The delay in license renewal was due to a series of changes in the licensing process, requirements and personnel. The Company does not anticipate any further delays in licensing and intends to apply for the IML A license shortly which will allow high volume production and sales. Graphite mining and removal of material via the mine shaft will re-commence immediately, with separation of high-grade graphite taking place on site. Construction of an incline tunnel will begin shortly which will allow for rail access via a 200m tunnel, significantly increasing the volume of material which can be moved daily. The Company intends to complete two exploration chambers underground to allow for horizontal drilling to further optimize production. M1 graphite is consistently above 90% carbon allowing for direct sales without further processing. The Company anticipates building a graphite processing plant at the M1site to process the graphite to 99%+. The in-country team has built such a plant previously in Sri Lanka and expects increased revenue potential from the 99%+ material, once processed.공시 • Nov 28Ceylon Graphite Corp., Annual General Meeting, Jan 31, 2024Ceylon Graphite Corp., Annual General Meeting, Jan 31, 2024.공시 • Oct 28Ceylon Graphite Corp. announced that it has received CAD 0.365 million in fundingCeylon Graphite Corp. announced a non-brokered private placement that it has issued 9% senior secured convertible debenture units of the company for the gross proceeds of CAD 365,000 on October 27, 2023.

Achieves New Concentration and Conductivity Records When Studied in the Manufacture of an Adaptable Sensing Platform for Chemical SensingCeylon Graphite Corp. announced that Ceylon graphite achieved new concentration and conductivity records when studied in the manufacture of an adaptable sensing platform for chemical sensing. The research, published in the Royal Society of Chemistry's "Nanoscale" Journal, was conducted by partners at the Molecular Sciences Research Hub at Imperial College London and specifically incorporated Ceylon's vein graphite to produce a low-surface-tension sprayable graphene ink that was key to the sensor's functionality. A summary of the test results, completed in January 2023 is highlighted: Ceylon graphite was used to create high concentration, graphene/polyvinylpyrrolidone inks, with record-breaking concentrations as high 3.2 mg mL-1. Raman spectroscopy was used to show high-quality graphene flakes produced via liquid phase exfoliation. The Ceylon-based graphene device was successfully used to detect for pH within the range of pH 3 - 11. These results demonstrate the potential of high-quality graphite to empower the next generation of nano-based diagnostics for biological and chemical sensing. Results in Summary: Graphene ink formulation: Graphene inks have emerged as a new revolutionary element for high-performance printed, flexible and wearable electronics. Among the various methods available for preparing graphene ink, sonication-assisted liquid-phase exfoliation (LPE) has been chosen due to its simplicity and compatibility with low-boiling solvents. This process involves subjecting graphite (in powder or flakes) and low-boiling point solvents, such as 2-propanol (IPA), along with small amounts (20 mg) of the polymer stabiliser, resulting in a graphene ink with desired electronic propertied for printed electronics and significantly enhanced shelf life of the ink. IPA was selected as the solvent for the graphene ink as it has a boiling point of 82 degC and impressively low surface pressure of only 20.34 mN m-1, satisfying the criteria for a scalable spray-coating as well as inkjet printing of the optimised ink. The sonication process lasts for 9 hours, ensuring thorough exfoliation of the graphite flakes. Centrifugation at 2.000 - 13,000 g is then employed to further refine the ink and effectively eliminate any remaining unexfoliated flakes. The optical absorption spectrum (OAS) of the graphene ink, exhibits the characteristic profile associated with the profile associated with the potential of graphene flakes. The optical absorption spectrum (OAS) of the graphene ink exhibits the characteristic profile associated with graphene inks, a flat absorption pattern in the visible spectrum and a distinctive peak in the UV region, confirms the ink is mainly composed by high-quality graphene flakes. The concentration of graphene flakes in the ink is estimated to be ~ 1 mg mL-1 when centrifuged at 13,000 g and as high as 3.2 mg mL-1 when centrifuged at 2,300 g. This concentration surpasses those reported in the literature for graphene inks stabilised by polyvinylpyrrolidone (PVP) by an order of magnitude, underscoring the exceptional quality and potential of this formulation. Application: A graphene field-effect transistor as a scalable and low-cost high-performance biosensor. The EG-GFET channel is formed using an automatic spray-coating process, ensuring consistent and scalable deposition of the graphene ink onto the PCB test strip. The graphene ink exhibits excellent wetting properties that contribute to film uniformity. As the individual ink droplets merge into a thin film before evaporating, this wetting behaviour plays a vital role in achieving uniformity. While the addition of PVP stabilizer enhances the concentration and stability of the ink, it is important to note that PVP is known to adversely affect the electrical conductivity of nanostructured graphene thin films due to its insulating properties. However, a solution has been found by utilizing a xenon intense pulsed light (IPL) source, which effectively degrades the PVP polymer without subjecting the PCB substrate to temperatures exceeding its decomposition threshold. This method proves to be the most suitable for this specific application. The spray coated graphene ink achieved an approximate channel resistivity of 100 O after IPL annealing suitable for flexible and plastic electronics and currently used in industry.더 많은 업데이트 보기Recent updates공시 • May 01Ceylon Graphite Announces M1 License Renewed Allowing for Recommencement of Mining ActivitiesCeylon Graphite Corp. announced that its IML C license at its M1 mine has been renewed.

The EG-GFET channel is formed using an automatic spray-coating process, ensuring consistent and scalable deposition of the graphene ink onto the PCB test strip. The graphene ink exhibits excellent wetting properties that contribute to film uniformity. As the individual ink droplets merge into a thin film before evaporating, this wetting behaviour plays a vital role in achieving uniformity. While the addition of PVP stabilizer enhances the concentration and stability of the ink, it is important to note that PVP is known to adversely affect the electrical conductivity of nanostructured graphene thin films due to its insulating properties. However, a solution has been found by utilizing a xenon intense pulsed light (IPL) source, which effectively degrades the PVP polymer without subjecting the PCB substrate to temperatures exceeding its decomposition threshold. This method proves to be the most suitable for this specific application. The spray coated graphene ink achieved an approximate channel resistivity of 100 O after IPL annealing suitable for flexible and plastic electronics and currently used in industry.
