Ball clay is a type of clay known for its fine grain, high plasticity, and ability to fire to a bright, nearly white color. It's primarily used in the production of ceramic whiteware, sanitaryware, wall and floor tiles, and tableware. Ball clay is also utilized in refractories, electrical insulators, and as a filler in various other industries.
Here's a more detailed look at the uses of ball clay:
1. Ceramics:
- Whiteware:Ball clay is a crucial ingredient in the production of fine porcelain and earthenware, contributing to its shapeability and strength.
- Sanitaryware:Its plasticity and green strength (strength before firing) make it ideal for manufacturing durable sanitaryware items like toilets and sinks.
- Tiles:Ball clay is used in the production of wall and floor tiles, contributing to their fine finish and density.
- Tableware:It helps to achieve the desired shape and green strength in the production of tableware, according to Sanitaryware.Info.
2. Refractories:
- Kiln Insulation: Ball clay's ability to withstand high temperatures without changing its chemical composition makes it suitable for use in kiln insulation and other refractory products.
- Refractory Bricks: The plasticity of ball clay allows for the shaping of refractory bricks.
3. Electrical Insulators:
- Porcelain Insulators: Ball clay's insulating properties make it suitable for use in the production of porcelain insulators and other electrical insulation materials.
4. Other Applications:
- Building and Construction: Ball clay can be used as a filler in various building materials like adhesives, sealants, and polymers.
- Agriculture: It can be used as a soil amendment, helping to improve soil structure and water retention.
- Horticulture: Ball clay can be used as a filler or amendment in horticultural products.
- Paint: Ball clay can be used as a filler in paints, according to Zillion Sawa Minerals Pvt. Ltd..
- Rubber and Plastics: Ball clay can be used as a filler in rubber and plastic products.
