Description
Es sind Trockengleichrichter bekannt, bei welchen zwischen Elektroden, die insbesondere plattenförmig ausgebildet sind, eine feste Ventilschicht angeordnet ist. Als Material dieser Schicht dient z. B. Kupfersulfid, Kupferoxydul, Selen, Tellur usw.There are dry rectifiers known in which between electrodes, in particular are plate-shaped, a solid valve layer is arranged. As a material of this Layer serves z. B. copper sulfide, copper oxide, selenium, tellurium, etc.
Es hat sich gezeigt, daß es von großem Vorteil ist, dem Material der Ventilschicht Alkalimetalle in geringer Menge zuzusetzen.It has been shown that it is of great advantage to add alkali metals to the material of the valve layer to be added in a small amount.
Für Detektoren, die zur Gleichrichtung elektrischer Wellen in der drahtlosen Telegraphie und Telephonie, also hochfrequenter Wechselströme verhältnismäßig kleiner Leistungen, dienen und bei denen der wirksamen Substanz eine feine Spitze als Gegenelektrode gegenübersteht, sind solche Alkalimetallzusätze bereits bekannt. Neu ist dagegen diese Beimengung zur Ventilschicht von Trockengleichrichtern, die zur Umwandlung von niederfrequenten Wechselströmen größerer Leistung in Gleichstrom dienen.For detectors used to rectify electrical waves in wireless telegraphy and telephony, that is, high-frequency alternating currents of relatively low power and where the active substance is faced with a fine tip as a counter electrode, such alkali metal additives are already known. What is new, however, is this admixture to the valve layer of dry rectifiers, which are used to convert low-frequency Alternating currents of greater power are used in direct current.
Als besonders wirksam erwies sich der Zusatz von Alkalimetallen zu solchen Ventilschichten, die aus metallischem Selen oder aus Tellur bestehen. The addition of alkali metals to such valve layers proved to be particularly effective, which consist of metallic selenium or tellurium.
Es ist für den Erfindungsgegenstand ohne Bedeutung, ob die Alkalimetalle in Form von Legierungen oder Mischungen oder in Form von chemischen Verbindungen wirksam sind.It is irrelevant for the subject matter of the invention whether the alkali metals are in the form of Alloys or mixtures or in the form of chemical compounds are effective.
Gleichzuachten mit der Zusetzung von Alkalimetallen ist die Auswahl von solchem Material zur Ventilschicht, welches schon als Rohmaterial oder infolge eines entsprechend gearteten Herstellungsverfahrens die erforderliche Menge Alkalimetall enthält.Equal to the addition of alkali metals is the selection of such material to the valve layer, which is already used as a raw material or as a result of a corresponding type Manufacturing process contains the required amount of alkali metal.
Von den Alkalimetallen haben sich Natrium und Lithium als hervorragend geeignet erwiesen. Of the alkali metals, sodium and lithium have proven to be extremely suitable.
Die Menge der Alkalimetalle, die zuzusetzen ist, richtet sich sowohl nach der Art der Ventilschicht als auch nach der Art des zu wählenden Alkalimetalls. Es hat sich herausgestellt, daß die günstigste Wirkung bei 5 % un(i darunter eintritt.The amount of alkali metals to be added depends both on the type of valve layer and on the type of alkali metal to be selected. It has been found that the most favorable effect occurs at 5% un ( i below.
Der Alkalimetallzusatz kann selbstverständ-Hch auch mehrere Alkalimetalle zugleich enthalten. The alkali metal additive can of course also contain several alkali metals at the same time.
Bei Anwendung einer Gleichrichterschicht, die aus einer Vereinigung von Selen oder Tellur mit Alkalimetall besteht, ergibt sich der Wert der vorliegenden Erfindung besonders deutlich. Es beträgt nämlich das Verhältnis der Widerstände der beiden Stromrichtungen des Ventils 1000 : ι oder darüber, während man normalerweise im Betriebe nur etwa 300 : 1 erreicht.When using a rectifier layer made from a combination of selenium or tellurium with alkali metal, the value of the present invention is particularly evident. This is because it is the ratio of the resistances of the two directions of flow of the valve 1000: ι or above, while normally only reached about 300: 1 in operation.
