Silicon Nitride (Si3N4) has good high temperature strength, creep resistance and oxidation resistance. In addition, its low thermal expansion coefficient gives good thermal shock resistance compared with most ceramic materials. Silicon nitride is produced in two main ways; Reaction bonded silicon nitride (RBSN), and hot pressed silicon nitride (HPSN) and sintered silicon nitride (SSN). RBSN is made by direct reacting compacted silicon powder with nitrogen, and produces a relatively low-density product compared with hot pressed and sintered silicon nitride, however the process has only a small volume change allowing net shape forming. The HPSN and SSN material is made with sintering aids and offers better physical properties suitable for more demanding applications. Typical Silicon Nitride applications include: Bearing balls and rollers Cutting tools Valves, turbocharger rotors for engines Turbine blades Glow plugs Molten metal handling Thermocouple sheaths Welding jigs and fixtures Welding nozzles Advantages 1.High hardness 2.Wear resistance 3.High fire resistance 4.Corrosion preventive 5.Good chemical stability

Super Silicon Voga are natural silicon rich minerals that contain high amount of active silicon and other beneficial nutrients. Super Silicon Voga contains over 5,000 ppm of plant available silicon, 20 times higher than other brands. Silicon is known to be absorbed by plants and transported to plants' cell walls. It helps strengthen cell walls, as a result, more tolerance of pests and diseases. It also has high cation exchange capacity (CEC) which helps improve soil�¢??s physical and chemical structure and soil's capacity to retain nutrients and slowly release them to plant's roots.�?� In soils, it helps loosen up hard soils resulting in better root growth.�?� Not only preventing loss of nutrients,�?� it also makes them more readily available to plants. Silicon also helps release fixed phosphate from soils resulting in better flowering. Silicon accumulated on leaves make them more shiny and help reduce transpiration rate. It can reduce water usage by as much as 30% resulting in more drought tolerant. Produce with silicon will taste better and stay fresh for longer time. Super Silicon Voga can be used in a variety of ways. Mix with chemical fertilizers, it will help prevent loss of nutrients and provide source of silicon to plants. Mix when spaying fungicides or insecticides, it will enhance and prolong the substance's efficacy. It can also be used to cure fungal diseases on trunks. Benefits: - Enhance efficacy of chemical fertilizers, prevent leaching - Prevent fungal and other diseases - Strengthen plants, improve resistance against pests and diseases - Enhance efficacy of chemical fungicides and pesticides�?� - Absorb toxins from soils, fruits, and vegetables Usage: - Mix with chemical fertilizer, manure or organic fertilizer before applying to soils. Use 1 kg of Super Voga for 50 kg of fertilizers. - Mix with small amount of water to make paste. Apply paste on plant's trunk infected by fungi. - Spread small amount around canopy to prevent root rot. - Mix 1 teaspoon of Super Voga in 20 liter spraying tank when spray fungicides or pesticides to increase their effectiveness - Mix 1 teaspoon Super Voga in 5 liter water. Use it to clean vegetables or fruits to clean chemical residues and help prolong freshness.
