Title: Jitka Kirchnerova: Innovator in Ceramic and Sensor Technologies
Introduction
Jitka Kirchnerova is a prominent inventor based in Montreal, Canada. She has made significant contributions to the fields of ceramic materials and electrochemical sensors. With a total of 4 patents, her work showcases innovative processes and technologies that have practical applications in various industries.
Latest Patents
One of her latest patents is a process for making fine ceramic powders from aqueous suspensions. This innovative preparation process utilizes lanthanum oxide as a precursor, which is mixed with water to create a liquid slurry. The slurry undergoes a transformation into hydroxide through a reaction with water. The resulting hydroxide slurry can be milled to reduce particle size and enhance reaction speed. This slurry is then combined with metal nitrate precursors, such as strontium and cobalt nitrates, to produce a colored slurry of metal hydroxides. The perovskite precursor slurry can be processed through spray-freezing and freeze-drying or spray-drying, followed by controlled calcination to yield nearly phase-pure perovskite with a specific surface area exceeding 10 m²/g.
Another notable patent is a solid-state arsenic probe designed for use in pyrometallurgical processes. This potentiometric electrochemical sensor detects gaseous concentrations of arsenic oxides at elevated temperatures. The sensor comprises an ionically conducting solid-state membrane, a reference electrode, and a working electrode. It is responsive to arsine concentrations ranging from 5-1000 ppm in oxidizing gases at temperatures between 600°C and 900°C. The compound silver zirconium arsenate, used in the sensor, is also a novel contribution to the field.
