A system and associated method constructs a building material from lunar soil. A magnetic sorter magnetically sorts the lunar soil and the system creates a layered surface comprising a microwave susceptible, thermal conductive top layer of lunar soil and a poorly microwave-susceptible and poorly thermally conductive sublayer of lunar soil. A microwave generator generates microwave energy into an antenna and directs the microwave energy onto the top layer of lunar soil to sinter the microwave susceptible, thermal conductive top layer of lunar soil.

A multicolor light-storing ceramic for fire-protection indication and a preparation method thereof are provided. The preparation method includes: adding a glass based raw material, a light-storing powder, a dispersant and an alumina powder into a granulator, adding water mixed with a pore-forming agent and then mechanically stirring for granulation; adding a plasticizer after the stirring of 4˜8 h, and continuing the stirring for 1˜3 h to thereby obtain a mixture; packing the mixture into a mold and performing tableting; demolding and obtaining a light-storing self-luminous quartz ceramic by drying and firing using a kiln; printing a pattern onto a surface of the ceramic and then curing to obtain a light-storing ceramic for indication sign. Using an industrial waste glass has advantages of low sintering temperature and green environmental protection; dispersed pores and alumina introduced as scattering sources improves light absorption efficiency, fluorescence output phase ratio and light transmission of the ceramic.

A non-spray-drying, dry-granulation process for making a ceramic particulate mixture including from 4 wt % to 9 wt % water. At least 90 wt % of the particles have a particle size of from 80 μm to 600 μm. The process includes the steps of: (a) forming a precursor material; (b) subjecting the precursor material to a compaction step to form a compacted precursor material; (c) subjecting the compacted precursor material to a crushing step to form a crushed precursor material; and (d) subjecting the crushed precursor material to at least two air classification steps. One air classification step removes at least a portion of the particles having a particle size of greater than 600 μm from the crushed precursor material, and the other air classification step removes at least a portion of the particles having a particle size of less than 80 μm from the crushed precursor material.
