    Wollastonite (CaSiO3) is a potential biomaterial, particularly beneficial for biomedical purposes such as tissue bone regeneration. The objective of this study is to evaluate the effect of dry and wet milling conditions on the formation of solid wollastonite bioceramic. In this study, synthetic-type wollastonite was produced from chemically synthetic powder; meanwhile, a combination of seashells and rice husk ash (RHA) was used to form natural-type wollastonite. In sample preparation, CaO and SiO2 powder (1:1 weight ratio) were milled together by planetary ball milling operation under different milling conditions: dry and wet milling. The ball-milled powder mixtures were compacted before sintering at 1200°C for 4 hours. The weight loss and shrinkage of the samples were measured and characterized using XRD, FTIR, and SEM analysis. The results confirmed that the wollastonite phase was formed after the sintering process for both dry and wet ball milled processes with anorthic and monoclinic structure types of calcium silicate phases. The wet-milled processed natural powders relatively formed denser bodies and had a higher weight loss percentage compared to dry-milled processed synthetic powders. In conclusion, wet milling is a more suitable method for producing solid wollastonite via powder sintering. In addition, the natural-based sources from RHA and seashells were able to reach the mineralogical properties comparable to synthetic-based sources for forming wollastonite, which could be promising as an alternative material in biomedical applications.

    Paddy leaves can be used to make charcoal briquettes and good as renewable energy sources. The charcoal briquettes were pressed at a pressure range of 50 – 90 bars using the cold press machine. This paper reports the physical and mechanical properties of charcoal briquettes produced from paddy leaves. The moisture content of paddy leaves charcoal briquettes was calculated after dried in an oven at 80°C until the briquettes reached a constant weight. Then, the paddy leaves charcoal briquettes were subjected to the Compression Test with a maximum load capacity of 500kg and crosshead speed of 0.305 mm/min until the briquettes came to a failure as for the investigation of its compressive strength. The average moisture content of paddy leaves charcoal briquettes were in the range of 7-8%. The lowest value of moisture content was 7.32%, recorded by CB5 charcoal briquette sample which, contributed to the highest value of its compressive strength. Its compressive strength was 2.176 MPa. The investigation showed that CB5 was the best charcoal briquette, and the compressive strength was affected by the moisture content in the paddy leaves charcoal briquettes.

    In this study, preparation of porous calcium phosphate was involved the addition of sodium di-hydrogen phosphate, NaH2PO4 and di-sodium hydrogen phosphate, Na2HPO4 into the raw calcium phosphate powder. The sodium hydrogen phosphates salt was act as the porosity agent for the bio-ceramic samples preparation. This method using sodium phosphates salt produced samples with 20-70% porosities. After sintering the sample above 700°C with 4 hours soaking time, results showed that open-pores structure in the range of 1 to 400µm in size were obtained. The pores structure and sizes were depending on the percent addition of the additive and the level of sintering temperature. The compressive strength of porous samples was approximately ranging between 14.38 to 103.42 MPa

    In this work, ternary system (SiO2-CaO-P2O5) biocompatible glass with different compositions (CaO/P2O5 ratio) were prepared by sol-gel method and sintering process. The physical characteristic and bioactive properties of each different sample composition were analyzed using XRF, particle sizer, N2 adsorption-desorption, FTIR, XRD, and FESEM-EDX. The sintered glass pellets were subjected to immersion studies in a simulated body fluid (SBF) solution for 14 days. All compositions of gel-glass particulates showed mesoporous-type structures and consisted of very high porosities with nano-pores in size. Different Ca/P ratios in gel-glass composition are affected by different porous characteristics. All compositions of sintered glass showed very good bioactive behavior by significant deposition of the carbonate apatite layer. Sintered glass with the Ca/P ratio = 2.33 showed very significant bioactive properties as it also comprised the highest pore volume and size. However, sintered glass with the lowest Ca/P ratio (Ca:P=1.50) showed a quite significant reduction in the bioactive property as it also consisted of the lowest pore volume and pore sizes. Hence, the in-vitro bioactivity property of sintered glass is significantly influenced by the increase in its porous characteristics due to differences in the Ca/P ratio.

    Porous bioceramics are the materials of choice for non-load bearing bone implants. Calcium phosphates and bioglass are widely used due to excellent biocompability. The primary function of porous bioceramics are as filler material for bone defects. In this research, 10% amount of sodium bicarbonates (Na2HCO3) were mixed with sol-gel derived glass powder (SiO2-CaO-P2O5) and sintered at 700 C for 3 hours. It was found that, additions of sodium bicarbonate induced a foaming effect during sintering of bioglass thus increased the porosity content of the glass-ceramics obtained. However, the increased in porosity significantly reduced the compressive strength of the crystallized glass. The increased in porosity content and formation of sodium related phases within the crystallized glass matrix after sintering resulted in enhancement of its in vitro bioactivity property when tested in SBF solution.
