The powders produced are spherical; between 100 and 300 m is size, with good packing and flow characteristics, making the powder ideal for high quality, near net shapes produced by HIP, such as aviation parts and porous coatings on hip prostheses.

Maurice Edmond Müller (March 28, 1918 - May 10, 2009) was a Swiss orthopedic surgeon who was instrumental in the development of internal fixation techniques to treat bone fractures and who also significantly advanced the development of the hip prostheses.
