Overview

Gelanggang Kencana Sdn.Bhd. has synthesized and produced numerous zeolites, nanostructured materials and catalysts, including our main innovative product Maerogel (silica aerogel from rice husk), undergoing pilot plant scale and commercialization production. We at Gelanggang Kencana are continuously developing new product processes using indigenous raw and waste organic materials committed to the development on the core R&D areas of synthesis, characterization, and catalysis of microporous zeolites, AlPOS, SAPOS, zeozymes, hybrid catalysts, and mesoporous materials.



Products based on Gel

Silica aerogels are prepared from gels by preparing a colloidal form of the material or Sol, which is called an 'aquasol' if the liquid phase is water and 'alcosol' if the liquid phase is an alcohol. The gels are formed from the sols and if the liquid which permeates the pores is water, the gel is termed an 'aquagel'. If it is an alcohol, the gel is termed an 'alcogel'.

  • Aquagel
      Aquagel or hydrogel from the polymerization of sodium silicate solution.
  • Alcogel
      Alcogel is a gel formed by the coagulation of an alcosol (a sol in which the liquid is alcohol).
  • Maerogel (Silica Aerogel)
      Maerogel or Silica aerogel is a nanostructured material with high specific surface area, high porosity, low dielectric constant, low density and outstanding heat insulation properties.
  • Rensil-A (Renewable Silica Aerogel)
      A silica aerogel with nanostructure with high specific surface area, high porosity, low dielectric constant, low density and outstanding heat insulation properties preparted through ambient pressure drying technique.

  • Rice Husk Products

    Rice husks or hulls are the hard protecting coverings of rice (padi) as coatings of padi seeds, or grains of the padi plant. The husks or hulls are removed from the padi grain containing very high content of amorphous silica (~ 20 wt.%). Rice hulls are an inexpensive byproduct of human food processing, serving as a source of fiber that is considered a filler ingredient in cheap pet foods. Rice hulls are a class A insulating material because they are difficult to burn and less likely to allow moisture to propagate mold or fungi.

    Rice Husks

    Rice husks are the coating for the seeds or grains of the rice plant. The husks are made of hard materials of opaline silica and lignin. The husks contain high content of amorphous silica after combustion and have very valuable properties. Husks are available in large quantity and can be obtained almost free.

    GKSB Rice Husk Ash or Amorphous Silica

    GKSB manufacture rice husk ash (RHA) amorphuos in nature, with a silica content of above 96% with the absence of any pronounce crystalline structure. We produce RHA with very small particle sizes down to 400 nm.

    The RHA can be purified with a silica content of above 99% with the absence of any pronounce crystalline structure. We produce amorphous silica with very small particle sizes down to 200 nm.


    Zeolites

    Zeolites, inorganic crystalline aluminosilicate are non-toxic porous minerals with highly regular structure of pores and chambers possess two intriguing primary physical and chemical properties that are invaluable to the chemical industry (technological & economic) to include molecular sieving, ion exchange dehydration, and rehydration and absorption. Zeolites have many positive ions and absorb a variety of environmental contaminants which can benefit many industries including the hydrocarbon, mining, municipal, commercial, agriculture industries, food, chemical and biotechnology, specialty fine chemicals, refining, and public health.
    There are presently 40 types of natural zeolites with over 160 types of synthetic zeolites but less than 10 commercial zeolites are available. GKSB produces research grade synthetic zeolites which include:-



  • Zeolite A
  • Zeolite P
  • Zeolite Y
  • Other Specialty Zeolites

  • Nanostructured Materials and Catalysis

    Nanotechnology refers to technologies in which matter is manipulated on the atomic and molecular scale (1 nm-100 nm) to create novel materials and processes. It is a study of the very small and the application of that knowledge. Changes in the molecular properties of materials at the nanoscale greatly enhance their physical and chemical properties. In order to benefit from nanotechnology, both scientific and technical challenges must be met. The results of fundamental research in the exploitation of nanotechnology are fabrication, synthesis and design of nanostructured materials with new improved properties. The nanostructured materials are chemical hybrids, microporous and mesoporous materials, solid catalysts, enzyme mimics, aerogels and nanocomposites.


    An exciting new scientific trend emerged in the 80's for exploring zeolites and mesomorphous materials, as advanced solid-state materials. Zeolites and mesomorphous materials or commonly referred as molecular sieves, are porous materials with nanometer dimension (0.3-10 nm) windows, channels and cavity architectures. They represent a 'new frontier' of solid-state chemistry with great opportunities for innovative research and development. The most recent efforts is to find several novel applications which include molecular electronics, "quantum" dots/chains, zeolite electrodes, batteries, nonlinear optical materials, enzyme mimics, chemical sensors, molecular wires and nanodevices.

    The growing interest in these novel systems is due to the bulk behaviour of these nanostructured materials which can be designed and tailored by controlling their cluster nanostructures which lead to greatly improved performance. In addition, the characteristics of these nanomaterials could be purposely engineered by the variation of the chemical composition, structure and size distribution.

    Large pored zeolites, mesomorphous MCM-41, MCM-48 and silica aerogels are naturally nanomaterials due to the existence of pores and crystalline network of nano dimension. Changes in the molecular properties of materials at the nanoscale greatly enhance their physical and chemical properties. Due to its stable and flexible framework of variable sizes, the zeolite lattice may also be used as a host for encapsulated complexes or metallic clusters allowing the control of nuclearity of these active species and the steric contraints imposed on the reactants. MCM-41 and VPI-5, for example, have been used to host polymer, metal complexes and enzymetic species to form molecular wires and zeozymes.

    Mesoporous Products

    Mesomorphous materials are porous materials with nanometer dimension (0.3-10 nm) windows, channels and cavity architectures. They represent a 'new frontier' of solid-state chemistry with great opportunities for innovative research and development.

  • MCM-41

      Mobil Composition Matter is a silicate obtained by a templating mechanism displaying honeycomb-like structures where the width of the channels can be controlled to be within 2 to 10 nm with uniform mesopores and large surface areas used for catalysis. MCM-41 has a hexagonal crystal structure with a uni-dimensional pore system.

  • MCM-48

      MCM-48 has a cubic symmetrical structure with a 3-dimensional pore system having two independent intertwined channel networks. MCM-48 is an attractive candidate for use in various sorption and catalysis applications.
