Feasible calcium carbonate polymorphs synthesis from natural corallines and their potential gelling role in hydraulic fracturing application

Abstract

Hydraulic fracturing fluids are significantly important for petroleum and related industrial areas in the preceding and forth-coming eras. In this work, we have feasibly synthesized the calcium carbonate polymorphs from the natural coralline limestones through a chemical precipitation process. The apparent physical morphology of the structure revealed the co-existence of the aragonite, vaterite, and calcite within the structure while the aragonite is the major component throughout the structure. The X-ray diffraction and Zeta sizer showed a nominal particle size of 23 nm of the structure which is well-matched with the prior reports. The acquired polymorphs have been functioned for the preparation of the gelling agent. The physicochemical characteristics of the agent were implemented in the materials safety data sheet of the product. The Gelling agent in the report is compared to familiar agents based on Xantham gum which reflects much less cost as well as the proposed potential application in the medical and petroleum industry.
