25 NOV 2021 · Silicon Nitride is a man-made nonmetallic compound that is usually in dark grey color and can be polished to create a reflective surface. The material has various industrial applications nowadays due to its improvement throughout the year. The production of silicon nitride involves well-developed methods and each method’s end result depends on the method. 1. Reaction-bonded Silicon Nitride (RBSN) The heating of compact silicon powder in a nitrogen gas atmosphere makes reaction-bonded silicon nitride. This material hardening process undergoes at 1450° called nitriding. The material has the key properties of capacity to be framed into complex shapes easily. The cost-effective porous material has various applications like nozzles. 2. Hot Pressed Silicon Nitride The hot pressing of silicon nitride makes nearly zero porosity and exceptional strength shows good resistance to thermal shock and good thermal conductivity. 3. Sintered reaction-bonded Silicon Nitride (SRBSN) SRBSN which is an upgraded version has reduced porosity. The process requires a long nitriding time at a temperature of more than 1800° and have shown improvements to impact resistance and toughness. 4. Sintered Silicon Nitride (SSN) The process occurs at the pressure less sintering at 1750° with additives such as aluminium oxide and magnesium oxide in a nitrogen atmosphere to aid densification. SSN offers the best mechanical properties. Applications of Silicon Nitride Due to its outstanding chemical-physical properties and, it has various applications in chemical, metallurgy, and machinery industries. It is used in making cutting tools and sprays pipes for missiles. As its bearing rollers can withstand high stress, silicon nitride is used in automotive engine parts. Silicon nitride has also been used in high-temperature applications. --- Send in a voice message: https://anchor.fm/multi-lab/message

17 SEP 2021 · Fracking is a general or slang term used for hydraulic fracturing. Hydraulic fracturing requires digging into the ground to get energy-rich natural gases from under the shale rock. Frac sand is a unique form of sand because it is much rounder, tougher and permeable. The rounded form of the sand granules enables the water and gases to move through. It limits the clogging of the hole and lets the cracks keep open while still allowing the gases to move around. This feature of the frac sand makes it unique from other materials. This material is important to ensure the pure and natural gas result in the extraction process and there will be no contaminants or foreign figures that could be hiding. More developed sand that is almost quartz is the ideal kind of frac sand and this should be properly rounded. More fresh sand usually has a more visible or angular appearance and they often bring several minerals and rock particles. Excellent attribute frac sand is effortless to clean and separate from other elements, making it more comfortable to eliminate the particles and mud. The sand experiences various processes to eliminate any contaminants, to separate the sand by the measurement of all units and the quality of the textures. It must hold a form that is similar to brown sugar. Frac sand drilling is a really effective application. With the aid of sand mining, there can be more projects and it could help enhance the economy of the areas. By using high-quality sand, it is likely to satisfy the requirements for natural gas as a kind of fresh fuel and it can better support the industry. Uses of Frac Sand: - High-quality Frac Sands need to pass a crush examination because of the high volumes of force it has to endure. The quartz sand is remarkably pure and reliable. The more powerful the crush circumstance, the more reliable the sand. Also, the more powerful the cleanliness and crush factor, the more valuable the product. There are many different things that industries look for in the high standard and high crush frac sand. Take a look: It should be a high-quality quartz silica sand It needs to be the proper texture size for a hydraulic fracturing work It should be round in shape It is ready to withstand the crushing capabilities of the neighbouring shale rock. Since the fracking industry has evolved, so demand for nearby sourced frac sand is also increasing. Hence, alternative ceramic and alloy particles have started to replace expensive, high-end sands. --- Send in a voice message: https://anchor.fm/multi-lab/message
