Through the use of modern facilities and an obligation towards innovation, we provide reliable solutions to the needs of our diverse clientele. They are specialist in calcium carbonate manufacture, providing high quality and efficiency thus being the most preferred partner for businesses looking for consistent mineral solutions.

Production Process:

• PCC: Synthetically produced by controlled chemical reaction, mostly with calcium hydroxide (slaked lime) and carbon dioxide.
• GCC: Manufactured by the mechanical grinding and crushing of natural limestone or marble extracted from quarries.

Purity:

• PCC: Purity is higher since it is produced in a controlled process leading to fewer impurities.
• GCC: The impurities in it may be from the natural sources used in its production, like the other minerals in the limestone or marble.

Particle Size and Shape:

• PCC: Rhombohedral or scalenohedral shapes are quite typical among particles that are fine and uniform.
• GCC: Particle size and shape depend on the process of grinding and the quality of the natural source, leading to particles of bigger and irregular size.

Surface Area:

• PCC: Normally has a greater surface area because of its smaller particle size which gives it a high reactivity in some applications.
• GCC: Has a smaller surface area as compared to PCC because of its larger particle size.

Applications:

• PCC: Employed in high-performance applications with specific characteristics such as purity, particle size and shape are critical, like pharmaceuticals, food additives, cosmetics, and high-grade paper products.
• GCC: Used in cases where cost is a major factor, and superior purity and specific properties of PCC are not needed, including construction materials, plastics, rubber, and low-grade paper products.

Specialized Uses:

• PCC: Most suitable in applications which require control of the properties such as in pharmaceutical formulations or premium paper production.
• GCC: More frequently used in applications that do not require such accurate control, and cheap bulk material is suitable for the purpose.

Cost:

• PCC: Practically more costly because of the regulated production and greater purity.
• GCC: Cheap due to the easy-to-produce process and the use of natural materials.

Control Over Properties:

• PCC: Provides exact control over properties such as particle size, shape and purity, which is ideal for applications requiring particular features.
• GCC: The properties of the material are variable and depend on the source material and grinding process as a result of which the final product properties are less easily controlled

Reactivity:

• PCC: In some applications, it is more reactive owing to its increased surface area and properties that can be controlled, which can be beneficial in applications that are associated with chemical reactions or surface coating formulations.
• GCC: Might show less reactivity than PCC because of its larger particle size and variability but it can still be good for many industrial uses.

Filler Material:

• PCC: Regularly employed as a functional additive that improves qualities like whiteness, opacity, gloss, and smoothness in such products as paper, paint, and plastics.
• GCC: Often used as a bulk filler, it provides volume and cuts cost in many industrial applications without changing the characteristics of the final product.
