as covering and supporting materials of catalysts in reaction vessels and as packing in towers.

Zirconia toughened alumina ceramics (ZTA) are material of white, wear-resistant, corrosion-resistant and good chemical stability.

Alumina ceramics have high hardness and zirconia ceramics have good toughness. The most commonly method for toughening alumina ceramics is zirconia toughening. Adding an appropriate amount of zirconia to alumina, the two materials form an excellent composite material with high strength and high toughness, with better physical and chemical properties, and a wider range of applications.

ZTA has higher flexural strength, fracture toughness and excellent wear resistance.
According to the special requirements of different users, the specific ratio of alumina and zirconia can be adjusted to obtain ZTA with different properties.

The performance of zirconia toughened alumina ceramics is better than that of 95 alumina ceramics, and the price is much lower than that of zirconia ceramics; in many working conditions where alumina ceramics are not competent, ZTA shows a better cost performance than zirconia ceramics, and is widely used in mining, machinery, electronics, petroleum, chemical and aerospace,etc.

Alumina ceramics is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness.

High purity alumina ceramics are ideal for environments where resistance to wear and corrosive substances are required.

Alumina ceramic has excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential.

Alumina ceramic is the material of choice for alumina wear parts. The proven wear and heat resistance of alumina wear parts makes them ideal for the manufacture of wear-resistant components.

Alumina has a high melting point, high hardness, although mechanical strength is reduced at temperatures above 1000 C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced.

Alumina is an electrically insulating material, with a high electrical resistivity, increasing with purity.

Good chemical stability of alumina leads to high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solutions.

Testing has shown that the low chemical solubility of alumina ceramics components makes them highly resistant to chemical corrosion.

This is what makes high purity alumina the material of choice for components in a wide range of industrial applications.

Alumina Ceramics are generally white and the color is derived from either the sintering additives or impurities in the raw materials.

We make and supply alumina ceramic grinding media, abrasion ceramic lining and alumina ceramic parts & components.

We also supply zirconia ceramics.
