Abstract
The present invention discloses a homogeneous microstructured ceramic material that allows replicating the microstructure of the skeleton of a stony coral, as well as its physical, chemical, and biological behavior, useful for promoting the growth of biological material and obtaining a scalable structure for the standardized measurement of seafloor parameters. Furthermore, it discloses a method that allows obtaining the material with the desired properties and a device to be placed in the oceans and wetlands, which comprises said microstructured ceramic material.
Claims22

- 76%-79% fine powder limestone (110);
- 21%-24% binder (120);
- wherein said ceramic material has a compressive strength between 7 and 10 MPa, a dry bulk density between 1.3 and 1.5 g/cm3, a connected porosity between 43% and 51%, and an average pore diameter between 500 and 900 μm,
A method (200) of obtaining a microstructured ceramic material (100), said method comprising:
- a. Preparation of raw material (210), with the following steps:
- a. Activating and compacting a binder (211);
- b. Fragmenting and pulverizing a limestone (212) to a final diameter between 4 and 15 μm in more than 60% of the sample and an average diameter between 10 μm and 13 μm;
- and
- c. Fracturing a binder;
- Wherein said raw material comprises between 74% and 76% limestone, between 21.1% and 22.2% binder, and between 3.7% and 3.8% porosity generator.
- b. Homogenization (220), wherein a ceramic material matrix is obtained;
- and
- c. Obtaining (230) of the material, with the following steps:
- a. Curing the matrix (232);
- and
- b. Synthesizing the matrix (233), wherein the matrix is sintered for 2 h to 6 h using the temperature curve:
- i. Increasing the temperature from 118 to 148° C. with a slope of 0.5° C. min−1, up to a temperature between 400° C. and 900° C.;
- ii. Maintaining the temperature reached in i. stable for 3 h;
- and
- iii. Cooling the resulting material in a controlled manner to room temperature to obtain the material (100).
