Porous mullite ceramics with an open/closed pore structure were prepared by protein foaming method combined with fly ash hollow spheres. Both the open porosity and total porosity of samples were enhanced by increasing the hollow sphere content. Mullite whiskers with a diameter of 0.2–4 μm were grown in-situ in the porous mullite ceramics with an AlF3 catalyst, conforming to a vapor-solid growth mechanism. The pore structure of the porous mullite ceramics was significantly affected by the mullite whiskers which increased the open porosity and total porosity. Moreover, the median pore size was reduced from 65.05 μm to 36.92 μm after the introduction of mullite whiskers. The flexural strength and the thermal conductivity of the samples decreased with increasing total porosity. The porosity dependence of the thermal conductivity was well described by the universal model, providing a reference for the prediction of thermal conductivity of porous ceramics with open/closed pores.

The effect of phosphorus on the formation of mullite whiskers from citric acid activated kaolin

Mullite whiskers are potential candidates for improving the mechanical and thermal properties of ceramic, glass, and composite material. In this work, well-developed whisker-shaped mullite has been produced by adding tribasic calcium phosphate (Ca3(PO4)2) into kaolin before calcining in air. In the raw kaolin, rod-like mullite crystal of ~0.5-1.0 μm length and ~0.05-0.2 μm diameter formed at 1350°C, and mullite whiskers were not be observed; however, by doping 6 wt% Ca3(PO4)2 into kaolin, mullite whiskers of ~5.5 μm length and ~0.05-0.10 μm diameter grew at 1250°C. The formation of high aspect ratio of mullite whiskers can probably be explained by the synergistic effect of P2O5 and CaO, resulting in the formation of liquid phase with a relatively higher content of Si and a lower viscosity at low temperature of 1250°C, which facilitates the growth of mullite displaying acicular morphology. The results are of interest in producing high aspect ratio of mullite whiskers from kaolin at reduced calcination temperatures.

Preparation of mullite whiskers from kaolin via the addition of tribasic calcium phosphate

The invention belongs to the technical field of coatings, and discloses bright-yellow high-near infrared reflection ferric-doped bismuth molybdate pigment and preparation and application thereof. Thebright-yellow high-near infrared reflection ferric-doped bismuth molybdate pigment has a chemical composition of Bi(2-x)FexMo3O12, wherein x = 0.01-0.4. The preparation method comprises the followingsteps: (1) preparing ammonium molybdate, a bismuth salt and an iron salt into solutions separately so as to obtain an ammonium molybdate solution, a bismuth salt solution and an iron salt solution; (2) mixing the bismuth salt solution with the iron salt solution so as to obtain a mixed solution, adding the mixed solution to the ammonium molybdate solution, adjusting the pH value of the system to 7-9, and continuing to heat for a reaction so as to obtain a precipitate; and (3) drying the precipitate, performing heat treatment and ball milling so as to obtain the ferric-doped bismuth molybdate pigment. The method is simple, the obtained pigment has vivid bright-yellow color and a property of extremely high reflection of near-infrared band light, and the total reflectance is more than 95%; and the pigment can be applied to preparation of high-near infrared reflection coatings.
