Ph.D. Dissertation in Applied Sciences Explores the Synthesis and Physicochemical Properties of Heat-Resistant and Radiation-Protective Glass Ceramics
A Ph.D. dissertation by student Fatima Hussein Farhan was discussed in the Department of Medical and Industrial Materials at the College of Applied Sciences, University of Technology. The dissertation is titled:
“SYNTHESIS AND PHYSICOCHEMICAL PROPERTIES OF HEAT-RESISTANT GLASS CERAMICS AND RADIATION-PROTECTIVE GLASSES AND THEIR PROSPECTS WHEN USING SAND FROM IRAQI DEPOSITS“
The defense took place in the late Prof. Dr. Abdul-Muttalib Ibrahim Al-Sheikh Hall within the college.
The research focused on the development and characterization of glass ceramics resistant to thermal shock and glasses capable of shielding radiation. It involved an in-depth study of lithium-aluminosilicate glass ceramics, known for their distinctive properties that particularly their ultra-low thermal expansion coefficients, approaching zero.
The dissertation also explored advanced manufacturing methods, including reducing melting times, optimizing heat treatment processes, and developing a new system to achieve near-zero thermal expansion. The study led to the production of novel glass formulations and introduced an innovative method for enriching Iraqi sand to extract high-purity crystalline nano-silicon oxide. This material was then successfully utilized in the production and enhancement of thermal shock-resistant glasses.
