“…Titanium has received much more attention as a good dental restorative material, because of its excellent characteristics, such as low cost, high strength, being lightweight, having excellent corrosion resistance and biocompatibility [1][2][3]. However, when the fusion temperature is above 800 °C, the Ti surface oxidation will result in a decrease in the bonding strength between the porcelain and Ti, which restricts the application of titanium porcelain [4][5][6]. Therefore, a special titanium body porcelain with low fusion temperature was developed in this research.…”

Titanium body porcelains were synthesised through the sol-gel combustion method by using carbamide and glycine as the composite organic fuels with a mole ratio of 7:3. Then the synthesised porcelain was microwave fused on the Ti surface. The porcelain was characterised by X-ray diffraction and scanning electron microscope tests. The XRD results showed that the body porcelains ignited at 400, 500 and 600 °C were all amorphous. When the ignited temperature is only 400 °C, some crystalline diffraction peaks of KNO 3 existed due to the incomplete combustion reaction. When the igniting temperature was elevated to 500 and 600 °C or a higher ratio of fuel to nitrates (1.25:1 and 1.5:1) was employed, the nitrates completely reacted and there was no obvious nitrate residue. The size and quantity of the pores slightly increased with the ratio of fuel to nitrates increased from 1:1 to 1.5:1. A dense coating with a homogeneous vitreous structure was fused on the Ti surface by microwaves.

Glass-ceramics were synthesized through the sol-gel method. The Thermogravimetry & Differential scanning calorimetry (TG-DSC), X-ray diffraction (XRD), BET, Scanning electron microscope (SEM), bioactivity and turbidometric tests were used to characterize the properties of the glass-ceramics. The TG-DSC results showed that the nitrates could be decomposed completely when the bioactive glass xerogel precursor was heat treated at 750°C. The synthesized glass-ceramic powders had an average particle size of about 3 μm to 20 μm with nanopores on the surface. The XRD results showed that the Na2Ca3Si6O16 and CaSiO3 were the major phases of the glass-ceramics heat treated at 600°C and 700°C, respectively. The flexural strength significantly increased from 79.2 MPa to 163.6 MPa with the sintering temperature increasing from 550°C to 600°C. The formation of carbonated hydroxyapatite can be proved by FT-IR results in this study. The synthesized glass-ceramics have good bioactivity and anti-bacterial property.

“…However, when the temperature is above 800°C, the continual oxidation of titanium results in a significant decrease of bonding strength between Ti–porcelain, which restricts its application [3,4]. A conventional melting-quenching manufacturing process has been used to produce bioactive glass-ceramics powders [5-7]. Compared to the conventional melting-quenching manufacturing process, the glass-ceramics synthesised at much lower temperatures by sol–gel processing has a larger surface area and smaller particle size [4,8], which leads to lower sintering temperature and higher sintering activity [9].…”

The titanium body porcelain was synthesised through sol-gel using borate-silicate system. The porcelain was characterised by X-ray diffraction (XRD), scanning electron microscope and threepoint flexure tests. The XRD and selected area electron diffraction (SAED) results showed that the porcelain was mainly amorphous. The SEM and TEM microphotographs showed that the shape of the porcelain particles was irregular and their sizes range from 5 to 25 μm, while there were no obvious pores on the porcelain surface. The flexure strength significantly increased from 18.9 to 70.6 MPa when the sintering temperature of the porcelain increased from 600 to 675°C and then slowly decreased to 49.1 MPa when the sintering temperature elevated to 700°C. The improvement of the strength was mainly due to the decrease of pores and increase of density. A closely bonded dense coating was fused on the Ti surface by microwave.
