“…The most prominent characteristic of mica is nearly a perfect basal cleavage. Wollastonite is a calcium silicate (CaSiO 3 ) industrial mineral, which is commonly used as a filler in paints and plastics [33,34]. It is also used in the construction industry as a substitute for asbestos; ceramic applications including ceramic glazes and bodies; in metallurgical applications wollastonite is commonly added to formulated powders for steel casting and welding.…”

“…Synthesized calcium silicate from the composition of natural silica with natural carbonates from quartz sand and limestone has been done by researcher [6]. The study used a solid reaction method with a calcination temperature of 1100 o C. The study results indicated that calcium silicate appears at temperatures of 850 o C and 1100 o C. While another researcher [7] conducted a study of the synthesis and characterization of calcium silicate, the results of the study showed that the microstructure of natural calcium silicate after calcination at 850 o C had different chemical phases and compositions. After 900 o C calcination, the phase composition of the composting process and crystallization increases.…”

This research aims to utilize blood cockle shell waste and silica sand as a new innovation in the manufacture of calcium silicate minerals which were used as fillers in paper making industry. In this study the manufacture of calcium silicate mineral fillers (CaSiO3) used solid state reaction technique at a temperature of 1000 o C. Some researchers have tested the use of blood cockle shells as the raw materials for making calcium silicate, so further research was needed to find out whether the calcium silicate produced can be used in paper making. Sample characterization was carried out with Fourier Transform Infrared (FTIR), Keyence microscopy and X-Ray Diffraction (XRD). The results showed that the calcium silicate phase contained the wollastonite-1A phase (CaSiO3) with the highest intensity peak at an angle of 2θ = 26.8225. FTIR analysis also showed the structure of calcium silicate with the formation of Si-O-Si and O-Si-O functional groups at a wavelength of 460 cm-1 , Si-O-Ca at a wavelength of 962 cm-1 and O-Si-O cm-1 at a wavelength of 901 cm-1. The microstructure analysis using Keyence microscope showed that the sample granules were globular in shape with a particle size of approximately 14 µm. From all the paper testing results consist of brightness, bulk density, tearing, bursting, tensile and folding endurance showed that calcium silicate filler has fulfill the TAPPI International standard.

“…According to Demidenko [12], the characterization of calcium silicate ceramics using scanning electron microscopy (SEM) techniques sintered at temperatures of 850 o C to 1100 o C reveals that the microstructure of calcium silicate ceramics is going better at sintering temperatures of 1100 o C with a density of 2.32 g/cm 3 , and porosity of 27.5%.…”

This research aimed at developing a method of glaze material making from used glass bottle waste combined with kaolin. Then, the microstructure and hardness level of glaze products were characterized. Furnace heaters were used in research to heat glaze material by varying the holding time of 30, 45 and 60 minutes. The composition of glaze material was varied with the ratio between glass and kaolin of 70:30, 80:20 and 90:10. The results revealed that the process of glaze material making was successfully carried out. The results of the hardness test showed that at the 30 minutes holding time, the hardness was 82.53 VHN. The hardness value increased when the holding time was 45 minutes with an average hardness value of 85.03 VHN. The highest average hardness obtained when the variation of 60 minutes holding time was 87.6 VHN. The difference in hardness value in variation possibly occurred because of the differences in the distribution of amorphous solids, porosity, and pinhole which was influenced by the differences in glass and kaolin composition.
