Learning objectives
The goal of this course is to investigate technical properties of stone materials and analogue ceramic materials, including cement/concrete systems, by means of methodologies adopted by petrology.
Expected learning outcomes
The student will practice and acquire the methods required to manage datasets of technical properties for stone and ceramic materials, and will be able to design and engineer innovative applications for natural and synthetic materials.
Course syllabus and organization

Single session

Responsible
Lesson period
First semester
Should the health emergency persist in the second semester, the lessons will be held on the Microsoft Teams platform and can be followed both in synchrony on the basis of the first quarter schedule and asynchronously because they will be recorded and left available to students on the same platform. .

Program and reference material
The program and reference material will not be affected.

Methods for verifying learning and evaluation criteria
The exam will take place orally using the Microsoft Teams platform or, where the regulations allow, in person, in writing.
Course syllabus
APPLIED PETROLOGY
Physical and technical properties of stones and ceramic materials. Certificates and international standards.
Transforming natural raw materials and the production cycle for ceramics. Processes and tools for producing powders, shaping and forming green composites.
Designing a ceramic material: phase diagrams, volatility diagrams. Binary and ternary diagrams with phases of fixed composition. Equilibrium and fractional processes. Principles of ternary phase diagrams with solid solutions. Methods for the construction of phase diagrams using experimental data and thermodynamic computation. Interpretation and use of databases. Phase relationships and natural vs. synthetic materials in the diagram Al2O3-SiO2 (use and properties of pyrophyllite, andalusite, kaolin, mullite, corundum, etc.); Phase relationships in the system MgO-Al2O3-SiO2 (steatite, cordierite, forsterite, spinels). Phase relationships and natural vs. synthetic materials in the diagram CaO-Al2O3-SiO2: the usage of carbonatic rocks in cements, in metallurgy, and in ceramic applications. Concretes. Non-oxides: examples in the system Si-N-C-O.
Producing ceramics: Process variables: temperature, pressure, partial pressure of gaseous species, time. Kilns and furnaces. Synthesis and sintering at environmental and high pressure. Liquid phase sintering.
Quantitative textural analysis of rocks and ceramic materials and relations with physical properties. Principles governing textures. (nucleation, growth, diffusion, etc.). Transformation-Time-Temperature diagrams. Creep in natural and synthetic materials. Creep textures. Fracturing and toughening. Quantitative morphological analysis
The stone market: dimension stones, marbles, granites, stones - commercial definitions. Commercial varieties. Mining technologies and production cycle. Transformation of stones, from blocks to polished slabs and special treatments. Applications.
Practicing in laboratory, in the field and in the industry is programmed.
Prerequisites for admission
The program requires good knowledge of petrography. It is also advisable to bear the contents of the teaching of petrology
Teaching methods
Type of exam: Written;
Frequency: Strongly recommended;
Delivery method: Traditional.
Activities are planned in the field and in the laboratory, in industries of the stone and ceramics sector
Teaching Resources
During the course both the powerpoint presentations discussed in class and the literature concerning the illustrated cases will be provided. The material is available on the Ariel website:
