Abstract

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 1000oC. 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.
