Quartz glass has a range of excellent physical and chemical properties, including good mechanical properties, due to its special structure and composition (usually high purity silicon dioxide SiO₂). The following are some of the mechanical property characteristics of quartz glass:
- Theoretical Strength: The theoretical calculated strength of quartz glass is very high, about 24 x 10⊃3; MPa, but in practice, due to defects inside and on the surface of the material, its actual strength is much lower than this theoretical value.
- Brittleness: Although quartz glass has high mechanical strength, it is also notable for its brittleness, which means that it tends to break rather than deform plastically.
- Modulus of elasticity: Quartz glass has a modulus of elasticity of approximately 700 x 10⊃3; kg/cm² (equivalent to approximately 70 GPa), which means that it resists deformation when subjected to force.
- Tensile strength: Quartz glass has a tensile strength of approximately -500 kg/cm² (equal to approximately 50 MPa), which means it can withstand a certain amount of tensile stress without breaking.
- Compressive Strength: Quartz glass has a high compressive strength, with a recommended design compressive strength of 1.1 x 10⁹ Pa (equal to approximately 1100 MPa).
- Hardness: Quartz glass has a Mohs hardness of about 7, which means it can resist some degree of scratching and abrasion.
- Temperature effects: Certain mechanical properties of quartz glass, such as modulus of elasticity, tensile strength and flexural strength, increase with temperature, peaking at specific temperature ranges.
In summary, quartz glass has excellent mechanical properties, but due to its brittleness and the presence of surface defects, care needs to be taken in practical applications to avoid impacts and to avoid the creation of new surface cracks.
