A spinning disk reactor (SDR) was applied and tested successfully for precipitated calcium carbonate particles synthesis in liquid–liquid system which is poorly understood in literature. The proposed SDR reactor consists of a spinning disk rotating at 4000–16,000 rpm. The proposed SDR resulted in a high local supersaturation ratio due …

Calcium carbonate (CaCO3) is the most widely used filler material in paper, paint, plastic, food, ceramic, cosmetic, medicine and other industries. In the present paper, precipitated calcium ...

Carboxymethyl cellulose and alum were used in the modification of precipitated calcium carbonate filler, and the use of modified fillers in papermaking was investigated. The alum dosage was found to be much critical to the effective precipitation and encapsulation of carboxymethyl cellulose on filler surfaces.

The efficiency of powder blend homogeneity in low-dose DPI preparations using the Alphie 3D Tumbler Mixer. Calcium carbonate derived from mixing in Alphie 3D Mixer, forming a product grade of …

Precipitated calcium carbonate (PCC) is conventionally produced through the gas–solid–liquid carbonation route, which consists on bubbling gaseous CO 2 through a concentrated calcium hydroxide (Ca (OH) 2) slurry. However, atmospheric carbonation processes are slow and have low carbonation efficiency.

Imerys combines high-quality feed materials, state of the art processing techniques and in-depth market knowledge to generate a broad portfolio of ground calcium carbonate (GCC) and precipitated calcium carbonate (PCC) products to serve construction, paper, paint, plastics, rubber, adhesives, food and pharmaceuticals, agriculture and industry.

The Machine Learning ( ML )-based models presented in this study provide engineers with a fruitful framework for the rough and preliminary estimation of the amount of calcite precipitation as well as the UCS of bio-mediated sands in the field prior to stabilization and performing complementary tests.

ABSTRACT The study presented a powder processing method involving calcination and subsequent carbonation in the synthesis of precipitated calcium carbonate (PCC) for recycling green mussel shells, which contain a high calcium carbonate content. The purity of portlandite [Ca(OH)2] as a result of calcination and subsequent moisture absorption …

The experimental results show that both the calcium carbonate slurries produced with the studied concept are easy to filter with pressure filtration and with …

The transformation of CO2 into a precipitated mineral carbonate through an ex situ mineral carbonation route is considered a promising option for carbon capt...

Alternatively, calcium carbonate can be produced from calcium oxide. This involves adding water to create calcium hydroxide, followed by the passage of carbon dioxide through the solution to cause the precipitation of calcium carbonate. This resulting form is known as precipitated calcium carbonate (PCC).

This research primarily focuses on the feasibility of substituting imported calcium carbonate fillers with locally available materials for PVC pipe applications.

PCC are coated with a low percentage (1-3 percent) of a fatty acid, such as Stearic acid, for use in non-aqueous systems

A series of experimental precipitated calcium carbonates (PCCs) coated with commercial stearic acid (stearin), with the coating amount of stearin added to the PCC particles ranging from 3 to 13.5 ...

A revolution in wood-free papermaking has occurred over the past decade. 1 The availability of low-cost precipitated calcium carbonate (PCC), manufactured on individual paper mill sites, fueled the rapid expansion of alkaline papermaking. PCC provides many benefits, including excellent brightness and opacity at significantly lower cost than the …

The brightness and opacity of handsheets filled with modified precipitated calcium carbonate were markedly improved in comparison to the control. Furthermore, handsheets filled with modified precipitated calcium carbonate reduced the loss of tensile strength compared to the control at the same precipitated calcium carbonate content.

Abstract: Calcium carbonate (CaCO3) is the most widely used filler material in paper, paint, plastic, food, ceramic, cosmetic, medicine and other industries. In the present paper, precipitated calcium carbonate (PCC) has been produced from waste marble powder (WMP) by the Calcination-Dissolution-Precipitation (CDP) method.
