Trace amounts of silicon (Si) are essential for healthy bones, ligaments and skin as well as cellular health and collagen/elastin regeneration.
Switching from black SiC to green SiC can reduce emissions in solar panels significantly; however, customer attitudes regarding switching can differ dramatically between industries.
Green silicon carbide
Green silicon carbide is an extremely hard, robust material made by man that finds many uses across industries. Produced from silica quartz sand and petroleum coke that are electrofused together in an arc furnace to form sharp blocky grains with Mohs 9.4 hardness (approx. 2600 Knoop hardness), strong cutting capacity, stable chemical properties and elevated strength at elevated temperatures – it even resists corrosion! Common applications for green silicon carbide include grinding/abrasive applications including cutting metals/ceramics/glass.
Silicon carbide powder can also be sinter-bonded with cemented carbide to form superhard materials for various uses, including car brakes and clutches, bulletproof vest ceramic plates and bulletproof vest ceramic plates. Furthermore, silicon is also an integral component in high performance cookware fluorocoatings; produced as both black and green powder varieties with the latter representing higher purity silicon levels than its black counterpart.
GNPGraystar’s submicron Green Silicon Carbide is processed to achieve specific surface areas and purities for technical and structural ceramics, essential in sintering processes that influence dramatically their mechanical properties. Quick quality control tests using real time transmission X-ray radiographic imaging provide quick quality checks. This technique allows detection of defects within sinter and provides information regarding their size, volume, location, as well as information regarding any related manufacturing problems.
Green silicon oxide
Green silicon oxide is a naturally-occurring mineral with numerous applications. It can be found in glass, ceramics and refractories production as well as industrial processes requiring heat resistance such as coatings and paints. Green silicon oxide also serves as an excellent insulator and corrosion inhibiting material, and plays an integral part in semiconductor applications. Through our technology we eliminate direct carbon dioxide emissions while drastically decreasing energy requirements by up to 95% during silicon production – saving both operational costs and fossil-based electricity import costs while outcompeting traditional methods both cost effectively and sustainably.
IR absorption spectroscopy was employed to investigate the kinetics of self-assembly of APTES on chemically grown silicon oxide (SiO2). Our findings indicated that formation of an APS film depends on parameters like temperature and oxygen concentration; furthermore, this technique provided insights into Si-H bonding within Si-O-Si systems.
Silicon is an inorganic element, typically white in colour with little solubility in water. It is found in various minerals including diatomaceous earth – mined product made up of the shells of microscopic algae – used as food preparation aid to decrease foaming and caking of powdered food products and clarify liquids. Silicon can also be found as components in silicone rubber compounds and inorganic glass compounds; although small amounts are essential to health, too much silicon exposure could lead to osteoarthritis or joint problems.
Green silicon nitrate
Silicon nitride is an electronic ceramic material with many applications in the electronics industry, such as semiconductors, solar cells, and fuel cells. This ceramic has excellent creep resistance, high temperature strength, oxidation resistance and thermal shock resistance – qualities which make it highly sought-after by electronics engineers. Producing silicon nitride typically involves nitriding silicon powder compacts; however, this requires expensive equipment and produces significant quantities of oxides; managing temperature control can be problematic; however a breakthrough in technology could change all this – all this.
Quartz and hydrogen are the key raw materials for green silicon nitrate production, while the company is looking for sites with reliable renewable electricity to power its process. Furthermore, the startup aims to develop a low-emissions silicon production process that reduces carbon dioxide emissions while simultaneously replacing energy-intensive methods with simpler energy-saving ones; additionally, this method will eliminate expensive electric arc furnaces or Siemens refining processes as required in conventional production lines.
Nitriding can be conducted using various techniques. One popular one involves mixing nitrogen and hydrogen gas together in an atmosphere, with temperature controlled by adding more gas into the system. This new approach produces far fewer volatile oxides than traditional processes, is much more sustainable, significantly cheaper and can even produce silicon nitrate as a precursor for numerous products; KTH Royal Institute of Technology in Stockholm hosts this pilot plant that can produce five kilogrammes per hour of silicon.
Green silicon sulfate
Silicon is an essential mineral, used to strengthen bones. It promotes bone formation and increases density. Men and younger (pre-menopausal) women who consume more silicon from food seem to experience greater bone strength; however, its effect does not seem to extend to older (postmenopausal) women whose bodies break down bone rather than build new ones. Furthermore, evidence exists for using silicon to treat osteoporosis; its safety in medicine doses remains undetermined; silicon may cause rare side effects including shortness of breath, irritability and dry cough in certain individuals.
GREEN14’s plasma technology makes it possible to decarbonise and reshore silicon production for solar, semiconductors, and batteries in Europe and the US by up to 95%, using renewable electricity as power and minimising carbon footprint. Furthermore, its recycling of solar wafers and silicon kerf from previous production processes further reduces environmental impacts.
Customers in the solar panel industry tend to be most attracted to green silicon due to its ability to reduce embodied emissions significantly and improve transparency and secure supply chains, respectively. Conversely, customers in computing industries may see reduced benefits from switching over because green silicon only accounts for approximately 8-9% of total emissions associated with final products.
