| Tensile strength | 4.7 x 107Pa(n/m2) |
| Compressive strength | >1.1 x 109Pa |
| Coefficient of thermal expansion (20 oC -300 oC) | 5.5 x 10-7 cm/cm oC |
| Thermal conductivity (20 oC) | 1.4w/m oC |
| Specific heat (20 oC) | 660J/kg oC |

Remark：
Thermal stability- The transparent quartz tube was heated to about 1100 oC for 15 minutes. And then immediately quenched into water(about 20 oC). Repeated three times tests will not have cracks, gaps and more than 3mm avalanche.
