• Method of preparing controlled release fertilizers and products thereof
  申请人：Nutrihold Inc.

  公开号：US05030267A1

  公开（公告）日：1991-07-09

  Controlled release fertilizers containing water-soluble nutrients such as potassium nitrate which are easily leached from the fertilizer by moisture in the soil have a coating which more efficiently retards the release of the nutrients and also provides citric acid soluble silicon to the soil. Nutrient particles are first coated wtih a colloid formed by the acidification of preconditioned calcium metasilicate with citric acid and then mixed with cement. The calcium metasilicate is preconditioned by heating to a temperature of at least 1300.degree. C. to sinter at least a portion of the silicate. The nutrient particles are then pelletized and cured to form a silica gel matrix containing acicular calcium metasilicate and a cement coating on the pellets. The nutrient pellets may be mixed with cement coated urea prills in a silica gel formed by the acidification of preconditioned calcium metasilicate with nitric acid to further retard the release of nutrients, and to provide additional citric acid soluble silicon as well as nitrogen to the fertilizer. In addition a phosphorus source such as a municipal sludge may be added to the silica gel.

  含有易被土壤中的水分淋失的水溶性营养元素（如硝酸钾）的控释肥料，其涂层更有效地延缓了营养元素的释放，并向土壤提供柠檬酸可溶性硅。首先，将营养颗粒涂上由预处理的硅酸钙硅酸化而形成的胶体，然后与水泥混合。硅酸钙通过加热至至少1300℃的温度烧结至少一部分硅酸盐来进行预处理。然后将营养颗粒制成颗粒状并进行固化，形成含有针状硅酸钙硅胶基质和颗粒的水泥涂层。营养颗粒可以与涂有水泥的尿素颗粒混合在一起，形成硅酸钙硅胶，以进一步延缓营养元素的释放，并为肥料提供额外的柠檬酸可溶性硅和氮。此外，还可以添加磷源，如市政污泥到硅酸钙硅胶中。

  Abstract The dispersed Ca3La6(SiO4)6 biocomposite was obtained by treating a calcium silicate sol containing 0.1, 0.3, and 0.7 mol of La3+ under hydrothermal conditions. The composition, morphology, and structure of the biocomposite were studied by powder X-ray diffraction, SEM, and EDS methods. The reaction products (CaSiO3, CaLa4(SiO4)3O, Ca3La6(SiO4)6) depending on the La3+ concentration were determined

• Mimosa pudica mediated praseodymium substituted calcium silicate nanostructures for white LED application

  In this paper a simple green route was adopted for the synthesis of orange light emitting CaSiO3:Pr3+ (1-11 mol %) phosphors using Mimosa pudica L. extract as a fuel. The final product was well characterized by powder X-ray diffraction (PXRD), Fourier transform infra-red spectroscopy, diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM) and transmission electron microscopy. The concentration of plant extract plays an important role in controlling the morphology as well as the formation of superstructures. The obtained superstructures from SEM studies resembled the naturally existing structures like dates, cactus, coconut shell, etc. The energy band gap estimated using DRS was found to be in the range of 5.23-5.47 eV. The emission peaks at 550, 606, 650 and 733 nm were due to the transitions of P-3(0) -> H-3(4, 5), F-3(2, 3). The Commission International de I 'Eclairage and colour correlated temperature coordinates were estimated for all the concentrations of Pr3+ ions and the results indicates that the phosphor may be quite useful in cool light source. The crystalline nature and phase was confirmed by PXRD for the calcined samples at 950 degrees C for 3 h. This was the lowest formation temperature reported in the literature for Pr3+ doped CaSiO3. FTIR results showed the stretching vibrations of Si-O at 720 cm(-1), asymmetric stretching vibrations of Si-O-Si bonds at 560 cm(-1). The present preparation method was simple, eco-friendly, inexpensive and free from unwanted by-products which can be used for large scale production. (C) 2016 Elsevier B.V. All rights reserved.
