4.2 Physical Analysis 4.2.1 Density Test
Table 4.1 shows, the samples of undoped calcium phosphate pellets using various sintering temperature. From the experiment, different sintering temperatures are used such as 1000ºC, 1100ºC and 1200ºC. Each sintering temperature have five samples are being used to measure the density of the samples. After analysis, the average density will be collect and recorded. The summary that can get from the table is the mean density for 1000ºC, 1100ºC and 1200ºC sintering temperature is 3.24, 3.26 and 3.25 each respectively.
Based on Table 4.2 shows, the samples of magnesium doped calcium phosphate pellets by using different weight percentage of magnesium pellets without sintering temperature. From the experiment, different weight percentages is used such as 1.0wt.%, 1.5wt.% and 2.0wt.% .Similar with the previous explanation, five samples are being used to measure the density of the samples. The summary that we can get in this table is the mean density for 1.0wt.%, 1.5wt.% and 2.0wt.% weight percentages is 2.75, 2.66 and 2.97 each respectively.
Table 4.3 shows the density test in 1.0wt.%, 1.5wt.% and 2.0wt.% of magnesium doped calcium phosphate pellets at 1000ºC sintering temperature for five samples. The mean density of different concentration are measured based on the average of five samples.

The density of undoped calcium phosphate is 3.24 g/cm3 and highest density for magnesium doped calcium phosphate can be 3.46 g/cm3 for 2.0wt.%. These trends are in increasing pattern where the concentration of magnesium influences the result of density. It means that the sintering temperature can increase the density of the samples. This is because of the pores which are fully filled water will make the density to increase. This result is similar with journal (Matthew J Thompson,
