  • Zircoa Zirconia Powder (Zirconium Oxide, ZrO2) is synthesized from zircon sand (ZrO2 •SiO2) using a solid-state reaction process. Potassium-based geopolymers have been observed to have great thermal stability, mainly due to the crystallization of kalsilite and/or leucite at high temperature as stated by V.F.F. Sakkas et al. Successfully produced a geopolymer based on potassium silicate, and with excellent passive fire-resistant properties and low thermal conductivity. After being exposed to thermal loading with a peak temperature of 1380 °C, the K-based geopolymer specimens showed no damage or visible deformations. X-ray i What is Potassium silicate?The feasibilities of consolidated samples with different potassium silicate solutions (K6, 6, and K5, five mol/L) and different additives (sands, carbonates, and the mix) were tested. All compounds can be easily made and are feasible with homogeneous aspects and the same brown–red color, regardless of their chemical composition, due to the presence of iron in the metakaolin used. A visual inspection of the heat-treated samples shows that every formulation can withstand What is Potassium silicate?The USDA approves potassium silicate as a fertilizer for conventional agriculture. It is used on various crops, including rice, wheat, barley, sugar cane, melons, grapes and ornamentals. Potassium silicate is also used to manage certain fungal diseases on high-value crops. Silicon and potassium are found in nature, but the potassium silicate compound must be manufactured. This doesn't necessarily mean that potassium silicate is inorganic. The compound's function is to What is Zinc Nitride?Zinc Nitride (Zn3N2) Powder is a grey powder with a cubic crystal structure. It is soluble in hydrochloric acid and can decompose at 700℃. Zinc nitride is useful in optical and electronic devices. It is doped with Oxygen to prepare a potential nitride-based transparent conductor used in semiconductors. Zinc nitride can be obtained by thermally decomposing zinc amide (zinc diamine) in an anaerobic environment at temperatures over 200 °C. The by-product of the reaction is amm What is Zinc Nitride?Zinc Nitride (Zn3N2) Powder is a grey powder with a cubic crystal structure. It is soluble in hydrochloric acid and can decompose at 700℃.

The ignition and burning properties of boron can be improved by making boron alloys. This study synthesized an Mg–Al–B alloy from magnesium, aluminum, and boron powders in a 1:1:4 molar ratio by preheating to 600 °C for 30 min, followed by high-temperature sintering in a tube furnace. The effects of sintering temperature (700–1000 °C) and holding time (0.5–10 What is Aluminium magnesium boride?AlMgB14 ceramics were reported as high-hardness materials over a decade ago. While different synthesis routes for processing AlMgB14 ceramics were reported in the past, the synthesis routes are still not optimized and present a significant challenge to the manufacturers. This work explored six different synthesis routes for the synthesis of AlMgB14 powder. The synthesized compositions were characterized by XRD, where weight fractions of each phase were calculat What is CeO2?Nanocrystalline cerium(IV) oxide (CeO2) powders were prepared by heating solutions of cerium(IV) salts in the presence of urea under hydrothermal conditions at 120° to 180°C. The effects of urea concentration and hydrothermal treatment temperature on the morphology and crystallite size of the synthesized particles were investigated. The synthesized particles were angular, ultrafine CeO2 with a cubic fluorite structure. Their crystallite size decreased from 20 to 10 nm with increasin What is vanadium hydride?A vanadium aryl hydride gel was prepared by thermal decomposition and subsequent hydrogenation of tetraphenyl vanadium and evaluated for electrochemical and hydrogen storage performance. Characterization by IR, XRD, XPS, nitrogen adsorption, and TGA suggests that the material consists predominantly of a mixture of vanadium centers in oxidation states of IV bound together by bridging hydride and phenyl groups. Electrochemical properties were explored to probe the reversib
