| Hardness of | 65 | 62 | 70 | 73 | 79 | 84 | 77 | 70 |
According to the contents of tables 1 and 2, it can be seen that the hardness value in the test results obtained from samples 3-6 prepared from 45-55 parts of the oolong tea spar A material, 15-25 parts of the Longyan soil, 5-10 parts of the raw ore Longyan soil, 15-25 parts of quartz, 5-10 parts of ball soil, 5-10 parts of temple soil, 75-80 parts of water, 10-20 parts of polycarbonate and 15-25 parts of nano titanium dioxide is gradually increased to reach the highest strength, so that the hardness of the high-silicon functional porcelain prepared from the material and the components thereof is enhanced, and the high-silicon functional porcelain has the advantage of higher hardness.
(2) Light transmittance test
The testing steps are as follows:
samples 1-8 in Table one above were placed in the spectrometer, respectively, in sequence, and transmittance data over the wavelength range was recorded for each sample, see Table 3.
Table 3: estimated transmittance data (%)
| Wavelength (nm) | Sample 1 | Sample 2 | Sample 3 | Sample 4 | Sample 5 | Sample 6 | Sample 7 | Sample 8 |
| 400 | 30 | 33 | 35 | 38 | 40 | 28 | 25 | 22 |
| 500 | 40 | 42 | 45 | 48 | 50 | 37 | 33 | 30 |

In sample 3, 35% of the light transmitted through the sample at a wavelength of 400, and the transmittance increased to 60% as the wavelength increased to 700 nm; in sample 4, 38% of the light transmitted through the sample at a wavelength of 400, and the transmittance increased to 63% as the wavelength increased to 700 nm; in sample 4, at a wavelength of 400, 40% of the light transmitted through the sample, and as the wavelength increased to 700nm, the transmittance increased to 65%. This means that as the wavelength increases, the transmittance increases, and thus the surface samples 3 to 6 have a stronger light transmittance.
(3) Thermal shock resistance test
The thermal shock resistance of ceramic materials depends on two factors, one is that the strength itself is the magnitude of thermal expansion and contraction (i.e., thermal expansion rate). The former is the intrinsic properties of the material itself, and the latter is the change caused by the change in external conditions. The blanks prepared by the materials in the compositions shown in Table 1 are prepared into test strips with the thickness of 5mm and the thickness of 50mm according to the respective sintering temperatures, and then the respective thermal expansion coefficients are tested, and the results are shown in Table 4.
TABLE 4 thermal shock resistance coefficient table
| Sample sintering temperature (. Degree. C.) | 1220 | 1225 | 1230 | 1235 | 1240 | 1245 | 1250 |
| Sample 1 | 4.8 | 4.9 | 5.0 | 5.1 | 5.2 | 5.3 | 5.4 |
| Sample 2 | 5.0 | 5.1 | 5.2 | 5.3 | 5.4 | 5.5 | 5.6 |
| Sample 3 | 4.0 | 4.1 | 4.2 | 4.3 | 4.4 | 4.5 | 4.6 |
| Sample 4 | 4.2 | 4.35 | 4.5 | 4.65 | 4.8 | 4.95 | 5.1 |
| Sample 5 | 4.4 | 4.6 | 4.8 | 5.0 | 5.2 | 5.4 | 5.6 |
| Sample 6 | 4.5 | 4.6 | 4.7 | 4.8 | 3.9 | 5.0 | 5.1 |
| Sample 7 | 5.5 | 5.6 | 5.7 | 5.8 | 5.9 | 6.0 | 6.1 |
| Sample 8 | 6.0 | 6.1 | 6.2 | 6.3 | 6.4 | 6.5 | 6.6 |
As can be seen from the thermal expansion coefficient test in Table 4, the overall thermal expansion coefficient of samples 3 to 6 is lower than that of samples 1 to 2 and 7 to 8, and thus it can be seen that the thermal expansion coefficient of the high silicon functional porcelain prepared from 45 to 55 parts of the oolong tea spar A material, 15 to 25 parts of the Longyan soil, 5 to 10 parts of the raw mineral Longyan soil, 15 to 25 parts of quartz, 5 to 10 parts of the ball soil, 5 to 10 parts of the temple soil, 75 to 80 parts of water, 10 to 20 parts of polycarbonate and 15 to 25 parts of nano titanium dioxide is slightly lower, which indicates that the high silicon functional porcelain prepared from the components has excellent thermal shock resistance.

b. The type of each simulated stain and the amount of smeared was recorded.
c. The two materials were cleaned using standard cleaning methods and cleaners, and the cleaning time and cleaning effect during the cleaning process were recorded.
d. The cleaned sample surfaces were observed and compared using a visible spectrometer and the data recorded, see table 5.
Table 5: high silicon porcelain stain cleaning effect comparison data sheet
| Experimental group | Stain type | Application amount | Time of cleaning | Cleaning effect | Visible spectrum observation data |
| A | Oil stain | Medium and medium | For 10 minutes | Clean completely | No change |
| A | Pigment | A little | 15 minutes | Part of the residues | Pico residual |
| A | Coffee stain | A large number of | 20 minutes | Cleaning of | Picodiscoloration |
| B | Oil stain | Medium and medium | For 12 minutes | Part of the residues | Pico residual |
| B | Pigment | A little | 18 minutes | Difficult to clean | Obvious residue |
| B | Coffee stain | A large number of | 25 minutes | Difficult to clean | Obvious color change |
As shown in the above table, there is a certain difference between the test group a and the test group B in different material types, but as a whole, the stains on the surface of the test group a are easier to clean, and the cleaning time is relatively short, which indicates that the high-silicon porcelain sample of the test group a has a faster cleaning property.
3. Antibacterial property test
Two high-silicon porcelain are selected as sample materials, and one high-silicon porcelain prepared by adopting the material is used as an experimental group A; another high silicon porcelain prepared from conventional materials was used as experimental group B to ensure that the samples were identical in size and shape for comparative testing. And selecting common bacterial species such as E.coli and Staphylococcus aureus, and culturing the bacteria on a suitable medium. The cultured bacterial suspension is uniformly smeared on the surfaces of samples of the experimental group A and the experimental group B, so that each sample is ensured to be inoculated with the same amount of bacteria. The inoculated samples were incubated under constant temperature and humidity for 24 hours. After incubation, samples were taken from the sample surface and the bacterial count was counted using plate counting to assess bacterial growth on the different sample surfaces. The bacterial count results were recorded and statistically analyzed to compare the inhibition ability of the samples in experimental group a and experimental group B against bacteria, as shown in table 6.
TABLE 6 bacterial count
| Sample type | Bacterial species | Average bacterial count (CFU/cm) |
| Experimental group A | Coli bacterium | 1200 |
| Experimental group A | Staphylococcus aureus | 900 |
| Experiment group B | Coli bacterium | 3000 |
| Experiment group B | Staphylococcus aureus | 2500 |
As shown in Table 6, the high silicon porcelain prepared by the material of the present invention in the experimental group A has better antibacterial ability because the samples in the experimental group A have less bacterial growth under the same conditions.
Analysis of chemical composition
Two high-silicon porcelain are selected as materials, and one high-silicon porcelain prepared by adopting the material is used as an experimental group A; another high silicon ceramic prepared from traditional materials was used as experimental group B.

Comparison analysis: the chemical composition data of experimental group a and experimental group B were compared, with particular attention paid to the difference in silicon content, and statistical analysis was performed to understand the possible effect of different chemical compositions on porcelain performance, as shown in table 7.
TABLE 7 element content data sheet
| Sample type | SiO 2 Content (%) | Al 2 O 3 Content (%) | Fe 2 O 3 Content (%) | Other element content (%) |
| Experimental group A | 70 | 15 | 2 | 13 |
| Experiment group B | 65 | 20 | 3 | 12 |
As shown in Table 7, it is possible to obtain the Silicon (SiO) of experiment group A (high silicon porcelain prepared by using the material of the present invention) 2 ) The content was 70%, whereas the silicon content of experimental group B (high silicon porcelain prepared from conventional materials) was 65%. Indicating a relatively higher silicon content in the porcelain of experimental group a. The porcelain samples of the experimental group a and the experimental group B contained alumina (Al 2 O 3 ) Iron oxide (Fe) 2 O 3 ) As well as other elements. Of these elements, the contents of experimental group a were 15%, 2% and 13%, respectively, while the contents of experimental group B were 20%, 3% and 12%, respectively. Since silicon is one of the main components in porcelain, the difference in its content may have an influence on the performance of porcelain. Higher silicon content results in porcelain having higher compressive strength, wear resistance and chemical resistance.
