Wollastonite is a calcium, silicon, and oxygen-based industrial mineral. It is generally white, although it can also be colorless or gray. CaSiO3 is the molecular formula of Wollastonite. 2.86-3.09 is the specific gravity of it.
What are the Purposes of using Wollastonite?
Wollastonite increases weather resistance, lowers brightness and coloring, and works as a flatting and suspension agent, as well as performing as a smoothing and suspending agent.

What are the Uses in Ceramics?
Wollastonite is used in the manufacture of ceramics. It reduces firing and drying shrinkage, and lowers the temperature at which the glasslike stage is constructed. It minimizes instability and glaze problems in ceramic production and reduces shrinkage and gas expansion.
What are the other Applications?
In spite of being used in ceramics, wollastonite is also used in plastics, steel, and in the production of paints and coatings.
Alumina is a chemical compound that is formed of aluminum and oxygen with the formula Al2O3.It is called Aluminium Oxide. It has melting and boiling points of 2072 C and 2977 C, respectively. Aluminum Oxide has a density of 3.95 g/cm3.
Why is Alumina powder used in ceramics?
Although Alumina is an electrical insulator, it has a high heat transmission for a ceramic. Water does not melt Alumina. So, it is used in ceramics.

How is alumina powder made for ceramics?
Alumina are manufactured in ceramics from white particles or a smooth dense powder purified from bauxite. Alumina is a strong, long-wearing industrial ceramic which can only be produced via diamond cutting.
What are the Uses in others?
Alumina is a great element for bricks, plastics, polymers, and heavy clayware since it is chemically stable. It is also a popular component in sandpaper and a cost-effective alternative to industrial diamonds.
What are the Side effects?
Although Alumina is a beneficial metal, it is a skin irritant and it is also harmful for the environment. Itâ??s definitely uncomfortable in some cases
Composed glaze is a thin layer of liquid of different combined glaze materials which is put on ceramic tableware, sanitary ware or tiles and makes it so much hard and shiny when those are heated in very high temperature.
What are the classifications?
Composed Glaze for Tiles
Composed glaze for Tableware
What are the specifications?
Ceramic glaze has five basic components. These components are silica, alumina, flux, colorants and modifiers. Even though all glazes are made up of the same components. However, Glazes need a balance of three main ingredients: Silica, Alumina and.

How do Ceramics Glaze work?
Composed Glazes are vitreous by their nature. When glaze is fired onto a piece it is like covering the piece with glass. It seals the piece stain resistant. The same glaze can also turn different colors when fired to different temperatures. It also gives a tougher surface.
What is the Purpose of applying Composed Glaze in Ceramics?
Composed Glaze is used to serve color, decorate and waterproof to a ceramic product. Moreover,Composed glaze can enhance the fired clay body on an aesthetic and a functional level. Visually, Composed glaze can be decorative and a great source of color and texture. Practically, once this glaze can seal clay bodies fired, making them waterproof and food safe
The mixture of silica and fluxes which is fused at high temperature to make glass. A frit is a type of ceramic glass that predominantly consists of silica, di boron trioxide and soda. This combination of raw materials are industrially melted and rapidly cooled. Frits form an important part of the batches used in compounding enamels and ceramic glazes. Not all glasses that is fused and quenched in water is frit, as this method of cooling down very hot glass is widely used in glass manufacture.
What are the Classifications?
Opaque Frit: It has lower or higher coefficient of thermal expansion, water anti- penetration ability, wide firing range, low softening point, resist to crazing.
Transparent Frit: Excellent gloss & color development frit, often used in single fast firing wall and floor tiles, High Transparently glossy glaze suitable for rustic or homogeneous tiles.
How does a Ceramic Frit make?
Ceramic frits are obtained by fusing raw materials in a melting kiln at higher temperature. The melt is cooled quickly, either by quenching in water which transforms it into a fragmented solid that is practically insoluble in water.
What are the Uses in ceramics?
Because of their various applications, there are numerous types of frits, each with specific uses. Despite the diversity, manufactured frits typically all contain more than one kind of flux (for melting) and are stabilized with alumina and silica. This causes the frits to be more reliable in consistently reproducing glazes
Grinding mill balls or Alumina balls are used in processing equipment to improve bearing performance. Alumina oxide balls are lighter, stiffer, smoother, harder, corrosion resistant, require less lubrication and have a lower thermal than others.
What are the properties of Alumina Mill Ball?
Alumina oxide is a top choice of ceramic balls due to its corrosion resistance and high operating temperature capabilities. They have a low water absorption rate and stable chemical features. They can resist high pressure and high temperatures and also can withstand the corrosion of alkali, acid and many organic solvents. It has high density and almost perfect roundness with smooth surface for higher grinding efficiency. The excellent wear resistance, higher impact strength to save your running cost and less contamination.

What are the purposes of using Mill Ball?
The primary role of inert alumina mill balls is to boost the spots of gas and liquid distribution. They also offer support and protection to the activating catalyst with low strength. Additionally, during the manufacturing process, temperatures change to higher temperatures. Inert alumina ceramic balls can resist those harsh temperatures.
What are the applications of Mil Ball?
It is widely used a process of grinding, mixing and dispersion. It is also used in engineering ceramics, ceramics capacitor, Tiles, Sanitary ware, Porcelain, Pigments, Enamels, Cement, Abrasive compounds etc. It is also used in other fields like paints, chemicals, electronics and plastics. Because of their durability, alumina oxide balls have a variety of heavy-duty and industrial uses. For example, the use of alumina oxide balls allows industrial bearings to run at higher speeds and higher temperatures
