CoorsTek, Inc. is a privately owned manufacturer of technical ceramics for aerospace, automotive, chemical, electronics, medical, metallurgical, oil and gas, semiconductor and many other industries.

[9] After World War I, Coors Porcelain made tableware and cookware bearing the trademarks Rosebud, Glencoe Thermo-Porcelain, Coorado, Mello-Tone and others.

The 440,000 sq ft (41,000 m2) Ninth St. plant consists of several adjoining buildings that occupy four square blocks, and was CoorsTek's largest manufacturing site until it closed in 2021.

Herman's older brother, Grover Cleveland Coors (1888–1954), began the fledgling company's foray into ceramic technology by inventing a tool for forming spark plug insulation in 1919.

Herman Coors offered to buy Porcelain in the early 1920s after frequent management disagreements with his father and older brother, but was refused.

[15] In the 1950s, Coors Porcelain's parent company investigated the possibility of replacing steel beverage cans with aluminum ones, as part of a closed-loop recycling system.

A Porcelain warehouse at the corner of Ninth St. and Washington Ave. in Golden was selected to house the pilot plant for the aluminum can line.

Coors success with the aluminum industry was a critical breakthrough in the development of America's recycling market and collection infrastructure.

[18] Coors Brewing Company reorganized its 340-employee can, end and tab operations into a joint venture with the Ball Corporation in 2002, known as Rocky Mountain Metal Container LLC.

[24] Lawrence Radiation Laboratory awarded Coors a 2-year contract in 1963 to produce enriched urania-beryllia fuel elements for Project Pluto's Tory II-C nuclear ramjet engine, which increased employment by 230 to a then-record 1100 total.

[58] In 1993, Coors sold circuit board manufacturer Microlithics Corp. to VisiCom Laboratories, and its ceramic subsidiaries in Ocean Springs, Mississippi and Rio Claro, São Paulo, to undisclosed buyers.

[60] In 2000, ACX was dissolved and Coors Ceramics became an independent, publicly traded company under the name CoorsTek, Inc.[61], [62] Annual revenue was $334M and an operating loss of $32M was reported for 1999.

[68] John Coors had been the president of Golden Genesis Corp. (GGC), a manufacturer of photovoltaic devices for solar power collection in Scottsdale, Arizona.

ACX owned 55% of GGC stock (Nasdaq: GGGO), which it sold to Kyocera Solar Inc. in 1999 for $30 miilion[69] CoorsTek signed an agreement in June 2010 to buy certain assets of the Advanced Ceramics division of the French conglomerate Saint-Gobain.

The transaction was completed in January 2011, with CoorsTek assuming ownership of six plants in Europe; four in the USA; one each in Canada, Mexico and Brazil; and sales offices in Japan, China, Taiwan and Singapore.

Johnson had been a ceramic engineer and project director at the Alumina Research Division of Reynolds Metals Co. in nearby Bauxite, Arkansas.

[124] Ceramatec was founded in Salt Lake City in 1976 by University of Utah Professors Ronald S. Gordon, Al Sossin and Anil V. Virkar, to develop liquid-core, sodium-sulfur batteries for automotive applications.

The battery uses a beta-alumina solid electrolyte (BASE) ceramic membrane to separate the sulfur anode and sodium cathode.

[126] David W. Richerson, author of Modern Ceramic Engineering (2nd Ed., Marcel Dekker Inc., 1992), was hired in 1985 and became the VP for applied technology until he left in 1992.

[129] Ashok V. Joshi, an expert in solid oxide fuel cells (SOFC) and the VP, bought the company from Elkem in 1999 and became president in 2000.

[130] A new subsidiary, CoorsTek Membrane Sciences AS, was launched in Oslo, Norway, in 2015 to commercialize BASE, SOFC and other ion-separating technologies developed by Ceramatec, under the direction of Per Christian Vestre.

[134] The product, sold under the name Cerestore, raised some concerns among dentists for its wear on opposing teeth and its accuracy of fit.

In 2017, the 70-employee operation, managed by Mark Cameron, signed a contract to manufacture ceramic components for Teledyne e2v's radiotherapy machines.

"Woodie" Howe (1942–2006) managing both operations and reporting to John Jenkins, VP and GM of Coors Ceramics Structural Division.

The Tennessee location was chosen to take advantage of the technology transfer programs at Oak Ridge National Laboratory's High Temperature Materials Lab.

[86] Howe, a Coors employee from 1962 to 1999, was promoted to VP of the Structural Products Group in 1996, which included CTCC operations in Tennessee, Oklahoma, California and Texas, and ACI in Arkansas.

[150], [151] In 1966, Maginnis developed a way of making alumina pump plungers for the oil and gas industries, replacing steel and other metals that corroded too easily.

[152] The 1996 acquisition of HB Company's newer operation in Oklahoma City led to closure of the plant in Norman and its relocation to the state capital.

The components included suction box covers, foil sections, Versafoil forming tables and cleaning cones.

Bill Wilbanks, a ceramic engineer at Tektronix in Portland[153] before he started his namesake firm, managed the 170-employee Coban plant in Brazil in the mid-1980s until his retirement from Coors.
