Abstract

A novel freezing unit was developed for use in ceramic processing by the freeze casting technique. This step is crucial, since the macrostructure promoted by this technique is formed during freezing. Several authors present basic information about the apparatus used in the freezing step, but there are no studies that describe a complete unit as we do in this work and there is no commercial equipment for this purpose. The components of the freezing unit were selected according to function, suitability to project, cost and market availability. Advanced ceramic samples of ZnFe2O4, MnFe2O4, CoFe2O4, NiFe2O4, SiO2, Al2O3 and metallic Cu were produced using the freezing unit and the results of typical macrostructure and porosity analysis validated the chosen setup.

自制的冰模板冷冻装置

采用冷冻铸造技术，研制了一种用于陶瓷加工的新型冷冻装置。这一步骤至关重要，因为该技术促进的宏观结构是在冷冻过程中形成的。几位作者介绍了冷冻步骤中使用的设备的基本信息，但没有像我们在这项工作中所做的那样描述完整单元的研究，也没有用于此目的的商业设备。冷冻装置的部件是根据功能、项目适用性、成本和市场可用性进行选择的。使用冷冻装置制备了ZnFe2O4、MnFe2O4和CoFe2O4的高级陶瓷样品，NiFe2O4，SiO2，Al2O3和金属Cu，典型的宏观结构和孔隙率分析结果验证了所选择的装置。

期刊介绍： The Journal of Applied Research and Technology (JART) is a bimonthly open access journal that publishes papers on innovative applications, development of new technologies and efficient solutions in engineering, computing and scientific research. JART publishes manuscripts describing original research, with significant results based on experimental, theoretical and numerical work. The journal does not charge for submission, processing, publication of manuscripts or for color reproduction of photographs. JART classifies research into the following main fields: -Material Science: Biomaterials, carbon, ceramics, composite, metals, polymers, thin films, functional materials and semiconductors. -Computer Science: Computer graphics and visualization, programming, human-computer interaction, neural networks, image processing and software engineering. -Industrial Engineering: Operations research, systems engineering, management science, complex systems and cybernetics applications and information technologies -Electronic Engineering: Solid-state physics, radio engineering, telecommunications, control systems, signal processing, power electronics, electronic devices and circuits and automation. -Instrumentation engineering and science: Measurement devices (pressure, temperature, flow, voltage, frequency etc.), precision engineering, medical devices, instrumentation for education (devices and software), sensor technology, mechatronics and robotics.
